RoboSavvy Humanoid Design Challenge

Medium

Robosavvy is looking for your help in gathering fresh ideas for the design of a new humanoid robot designated for entertainment and education. Our objective is to launch a new open-source humanoid robot that will look great and will be agile and smart at a reasonable cost.

Comparable education and research humanoid robots cost over $10,000 due to their plastic molded shell parts, expensive actuators and closed-source business approach. We want this to be an open-source robot that will outperform its rival platforms while keeping the cost of materials to about $1,000. We will achieve this by utilizing materials and fabrication methods available to anyone. Materials include aluminum sheet and 3D printed parts for structure, vacuum formed polycarb exterior shell, servos for actuation and low cost electronics including Raspberry Pi for brains.

THE SELECTION OF THE BEST ROBOT DESIGN WILL BE BASED ON THE FOLLOWING FEATURES

⇒ The exterior of the robot needs to hide the metal frames and servo boxes as much as possible, exposing a streamlined exterior with a distinct look and features
⇒ The robot’s range of movements with its shell should allow it to walk, crawl and get up from laying on front and back. The acting servos should have enough torque to be able to work against gravity in each of these motions
⇒ The design should incorporate additional range of motions including torso rotation to allow crawling, hands with grasping capabilities and pan/tilt motion of the head

We expect to have to do some modifications to the chosen design to make the robot perform the featured range of motions because we realize the designer may not have all the practical experience designing humanoid robots. We will adapt the shell if needed for polycarb vacuum forming. We will also handle the electronics involved in power management and servo control, in addition to developing the core open-source software to make the robot move, including ROS support, simple python scripts and physics simulation.

DESIGN GUIDELINES

⇒ Actuation should be based on Robotis AX12 and AX18 servos. Smaller servos can be used in order to actuate body parts that have little weight and don’t need the high torque servo. For example pan/tilt on the head and grasping action in the hands. These servos can be chosen from the Hobbyking catalogue (ex1, ex2). The Robotis servos are designed for robotics, have great price/size/performance and they can be daisy-chained and controlled with a tiny USB board. However, they may be too bulky for the pan/tilt motion of the robot’s head or the hand with grasping action, hence the small PWM RC servos can be used and we will add a designated USB interface board to control them from the embedded Linux.
⇒ The structure of the robot’s skeleton should be made with aluminum sheet of 1.5mm thickness. See the Bioloid GP and Darwin-OP or any Robo-One robots for examples of how to use aluminum sheet as structure for humanoid robots. Aluminum folded brackets models should easily convert or be made available as flattened pieces to allow precise cutting and bending.
⇒ Some structural parts can also be designed for fabrication using desktop 3D printing or CNC where aluminum sheet pieces don’t easily address a structural challenge.
⇒ The number of servos and the aluminum structure will determine the size, degrees of freedom and agility of the robot. The design should consider the torque limitations of the servos. For example, the knee servos should be able to lift the upper body of the robot and the feet should be able to tilt the robot during a walking gait. More servos, more weight and more height will limit the ability of the lower body joints to handle the weight and momentum.
⇒ The height of the Darwin-OP with its more powerful servos is 45cm (3kg), the Bioloid with its plastic brackets is 40cm (1.7kg) and the GP with its metal brackets is 35cm (1.6kg). The design may incorporate double knee joint to assist in giving more lifting power to the upper body.
⇒ The servos may directly actuate a joint using a metal bracket, or indirectly through other types of linkages or other transmission of actuator effect such as pulleys and Kevlar/braided fishing wires (ex) to allow better mobility, stability, or streamlining the joints to create a more biologically inspired look.
⇒ To allow the robot to grasp, one or more small servos as described before, can be used to actuate two or more fingers. (ex1, ex2) Grasping can be achieved with a single servo and two or more spring-loaded fingers. It can use more servos to achieve more mobility at the cost of weight. Wrist and arm rotation should also be considered to allow the robot mobility to write with a pen.
It is not necessary to place every screw and bolt in the model where their place is obvious such as holding the servo horn to the metal bracket.
⇒ The design can incorporate additional inexpensive and easily sourced off-the-shelf elements such as springs, wires, machine screws/nuts/spacers, magnets, bearings or RC suspension spring-damper and push-rods. The design can incorporate custom 3D printed parts and also machined parts if necessary.
⇒ Ensure that the robot parts can actually be assembled and that there are no parts or screws that are occluded in a way that will prevent them from quick assembly.
⇒ The robot needs to have an accessible area designated for electronics including Raspberry-Pi or Beaglebone Black and some extra padding space around for wires and additional electronics such as an IMU, voltage regulator, USB connectors and speakers.
⇒ The robot needs to host a 3-cell Lipo battery that can be easily replaced. Any size and shape battery found here can be used weighing up to 150g and having at least 1200mah capacity 15C or higher.
⇒ A miniature web camera should be present on the robot's head or chest. It can be any miniature webcam that's easily purchased on amazon or ebay, preferably with hardware JPEG encoding. The webcam will typically be stripped off its plastic shell to save space.
⇒ The look of the robot is primarily defined by the exterior shell. The robot's body should be covered by a thin vacuum formed colored polycarbonate sheet shell to hide the metal framed body and servo boxes and give the robot a more streamlined look such as that of Asimo, QRIO, NAO, Manoi, Kirobo or Darwin-OP. The thickness of the Polycarb in the design should be 0.5mm. We will try to make the shell work with as thin a sheet as possible (to make it lighter) while ensuring it is not too weak at the contact points with the metal structure and able to handle any stress caused by falling. RoboSavvy may need to adjust the shell to make it vacuum formable. For example, it may need to be split into two halves and adjusted to create nice seams due to the split.
⇒ The shell design should not obstruct the motion range of the robot's joints.
⇒ The robot may incorporate LEDs anywhere on the body. The shell may also include light masking areas or areas that diffuse LED light underneath to give the shell lighting effects such as in Tron and Iron Man.
⇒ Anyone with access to a hackerspace workshop with the following hobby tools should be able to fabricate the open-source humanoid robot:
- desktop 3D printer for printing parts in PLA and ABS
- CNC to cut out aluminum sheet and MDF to cut out a - mold for vacuum forming
- pan/break machine to bend the aluminum sheet
- vacuum forming setup to clamp, heat and vacuum polycarb sheet on top of the mold

Was wondering how to improve an already super cool robot over dinner just now...LOL I think RoboSavvy is looking at cost down...LOL Read last few words from first paragraph "Our objective is to launch a new humanoid robot that will look great and will be agile and smart at a reasonable cost." I see reasonable and reachable cost are what lacking in Bioloid GP now :p

    @adrien i admit to what you say, the current bioloid gp looks super cool, and adding more design to its aluminium body can increase the price on the current model, one can cover up the body and stuff led's to give it a tron or the iron man look..one has to change or cut down the metal to meet their requirement for a reasonable price

    I am just wondering about the 1st prize, What would you possibly do with a robot?
    if the cost of this robot is 4000$ couldn't you just give the money prizes?
    And also reward the second and third place because I think that there will be many cool entries here and it would be a shame not to reward great designs as well.
    Just an idea ;)

    Since the chassis has to be made from folded Aluminium, do you want the full sheet metal development of the parts (easy in Solidworks) or just 3D 'shells' and you will figure out how to fold it from sheet?
    You have specified the Servos - to avoid any confusion, could you list the specifications of those servos you work to - as real world is usually different to the manufacturers spec. Mainly max speed, acceleration, resolution & holding torque.

    Likewise, it would be helpful if RoboSavy could link to the models THEY use for servos etc. I've found a couple of RPi models which are different, and neither matches my RaspberryPi exactly!

    Also, you have specified "will look great and will be agile and smart at a reasonable cost" as the judging criteria.
    Can you give us the balance between these you are going to use to score entries.

    For example, will an ugly, agile, cheap robot win over a good looking, clumsy, cheap robot?

    Sorry for a third question.
    In the last part of the description it says "RoboSavvy is creating the most advanced 1m tall research humanoid robot in the world, a 3D printable low cost humanoid robot that looks like Honda Asimo"
    Is that what this challenge is to design? Or something along those lines - i.e. a 1m tall relation of Asimo?

    @Sara Please ask RoboSavvy to increase the number of types of servo (included dimensions & performance chart), including those they didn't carry. That will increase the variants. Restrict the overall size too. State clearly how many axis (degree of movement) and where they want them. Else we will see designs get disqualify because of some hidden requirements or last minute changes. Thanks =)

    I'm from RoboSavvy and I'll try to answer your questions.

    GP model: First of all, we have put together a CAD model of the GP which we have passed onto Grabcad. A link should show up on this page any time now.

    servo model: You can find a detailed model of the AX12 / AX18 servo here: http://humanoids.dem.ist.utl.pt/Iden_external/overview.html

    battery model: you can use any size and shape found on hobbyking weighing up to 150g and of at least 1200mah ( http://goo.gl/WP98nm )

    camera: we will post the model or dimensions of a tiny usb camera found on ebay and stripped off its plastic shell.

    CPU board: Rpi and BeagleBone black models can be found using google. the space should have clearance either of the two.

    Tan & vineetv: couple of points regarding your previous comments about cost, adding aluminum and shell etc.
    We would like to see a nice looking humanoid robot shell, exposing as little as possible the motors and brackets. If you look at pictures of Asimo you will notice that there are no "technical" detail exposed anywhere on its body.
    The cost of the robot has a lot to do with the servos and the manufacturing process of everything else. We are looking for a cool look and we may modify the design and structure slightly to reduce the cost of manufacturing.

    @Limor - so you are looking for something based on your existing GP robot, with changes to the aluminium components where necessary to attach the shell. The challenge thus is to design a cool looking shell rather than to re-invent the robot itselfv

    Simonv:
    "do you want the full sheet metal development of the parts (easy in Solidworks) or just 3D 'shells' and you will figure out how to fold it from sheet" - it will be nice if you can also provide the flattened version.

    "...servo specification..." : the Robotis servos are not like any RC servos, they are designed for robotic applications and the specifications are pretty close to reality

    "...servo models..." : i've posted a link (..ist.utl.pt) to a servo model that was precisely measured from a real AX12 servo

    "...Rpi model.." : just make sure there's enough clearance somewhere for an RPi and beagle bone (either one should fit in). We can later adjust the model to ensure there are screw holes in the aluminum and/or some 3d printed base

    "...1m tall robot..." : we are building a 1m tall humanoid with a nice shell design. http://goo.gl/pkbsYv . This robot design challenge is about a robot that is 40-50cm. ( fyi: To make a 1m tall robot walk you need to use servos that are 10 times more powerful and 30 times more expensive. c

    Gochat: "what options are sheet metal thickness selection and what is the maximum size of the robot?" -- The aluminum can be 1.5mm-2mm. We will have to see the final design and maybe tweak to ensure it wont bend or tear, while trying to minimize weight.

    Robot Height: at least 35cm and probably no more than 50cm. Depending on weight distribution he may not be able to walk if the knee/foot/hip servos need to swing too much mass X distance.

    Frederiv : the thickness of the polycarb shell can be 0.5mm. The important thing is the look of the robot. We will try to make the shell work with as thin a sheet as possible (to make it lighter) while ensuring it is not too weak at the contact points with the metal structure, to handle any stress caused by falling. The shell may need to be adjusted later to make it vacuum formable. (for example, it may need splitting into two halfs and adjusted to create nice seams due to the split..)

    Tan: "Please ask RoboSavvy to increase the number of types of servo (included dimensions & performance chart.." -- that's an interesting one. If you want to use an alternative servo to the AX12/AX18 please suggest some ideas. Please refer to hobbyking servos.
    The choice of Robotis servos is because we know everything there is to know about them and they are great for robotic applications and few servos match their price/size/performance. We also know how to control them directly from Rpi/Beagle with only a small USB interface board. However, the AX12 is bulky and if you want to add a pan/tilt head to the robot, or a hand with fingers, you would have a hard time doing it aesthetically with AX12 servos.

    So if you want you can use smaller size servos from hobbyking (please suggest) and we can add an additional small PWM servo controller to drive them. :-)

    Julius : "Is it okay if we design different linkages for our humanoid robot?" - yes.
    I have created one robot that uses wires instead of servos directly driving the joints. The structure was completely 3d printed in PLA which makes the robot heavier than it would be should the structure had been done in aluminum. In the page there is a picture showing another example of how a shell can potentially cover the internal structure and make the robot look better. http://goo.gl/DEHPav

    @Limor If you are referring to RoboSavvy Humanoid Design Intel Report, it is not a Challenge entry. It's the only BIOLOID that I could found that looks close to BIOLOID GP with ready CAD files available for download and assembled for reference. It is to help the community better understand how the robot works when it is assembled, rather than guess work. It will also helps kick start more projects since we no need to work from scratch.
    You don't have to worry about the plastic. Many of us here can turn it into sheet metal in a couple of days, if not hours =)

    i was given a bioloid for xmas. i've since donated it to a school, but i noticed it wasn't humanoid at all, apart from standing/walking bipedally. it couldn't transition into a crouch/crawl/kneel. all of these are essential to getting around the human environment. if a robot can't climb stairs, it is basically a cripple. still, that didn't keep bioloid from being a fun toy. are you satisfied with the bioloid functionality? how ambitious do you expect us to be?

    Ypur definition of humanoid: "humanoid implies human like shape and joints. ie: 2 legs, 2 arms."

    Poor Machamp...

    It is a good, wide definition though.

    teigan: "if a robot can't climb stairs, it is basically a cripple" -- crawling is quite a challenging feat for humanoid robots. If you can modify the GP to allow it improved mobility that's great! remember that the knees and feet need to be able to lift the upper structure during the walking gait ; and the great looking exterior shell needs to be there and not impede the movements.

    simonr: "It would be nice to be able to push the functionality - but I don't think that's what this challenge is about" -- the scope of this preliminary period before the actual competition was to get some feedback from the CAD engineering community about how far we can stretch the goals. It would be great to see some interesting structural design innovation. We are concerned about setting the bar too high. The GP is a great starting point and we'd like to see exciting shell designs that may require modifying the metal frame of the GP.

    BTW if you look at the GP, it has a battery pack and a CM510 controller pack. Neither of these are needed for the functioning of the new robot. The controller will be replaced by a RaspberryPi / Beablebone. The battery requirements were mentioned in previous post on this page.

    Regarding the webcam. It can be any miniature webcam that's easily purchased on amazon, ebay, aliexpress, dx.. We have a bunch of "Hama pocket webcam" that are really tiny when stripped off their plastic shell. They are not as easy to source any more. Here's a rough model of the stripped down camera PCB: Hema Pocket Webcam

    I hope you can set the bar much higher, Limor, and give us 2 to 3 months of design lead time with equivalent higher cash prizes and with more slots for cash winners. Almost all of us here are capable of complex kinematics design if you want the meatier aspect of humanoid development. As for me, aesthetics are just skin-deep and there are lots of human resources you can readily tap into that were not necessarily engineers but very skilled artisans/craftsmen and they could even share their designs for free. Also, beauty is in the eye of the beholder, such that any aesthetic design is purely subjective and cannot be fairly judged...

    Hi Limor. I'm glad you set the bar much higher. Yet, considering most of us here have day jobs, few of us have ample time to design a competitive entry in just 30 days. Hope you extend the deadline to allow us to thoroughly explore radical new ideas and bring them into fruition. Perhaps 2 or 3 months would be enough for everybody to participate to such intricate challenge. Any low cost yet astounding design takes months to complete, I think ;)

    3rd Space Challenger by luis.filipe.ferreira.de.moraes-1 (ME lol)

    I can't choose from the other designs, i think all of them have theyr traits and flaws..Many of them are very amazing designs but with not much visual apeal.
    However, i think the choice will be simple depending on how much importance the judges will give to mobility and beauty.

    To all of the entries, Great work. To the finalists, I am honored to be among you. Ann Saint, I think there is more to forwarding humanoid and android reserch than simply making more human like robots.
    Currently building a robot capable of playing robocup soccer will cost somewhere on the order of $12k. While I don't think the finalist's designs are capable of taking on a robot like a darwin-OP, or Nao, by combining a highly capable desktop humanoid with the computing power of the RasberryPi you are greatly reducing the cost of entry into something like a baby humanoid soccer league.
    So instead of $12k a piece, and about $40k for a team of three, you are talking about $12K for a whole team. This puts autonomous humanoid robot soccer in the shooting range of regular high school classrooms. Think of the interest that would generate; the future engineers and roboticists. And that is just one pathway among a myriad of possibilities.
    In anycase, Best of luck to all of you.

    Space Challenger by Luis Filipe Ferreira de Moraes

    RoboSavvy Humanoid Design - unl by Joshua Chung

    RoboSavvy Humanoid Robot V2 by Mohomed Nusry (me) :p

    Comparing those 3 designs, each of them have its own qualities.
    When considering the appearance; UNL stands very high among those 3 designs. But still it may not stick to the proposed cost range. I think manufacturing the UNL will cost more than 10k and will take huge effort. And UNL lacks some required features compared to other two, such as hands with gripping.

    As a conclusion, even the UNL stands top in the department of 'appearance', other two designs(Space challenger and V2) override UNL in the departments of 'cost effectiveness', 'advanced features' and 'ease of manufacture'.

    To partially ecco Mohomed Nusry’s comments cost and buildability were important factors for me in designing the “traditional humanoid” (my design. The brackets used for the most part are sheet metal versions of standard off the shelf bioloid brackets. A prototype of my design could be up and moving around in short order. This also means that users could convert existing bioloid robots into this design inexpensively greatly increasing the user base and availability for users, and creating an environment where a maximum number of individuals are creating software, poses, walk cycles, and so on for the robot. This could be an inexpensive entry into robot soccer, and I would love to see a “baby humanoid soccer league” form which would have similar requirements as robo-cup, but use smaller robots.
    I also included 2 different types of grippers in my design, 1 3D printed, which I have on 2 of my current robots, and work quite well, and the other using bent metal brackets. The use of AX-12s for the grippers was intentional because it gives the user the protection of having thermal shut down, load detection, and so on so that the gripper servos don’t overheat. Better would be a modified clutch system, but that would add costs.
    I also worked to keep my design small and compact minimizing strain on ankle and knee servos.
    There was some concern over using the raspberry pi as a controller and processor, There is potentially room for a small controller to handle poses and motions, and by using a camera system like the havimo you could remove a lot of the CV work from the raspberry pi also.

    Hi all!

    to start I must do my compliments to all the participants for the new ideas and solutions.
    My praises to Robosavvy.com that promoted this challenger because I think this is a good way to diffuse the culture of humanoid robots not only in accademic reality but also in the maker's community.
    Now I must promote my 3D printed humanoid robot; I think that with this solution I met the target proposed from Robosavvy: "make more economic and simple the realization of a humanoid robot".
    For the economic aspect, the cost for a totally 3D printed robot consists of:
    - the cost of all commercial parts like servos, controller, sensors,
    - the cost of raw material for the printer; I estimated about 2 Kilos of ABS (about $ 180 on the Robosavvy store). Sure! you need a 3d printer, but on the internet you can find many that print for third with reasonable prices.
    From the point of view of simplicity, realize my 3D printed humanoid is as simple as clicking on the start 3D printer button.
    The model I posted is still in its infancy because I have not had much time for it, but in the philosophy of the Open-source I think may be a good starting point.
    I think the strengths of my model are the joints of the legs, hands with fingers that can be managed independently, the joints of torso, the use of 3D camera for the view; for the brain I chose the BigleBone Black that I don't know but, on paper, it seems to me the more interesting.
    I also placed the batteries in its feets, in this way the center of gravity of the robot is as much as possible to lower for the benefit of stability.
    In my project I used Robotis AX18 servos for the legs for its high torque.

    Best regards to all

    After looking at the finalists designs, and their personal work, I've come to the conclusion that Che's design is the most viable to work and to be used. It may not be the flashiest but it is darn cute (like a short chubby Iron man). Plus the video was cool. It seems like he has talent and a lot of experience building real robots. I would buy this robot to scare my kids and cats, the grippers are perfectly designed.

These middle and high school students would definitely benefit from access to another robot and seeing their almighty mentor/leader/teacher succeed outside of our puny school community.

  • Chris Farrell

    Chris Farrell 10 months ago

    First of all - looking great guys! Great to see some excellent models and innovation.

    There are three big things I worry about in this challenge, budget (first and foremost), weight (also a pretty big deal with AX series servos), and design complexity.

    To start off - if we consider a robot using mostly AX-12s (at ~40$ each?) - a design with adequete flexibility will take about 7-800$ in servos - leaving the designer with only a few hundred dollars left for the shell and electronics. If we include battery and a rasberry pi, our budget is already nearly finished. Because of this - I would absolutely be looking at the most stripped down a simple robots (cover the metal framework where needed, but try to do so with soft foam or thermoform stuff - nothing heavy, - especially up top). If it were up to me (and the design budget was strict and you wanted it to be easily accomplished) - I would opt for having a robot with no plastic/cover pieces, just have a metal frame with additional holes and a guide for users to design their own frames (or perhaps include different frames as add-ons to the kit).

    I like seeing the designs in CAD (rather than purely 3D models - show me the inner workings!), and while creative ideas (spring in the foot, gears at some joints) are cool - I'm not convinced they would work in real life (the gears remind me of the NAO, and I was never convinced of that part of their linkage). The Spring foot is interesting (One of Pratik's designs), but I fear it would throw walking calculations to the wall (ZMP is designed for flat planes the way it is - never mind stairs and such). I would love to see some videos and some exploration into this though!

    Many of the fully covered bots look too heavy to me, though I like the ones that look very human in proportion (Valerio's MV-02 comes to mind here). The two things I worry about with this design are PLM in the shin (why? - is torque an issue because of all the plastic?), and of course budget (36 servos is huge!). The structure otherwise is tried and true - looks very similar to the Bioloid/Cycloid - so that's good.

    I like the JISSI hollow faceplate/helmet - cool stuff!

    I may be playing favourites, but I quite like Che's Traditional Humanoid design - it is simple, and I believe it would get the job done (and of the simple designs, I believe it is the most human-like - perhaps tied with Space Explorer). I would like to see the backpack hide away a little better, but you've gotta put everything somewhere!). I believe it is one of the only robots that is close to the budget (from my experience) and has low enough weight to be able to pick itself up and also move around and also seems to be near production ready!

    My other picks would be Space Explorer (I would like to see hands on this model :) and the MV-02 (are those shiny pieces plastic, painted metal, anodized? thermoformed stuff?) I would say if you brought the hands down to a single DOF (with a more articulated option perhaps - and same with the head) then you would be much more in the ballpark of the budget. Love the stances.

  • Valerio

    Valerio 10 months ago

    Hi to all!
    It's true! My models are expensive, but I developed the two robots following the philosophy of open-source project. In this way I think to propose a good solution for study, my robots have a big agility (24 DOF for the body), a big flexibility for the manipulation (10 DOF for the hands), an hardware for a good vision system (3D webcam to develop stereoscopic vision system like the solution of DIEGO - http://robotics.oskarpalinko.com/).
    However, it's not necessary to implement all this features; it's possible to use only 1 DOF for each hand, reduce the DOF of trunk; the maker can choose the solution that prefer.
    I also think that the solution more interesting is the 3D printed robot; now it's not complete because I don't have free time to develop.
    A 3D printed solution is easier to make because you don't need a workshop but only a 3D printer on your desk, and if you don't have a 3D printer you can find on-line many 3D printing service.
    I also think that the 3D printed solution is minus expensive.
    About the weight I think that the 3D printed solution can be the more lighter. I started to draw the printed parts like filled parts, and now I'm studying the way to reduce the weight creating gaps in the pieces also useful to run the cables and put the electronic components such as gyroscopes and accelerometers.
    I estimate that at the end the weight of all 3D printed parts will be minus of 2 kilos, with about $180,00 for material cost (ABS).

    As previously stated, Che has a cost effective design; whilst regarding looks it is less sleek than others, the functionality and actuality of it seems far more likely. Particularly if it will be used in education, as an engineering student with interests in robotics myself I feel like this design is very plausible to learn from; there is a certain form of clarity on how each part will function and add to the robot as a whole. Overall it seems to fit a large sum of the requirements quite wellv
