CNC Beehive for Citizen Science

Medium

Create a new CNC beehive that is designed for sensor integration and scientific observation.

About this Challenge

Total annual losses of bee colonies in the United States were at 42% in 2015. We need to create a public science program to study why this is happening, so we can identify the causes, make societal changes, and help our pollinator friends recover as quickly as possible. Your design will help us create an optimized hive for scientific study.

The goal of this challenge is to design an open source, CNC beehive that accounts for electronic sensor integration, including microphones and sensor probes. It should accommodate wireless data transmission, solar power and battery, as well as allow for observation without requiring that the bees be disturbed.

What makes for a good beehive? As Beekeepingnaturally.com states, “In a natural bee-centred approach, bees are allowed to construct natural comb, thereby determining their own cell size, population mix, colony size, and rear their own queens and drones.”

Judging Criteria

In your design make sure to use effective CNC joinery that won’t fall apart easily, that endures well in the elements, that can be produced efficiently without excessive CNC milling service costs, and that meets the technical requirements for manufacturing listed in the technical requirements section.

The positioning of the sensors is a critical element to keep in mind for your design. We will judge the entries on 1) how well do the sensors integrate seamlessly and non-intrusively into the hive, 2) can beekeepers access the sensors without disturbing the bees, and 3) are the sensors positioned well to gather data without interference from the bees themselves?

Open Beehive Project has developed a special sensor package that will be used to monitor the bees. The sensor package includes a MEMS microphone that will be used to detect hive states based on the audio signal. It should be positioned so it can gather a global signal. Within the core sensor case, there will be a temperature/humidity sensor that is used for gathering data about the ambient conditions around the hive. The package also includes a wired temperature/humidity probe that will be placed in the center of the colony, an external antenna for sending data to a server via WiFI, and a solar power kit that should mount on the roof. The sensor package dimentions are given below in the "Technical Requrements" section.

The estetics of the beehive is another critical elements to keep in mind. After all, more and more beehives are used in urban bee keeping. To make sure your design is accepted by beekeepers as well as bees, aim to achieve a modern urban aesthetic that will situate well on rooftops, patios, backyards, or in community gardens and that makes it easy for beekeepers to care for the colony following natural beekeeping practices. Take look at the image below for some inspiration.

Requirements

  • Your entry must include: 1. STEP files 2. Native CAD files in any format 3. Renderings 4. STLs oriented for printing

  • Technical requirements: Must fulfill design considerations stated above: 1. Manufactured from no more than a single sheet of material (48in x 96in x ½in). 2. Flat end milling bit of no larger than ⅜” 3. Top bar frames (no artificial combs or frames) - natural beekeeping 4. Observation window that can be covered with a panel made from the same material as the rest of the hive. 5. No small loose parts (wedged mortise and tenon). 6. Sensor kit should be protected from propolisation by the bees. The plastic sensor enclosure is 3.75” L x 1.5” W x 1.5” H, and the solar panel is 8in x 12in. The sensor probe is attached to an 8” cable with a 1.5” L x 0.5” W probe on the end that will be inserted into the center of the hive. 7. The milling bit can only cut at 90 degree angles. 8. Only one side of the material can be milled.

  • Additional Design Considerations: Submissions will be judged against technical criteria as well supporting assembly and printing documentation. Ease of assembly, total cost, and print time will also be evaluated.

  • Judging criteria: Judges will weigh a variety of factors but will place special attention upon the following:
    Use effective CNC joinery that won’t fall apart easily, that endures well in the elements, that can be produced efficiently without excessive CNC milling service costs, and that meets the technical requirements for manufacturing listed in the technical requirements section.

    How well do the sensors integrate seamlessly and non-intrusively into the hive, where beekeepers can access them without disturbing the bees, and so that the sensors can gather data without interference from the bees themselves?

    Achieve a modern, urban aesthetic that will situate well on rooftops, patios, backyards, or in community gardens and that makes it easy for beekeepers to care for the colony following natural beekeeping practices.

    Hi Winston Jennings,
    This hive can stand alone and does not need to be compatible with existing Langstroth dimensions.
    The sensor kit is described in the Technical Requirements section, and it is a small plastic case with wired probes extending outward. There are wires connecting a solar panel as well.
    Thanks for the questions,
    Aaron

    My dad kept beehives in the mid-late 80's. I loved it, things have changed so much since then from what I am reading here ! I hope a solution to help the honey bee is found. Is the problem you look to solve to stop the bees from swarming and finding a new ''hive'' or is the existing hive dying out? just curious.

    Why does print time matter as a judging criteria if it's used only as a prototype to visualize how it looks in a cnc joinery challenge? Also, can we use intricate engraved patterns in our designs to help with the aesthetics? If so, what's the minimum tool size?

  • Aaron Makaruk

    Aaron Makaruk about 2 years ago

    Winston Jennings If you can optimize the production process, then that makes the hive more accessible to the general public, since routing services charge by the minute or inch traveled. Find that balance between function and efficiency, and as far as aesthetics go, feel free to engrave, yes, but remember only on one side of the sheet. Thanks

    Bees are likely very sensitive to electronics. Hopefully a high degree of isolation is being used to keep interference to an extreme minimum. Otherwise the bee houses will likely be a flop (and give bad data). A fine Farraday Cage Insulated transmission cables and probably grounding of the cage. It should be pretty close to dead electrically like a normal hive is.

    http://www.omega.com/prodinfo/rtd.html
    The sensor active time is very low by design. Having a brief sampling system rather than an always on system might be useful in not disturbing the bees.

    I love the spreading of information and enthusiasm, but we already know why all of the bees are dying. Monsanto and their pesticides/herbicides are the main problem. Research over the years has proven that one of the main chemicals called neonicotinoids is killing the bees. If one bee comes in contact with it and returns to the colony they all usually die. Monsanto has been killing our planet slowly with these chemicals and destroying us as well as other countries with GMOs. Then if you research Monsanto they act like they're trying to help the bees..so sad.

    With a given thickness (1/2 inch) and the size of the material is very difficult to create a design for all climatic zones. In the northern latitudes during the winter more. The smaller wall thickness of the hive, the greater the feed rate of the bees. During prolonged wintering feed may not be enough. Under natural conditions, the bees live in tree holes with a wall thickness of the hollow 30 ... 100 mm (1,5...4 inch)...

We'll take the winning design and make a parametric model, so there will be variations available in metric and imperial units, with different sheet thickness and tool size combinations - everyone will have what they need for their unique circumstances.

    For winter you can use a double-walled beehive, but then you need more m2 than one sheet.
    I remember that my grandfather used in Estonia (winter ~ -30°) 25mm wood + 75mm sawdust+ 25mm wood for walls and on top was some pillows. I don't know what kind of nowadays synthetic material is acceptable for bees.

    The thickness of the walls of the hive is not very critical for wintering bees. However, the smaller the wall the more bees consume energy for heating. The danger is that the defunct point may not have enough honey. Another factor - the bees calm. Excited bees also consume a lot of honey. The instinct of bees laid feed salvation. Therefore, when any danger they take with them a little more honey. For warming You can use a sandwich of materials. The main thing to observe a condition - the material from which the contact should be a natural bee.

    Two small remarks regarding the conditions of challenge (in my humble opinion):
    1. For cutting the sheet at an angle of 90 degrees using a laser is cheaper and faster.
    2. Are all the long history of beekeeping can be ignored? Is the size and proportions of the beehive are selected from the condition sensors placement?
    If not enough participants, it means that something is wrong.

    What a disaster. My laptop crashed and is not usable anymore! I had my inital drafts and designs with no backup. Really dissapointed. I do not have enough time to get everything to where it was. Good luck to the others. :(

    @Solid Tweaks you might be able to save your data files if it's just the operating system that's toast. You will unfortunately need a laptop HDD enclosure or a usb converter and you will need to remove the old HDD from your laptop without damaging. This is done by slaving the drive and making it an extra drive in another pc. Careful what you transfer if things are actually corrupted you wouldn't want to copy whole programs just your documents and models etc. There are videos on how to do this in more detail.

    @Nathaniel Andresmooi - Yes, it looks like there was a typo as it should be a co-founder of Naturebytes. Very much looking forward to helping review all of the designs shortly.

    @Nathaniel Andresmooi Thanks for the tips. It looks like my HDD is dead. checkdisk does not work and OS loading takes forever. I even tried working with another computer only to extract data. To copy a word file of 1MB takes likes hours. The hard disk is accessible one minute and is not the next minute. It has killed all the excitement I had, this weekend. Maybe next time.

    this platform with it's challenges is turning into a joke. Seems like nobody cares about rules and deadlines here anymore. Finalists are being selected randomly and announced whenever. Lack of communication between GrabCAD team and designers makes it even worse. I have not participated in any challenges for a while now because I don't think it's worth my time but I visit this site ones in a while to see if things are improving. Guess what... Looks like everything is going south instead. I think the idea of this website is great but execution is getting terrible at the best. Looking forward to see a startup with similar idea but with serious people behind it that cares about what they do. I'm sure it would bring much more and better designs than this joke.

    I understand that somtimes things take longer than expected and there is probably a good reason why the winners have not been announced jet. An update would be very nice however.

    Ben Ewing what happen to the Grabcad community? These challenges were taken seriously before and we got regular feedback from the people at Grabcad.

    @Philip LaRoach It's possible the more active forum mods and posters are just busy with multiple things and GRABCAD is just feeling neglected in the posting department. They might need to add some forum people?
