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

Check out GrabCAD tutorial section for helpful hints in getting started with designing.
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.
