Want to design and make your own tools for FarmBot? Follow these instructions to ensure compatibility with the universal tool mount (UTM), the tool bay, and your FarmBot’s electronics.

At your own risk

Building your own tools that utilize the electrical contacts of the UTM could result in damage if improperly designed. Proceed at your own risk. If you would like help building custom tools, consider posting in the community forum.

Unlimited possibilites

These specs must be followed to ensure your tool works with a stock FarmBot. However, don’t shy away from experimentation and the possibility of modifying your UTM, tool bay, or electronics to accommodate your desired tool design. FarmBot is yours to play with and modify!

Hardware requirements

Design your tools to meet these hardware specifications to ensure compatibility with FarmBot. Additionally you will need to design your tool so that it can be produced with available tools, processes, and materials; and stand up to the outdoor environment and other expected stresses.

Required components

  • Plastic “tool base”
  • Three 15 x 5 x 5 mm ring magnets secured with M5 screws and locknuts
  • Two M3 electrical screws and locknuts, and a jumper link used for tool verification

Specs

  • Max weight: 1 kg
  • Max height: 200 mm
  • Max diameter: 100 mm

Size, shape, and layout

Tools must have the correct physical dimensions and component layout on the top face so that they can correctly couple and de-couple with the UTM as well as slide in and out of the tool bay.
