Download CAD Files

You can download the above CAD assembly for your own personal use. I only ask that you understand and agree to the following:

  • This is a work in progress and is not a completed design. Conceptually, everything works (as is shown in the video), but there are many areas of the design that may need improvement in order to sufficiently control a robot.

  • If you use this design or modify it, please let me know about it. I'd love to see your work! Also, please give me credit for the design when possible.

  • Finally, please do not use this design for commercial purposes.
