README
README.mdMote
The low cost, high reliability mobile robot for hands-on robotics education.
Motivation
Robotics is more fun with real hardware.
"Low cost" robots are prohibitively expensive for aspiring engineers. We believe robotics should be affordable, enjoyable, and obtainable. So we made Mote.
History
Mote is the spiritual successor of the Little Red Rover project.
For the past two years, Little Red Rover has been used to teach the Foundations of Robotics course at Cornell University. Mote is the product of the many lessons learned during that effort.

Questions
How big is the Mote hardware PCB?
It measures 93.6 × 102.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Mote hardware use?
75 parts, built around the DRV8833PW, TPD2E2U06DCK, USBLC6-2SC6 and LSM6DS3. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Mote hardware KiCad files?
From the empriselab/mote repository on GitHub, at the commit this page was made from: the board is mote-hardware/mote-hardware.kicad_pcb and its schematic mote-hardware/imu.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Mote hardware design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
