CHRP4 Complete Kit

Learn microcontroller programming and build your own line-following, obstacle-sensing, and Sumo robots with the CHRP4 kit. The CHRP4 circuit is an open hardware, open source, robotics-focused variant of our simpler UBMP4 circuit, and was designed specifically for learning or teaching microcontroller programming in C while building robots!

Get everything you need to build the brains of both a line-following robot as well as an obstacle-sensing/Sumo robot in our complete kit, including all of the on-board parts, an ultrasonic distance sensor, and all of the LEDS and phototransistors needed to populate all three of the break-away line and floor sensor modules. Refer to the CHRP4 page for complete schematics, lesson activities, and other resources.
