__KC01__ (AKA "Kaycee Oh-One", for the ''__K__iwiBot __C__ircuitPlayground Model __1__'') is a ["mini" sized|RobotWeightClasses] robot that without batteries weighs only 163 grams. It's currently an unfinished design and has no sensors, but it has ''plenty of possibilities'' in this regard. See below.
__KC01__ (AKA "Kaycee Oh-One", for the ''__K__iwiBot __C__ircuitPlayground Model __1__'') is a ["mini" sized|RobotWeightClasses] robot that without batteries weighs only 163 grams. It's currently an unfinished design and has two short-range Sharp infrared sensors, but there are ''plenty of possibilities'' in this regard. See below.

It uses the __Circuit Playground Express__ microcontroller, which is very suitable for people who've never built a robot before, or used a microcontroller. The Circuit Playground board is very useful for non-robot applications as well.

I learned recently of an "improved" version of the CRICKIT board (same form factor) called the [RoverWing|https://roverwing-board.readthedocs.io/en/latest/, which includes PID, an IMU and a more powerful motor controller.

If you want to use odometry, you can __upgrade__ by buying the motor encoders and the motors ''without'' the Push Header Shim (which is incompatible with the motor encoders as they both solder to the same place). You'll want the extended back shaft version.

!! Programming
With the two Sharp infrared sensors, I've written a short program that uses two of the touch sensors to activate a main loop function that performs simple object avoidance: if the left sensor detects something the robot backs up and turns turns right; if the right sensor detects something it backs up and turns left; and if both sensors detect something it just backs up further and turns randomly.
