Baobot is my team's entry into the AFRON Design Competition. It is a 2-wheeled design intended for classroom use as a way to teach middle and high school students about electronics, programming, and robotics.
Baobot is capable of USB tethered control (via serial console) and autonomous control. In autonomous mode, the robot will roam around until one of the whiskers are hit. If a front whisker is hit, the robot backs up, turns left or right, and moves forward again. If a rear whisker is hit while moving backward, the robot moves forward. An optional line following sensor board can be added to the front, which allows the robot to follow a dark line on a light background.
A battery pack (3x AA batteries) can be added as well. The main chassis and battery pack each have 4 small magnets, which allow the battery pack to snap in to place. The battery pack is plugged in to the main board via USB cable, which turns the robot on. Once powered, the robot will begin executing whatever program has been loaded on the microcontroller.
Baobot is based on Sparkfun's Arduino Pro Micro, meaning that it is Arduino compatible.
