ArduSkyBot v1.0, an open source educational printbot [Git repo]

thingiverse

The MiniSkyBot has been enhanced with an Arduino UNO, Printshield, and CNY70-board. It now features an ultrasonic distance sensor, two light sensors, a line sensor, two buttons, four LEDs, and a piezoelectric speaker. To build your own, print the MiniSkyBot chassis and wheels (using 6 AAA batteries), create a Printshield and CNY70-board from provided designs, modify two servos for continuous rotation, assemble everything, place the speaker behind the board, and program it. More information and testing code can be found on GitHub. Many ideas were taken from MiniSkyBot 2.0 by Obijuan and HKTR-9000. Watch the robot in action at the 2012 Summer Workshop on YouTube. The files are now hosted on GitHub.
