From scratchduino
ScratchDuino is an educational open source robot-designing kit. It is a complete solution, which combines both hardware and software in a single extendable setup. The hardware part is modular and easy to assemble. You can easily build a robot from scratch just combining the motorized platform and different types of sensors. The basic kit includes 2 light sensors, 2 contact sensors, 2 reflective object sensors and an infrared eye. Sensor modules are magnetic-mount, allowing for fast and easy reconfiguration and customization of the robot. Up to 5 sensors can be attached to the platform simultaneously.
