An open robot shield for Arduino
Open Electronics‘ staff were looking for a common and standard hardware platform usable on different robots they were working on. Their goal was to find a single platform that had to provide power supply to the microcontroller, it had to provide stabilized voltage for the servos, and, finally, it had to be equipped with an obstacle detector and with an IR receiver.
Having chosen Arduino as the target core board, they developed an ad-hoc shield meeting all these requirements, whose detailed description can be found here, together with the BOM and a lot of source code.
