The Linux-based Google Android phone OS is being used on an HTC G1 phone to control Forknife, a strange little robot with articulated cutlery that seems determined to possess snack cakes despite its complete inability to eat them. Forknife integrates an Arduino microcontroller with the G1 phone using DTMF tones for communication. The robot also communicates with a desktop computer via WiFi, 3G, or EDGE networks. Jeffrey Nelson created an Android app called RoboComm and a PC-based app called RoboServ to pull this off. He also released the code as free software under the GPL so others can use and improve it. For more, see Jeffrey's explanation of the system and his schematic of the control system. We'd love to see what happens when this G1 robot meets the iPhone robot we reported on a few weeks ago!
