Ruby Robotics
summary
Survey shows concrete tools and working demos: JRuby on Android + DRb to call Ruby methods over the network, controlling GPIO on a Raspberry Pi; Sphero and Parrot AR Drone via artoo.io used for quick wins (Sphero sometimes finicky but demos mostly succeed); analog RGB solved with pi‑blaster software PWM (multiplexes one hardware PWM into eight); full RC tank built with Raspberry Pi, 12V battery and Sabertooth 2x12 motor controller, motor reversal fixed in software, remote control at ~20 Hz sampling.
