Robots Love JavaScript (too)
summary
Argues that a hierarchical state machine is the right model, shows a CoffeeScript/JavaScript framework that injects announcer events into a behavior stack, and actually drives robots. Reverses the Wi‑Fi racer protocol, uses TCP/UDP sockets on a Firefox OS Flame phone, integrates a SparkFun Bluetooth car via a shell netcat hack, and runs a BeagleBone message queue for multiplayer GPS‑flag games. Compass readings prove noisy, steering needs heuristics, the system works enough to run and crash once, and the queue/messages are trivially spoofable.
