Distributed Robots with Elixir
summary
Repositories show Sphero and Parrot ports lifted from Ruby into Elixir using structs/maps and gen_server clients that emit serial or UDP bitstreams. An Android app uses Android via JInterface by packaging an Erlang runtime, launching epmd (copy step ~7 minutes) and sending gen_cast tuples to remote nodes. A Raspberry Pi runs GPIO code with Pi Blaster PWM for eight software PWM channels, drives an RGB LED and a Sabertooth‑controlled RC tank ( -1..1 → 1000–2000µs). Demos mostly work but suffer network drops and a reversed motor wiring fixed in software.
