Kickboxer vs Ruby - the state of MRuby, JRuby..
summary
Build log: a pool-noodle sparring robot is implemented with two actuators driven by an ESP32, using ESP32 with MRuby on-device but requiring copying C project files and the ESP‑IDF/Python build chain to flash firmware. Devices publish via Eclipse Mosquitto MQTT with a 5s keepalive; server-side prototype runs on CRuby 3.2.2, JRuby 3.1.4 runs on a laptop with minor terminal tweaks, JRuby crashes on Android, iSH runs Ruby 2.7.8, and a final Android client successfully controls the life‑size robot.
