a1rb4Ck / esp8266-wifi-car

2WD wifi car with front sonars, using an ESP8266 for communication to an external brain. Reinforcement learning to train obstacle avoidance in a simulation, then applied on the real car.

ESP8266 WiFi car

Firmware for the ESP8266/NodeMCU WiFi car.
Embedded web server to live stream sonars sensors values via WebSockets.
Optimised web contents on the SPIFFS flash.
Towards Reinforcement Learning to learn an obstacle avoidance algorithm in simulation, then apply it on the real car.
It will be used as teaching material for an Applied Machine Learning engineering course.
