Simple tank robot with ESP8266 and WebSockets :)
I had an old SRV-1 Surveyor Robot laying around and decided I wanted to update it with more modern tech. The aluminum chassis, motors, tank treads, and 7.5v lipo were all in great shape and ripe for reuse. I opted for the Wemos D1 Mini as the base as they're low-power, resilient, and easy to use.
The sketch sets up web and websocket servers that allows you to control the robot via a tidy, mobile-friendly, web ui.
Motion control is very basic (forward, backward, rotate left, rotate right, stop), but could easily be expanded. Check out the robot in action here.
Detailed instructions for hardware setup, software installation, and operation are available in the wiki
