It's Sumobot fighting time!!
Originally posted for Facebook, this shows the simplebot using the Captain Arguino Arduino board from www.podpi.com being controlled via AJFisher's UDP transparent bridge to Johnny-five over Adafruit Industries' ESP8266 "Huzzah" development board.
This design was adapted from Andrew Fisher's article in Make: JavaScript Robotics by Rick Waldron & Backstop Media.
I control the bot using W, A, S, D.
