This is one of the most satisfying kits I’ve ever built, and the Sumovore it creates will be eligible for official RoboGames Mini-Sumo competitions, in which robots vie to push each other out of the ring.

It ships with analog “discrete brain” circuitry, but “brainboard” kits let you add popular microcontrollers.
