Robot Rumble: Build. Bash. Repeat.

Robot Rumble is an interactive project, where spectators can battle remote-controlled robots, made purely of Obtainium. Built on a mobility scooter base, each robot is made from trash cans, old equipment and random metal parts, attached in a variety of ways.

The robots are extremely nimble, with the ability to go forward, back, turn or spin wildly as parts swing at their opponent. The sound of crashing metal and cheering crowds can be heard, as battles are fought. Meanwhile, the Obtainium Works crew rebuilds the next robots from those previously bashed.
