Robochallenge 2015 in Vienna featured a free-for-all with 18 robots going against each other in the same ring- the last one standing wins! The actual battle begins about 2:30 into the video, but the introduction of each robot first is kinda cute.
Robots get wrecked, flipped, and thrown completely out of the ring! I was totally distracted by Wedgie, valiantly trying to turn himself upright. Can you guess which one wins in the end? -via Digg
