...Before it's too late.
Robots duking it out in public is nothing new; shows like Robot Wars and Battle Bots popularized this form of mechanized combat all the way back in the early 2000s.

Tech blogger, Robert McGregor, cut together a highlight reel of footage shot over several years of these squirrelly little robots shoving each other around a tiny ring like a pair of feral cats, and my shins hurt just looking at 'em. According to Motherboard, this Robot Sumo competition "highlights mostly autonomous matches, showing off the small, 3Kg-class robots that contain microcontrollers, sensors, and other electronic gadgetry needed to fight to survive inside the ring." And you thought stepping on Lego hurt.
