The robot arms from KUKA Robotics can be used for more than just factory automation. The fine folks at UCLA recently showed how they use a KUKA robot arm to simulate the extreme forces athletes’ knees endure, helping researchers better understand how the knee works, how it gets injured and how best to repair it.

The Geek Group, a non-profit science and technology educational organization, has come up with a new use for KUKA robot arms: destroying old cathode ray tube (CRT) TVs.

Maybe it’s because CRT TVs are so darn heavy and impossible to move, but there’s something satisfying about watching the KUKA arm absolutely annihilate these TVs.

The video really demonstrates the brute force behind a KUKA arm, smashing the TVs into smithereens.

The Geek Group a long time ago named its KUKA robot arm “Jeff.” And it’s no coincidence that The Geek Group’s next video shows them giving Jeff some TLC after all his hard work.
