These are a couple videos of a LinkerBot Linker Hand L30 demonstrating its quickness by screwing a variety of nuts and bolts at lightning speed. It’s like a cordless screwdriver…but a hand. Talk about fingers of fury! Is this a pleasure model? If it isn’t already, it will be soon.

This is a video demonstration of the Roadrunner bipedal robot developed by the Robotics and AI Institute. The 33-pound robot looks like a pair of dismembered robotic legs with wheels for feet, presumably because that’s exactly what it is. It can roll around with its wheels oriented straight ahead or

Electricity: it’s terrifying. And to prove that point, this is a video of electrical engineer Greg Leyh turning one of his giant Tesla coils (because who can have just one?) into a targeted high-voltage plasma cannon. It’s like a mini Death Star. He then tests the ray on a model

This is a video from the fun/danger-loving crew DD Squad (I’m part of a small B Squad myself) using a custom built rig to launch a human at 50MPH from the rear of a truck traveling at 50MPH so that he can just stand the landing, since 50MPH – 50MPH
