Video: Robot actually hits people when they get hit in VR game

Robotics engineer and YouTuber James Bruton, along with UK's Portsmouth University students, has co-developed a robot that fights humans in real life while they're playing a custom-made Virtual Reality (VR) game. The robot, mounted on a wooden base, is made with 3D-printed parts and foot pumps. Trackers in the room track the robot's arms and player's headsets and foam bat.
