Robodog uses magnetic 'paws' to CLIMB up walls and across ceilings

The fear of killer robots dominating human civilization is one step closer to reality with a new robotdog that climbs up walls and across ceilings. Developed at the Korea Advanced Institute of Science and Technology, the MARVEL quadrupedal robot features magnetic feet that magnetize and demagnetize on demand. Switching between the two settings allows the robot to keep one foot attached to the wall or ceiling while releasing the other to the next spot. It moves 1.6 feet per second while climbing up a wall and two feet per second when traveling across the ceiling. MARVEL may seem more like the killer robodog in Black Mirror, but its inventors foresee the innovation helping repair bridges, industrial tanks and buildings.
