MIT's 'blind' robot climbs stairs, senses obstacles by touch
MIT has developed a 'blind' robot called 'Cheetah 3' that can climb stairs and sense obstacles without relying on cameras. Weighing around 40 kg, the robot is equipped with algorithms that help it navigate its environment by touch which the researchers describe as "blind locomotion". Further, the robot can stretch backwards and forwards, and twist from side to side.
