Here is a lifelike humanoid robot modeled after a 13-year old male that can perform push-ups, sit-ups, and other similar moves and “sweats” to keep its motors cool. Kengoro has 116 actuators to pull its wires. As it performs activities, water is circulated through its specially designed metal frame to release heat from the motors.
Kengoro can not only move its head side to side but has a flexible spine. It can stand on its toes, play badminton, and do a whole lot more. The above videos show it in action.
