The most consecutive push-ups (press-ups) by a life-size humanoid robot is five, achieved by the University of Tokyo's 167-cm-tall (5-ft 5-in) biomimetic robot Kengoro in 2016. The feat was performed as part of a test of Kengoro's evaporative cooling system and the results presented at the International Conference on Intelligent Robots and Systems in Daejeon, South Korea, on 15 October 2016.
Kengoro's physical feats are made possible by its unique cooling system. Instead of being encumbered with bulky fans or cumbersome liquid-coolant pumps and pipework, Kengoro sweats. Its skeletal frame is 3D printed (using selective laser sintering) to include microscopic channels and pores on the surface. The motors fit snugly into recesses in this 3D-printed skeleton, allowing the heat to be transferred from the motors to the skeleton. Water is then pumped at low pressure through the skeleton, absorbing the excess heat and releasing it through evaporation.
Kengoro has been designed to accurately mirror the capabilities and range of motion of the human body, with 174 degrees of freedom (including 30 in each hand). Its designers aim to make a robot that is both flexible and strong, with hands and feet that are fully articulated while also being strong enough to support the robot's full weight. Having mastered press-ups, it is hoped that Kengoro will soon be able to move on to the pull-up bar.
