The humanoid robot Kengoro is equipped with a massive 108 motors to perform a wide range of functions, including pushups. But those engines can obviously overheat in minutes during such activities, so its Japanese developers have incorporated artificial veins in Kengoro`s 3D printed metal `bones` that cool down the motors using de-ionized water. This robotic breakthrough is from a laboratory at the University of Tokyo.
The ["sweaty solution is also very efficient in terms of weight – unlike most other cooling methods which only increase bulk. And standing 1.7m tall and weighing 56kg already, Kengoro was already absolutely packed with hardware. The team led by professor Masayuki Inaba therefore opted to incorporate the cooling system inside Kengoro`s metal frame, ensuring that no additional weight was added.
