| The research team from the University of Tokyo used 3D printing technology to create two very realistic humanoid robots called Kenshiro and Kengoro, doing anthropomorphic activities such as sit-ups, push-ups and stretching.  The research team led by Yuki Asano has been working on humanoid robotics research since 2011 and has made incredible progress in recent years. The new generation of robot Kengoro mimics the human body's very realistic movements, which are based on the human body Skeletal and muscular systems rather than engineering principles, the researchers explained that they used techniques such as 3D printing to adapt the body's musculoskeletal system to aluminum, steel and plastic materials. The robots are equipped with articulated spine (which can bend the upper body), ribs, tendons and joints, and a sensory system that monitors and maintains the balance of the robot.In addition, researchers have integrated brain-like processing modules into the robot, The robot can move and act without direct commands. Kengoro has been in development since 2015 and it even has the power to sweat because it cools the motor by releasing moisture from the porous 3D printed metal Asano explains: 'We used a 3D printer to make a sponge-like metal material for Part of the skeletal structure.We designed a cooling system that allows water to permeate into the material and evaporate. "This means that when a human-sized robot (167cm in height and 56.5kg in weight) is doing a push-up, its motor goes through a A sweat-driven cooling system prevents overheating. Robotic muscles can behave like humans, and they consist of motors, wires and sensors, and researchers can even equip humanoid hands and flexible feet using these technologies and basic systems such as ball and joint connectors. The research team believes that humanoid robots will enable researchers to better understand how the body behaves and move during exercise to create more advanced prostheses.Other potential uses for robotic technology include the development of more advanced crash test prostheses, As well as providing humanoid scaffolds for human tissue transplantation, the team's study has been published in Science Robotics.
