These Robot Siblings Can Sweat Like Humans


Kenshiro and his younger sibling, Kengoro can do sit-ups, push-ups, stretches and they sweat. However, they are not humans but humanoid robots built with unprecedented similarity to human anatomy, thanks to a group of scientists and students from the University of Tokyo.They have a unique design that allows them to move in ways looking closer to natural human movement than any preceding robot.

In terms of the design principles of the human mimetic humanoid, its design is centred around four key areas—body proportion, skeletal structure, muscle arrangement, and joint performance stated in the paper published in Science Robotics. Kenshiro is the first humanoid developed based on the concept followed by Kengoro , another robot that was developed with a lot of improvements for a higher degree of fidelity to humans.

Kengoro is built with the structure that closely mimics the human anatomy.It has a muscular-skeletal system including joints and tendon like parts.In addition to that, to monitor balance and stability, it has a sensory nervous system from implanted sensors on its body. It has brain-like information processing capabilities that allow it to use existing data to act without explicitly being told what to do.

The machinery that allows the robot to move like a human heats up, requiring water to circulate through its metal frame to cool it. Steam vents through holes in the skeleton to accomplish the cooling. The engineers created these two cousin robots with an intention to study human movements in greater detail for athletics and aided development of artificial limbs.

But these human memetic humanoids can be used for active crash test dummies used during car crash testing because current dummies can only measure passive behaviour.One research group has suggested the possibility that a musculoskeletal humanoid can be used in medicine, such as to grow tissue grafts.

The research team has successfully developed musculoskeletal robots and it seems possible to use these to the stated purpose because they imitate the human musculoskeletal structure, support the flexible body and behaviour of humans, and support human-style muscle actuation using tendon-driven actuators
