The human forearm is composed of two long, thin bones called the radius and the ulna, and rotates using two axle joints. We aimed to develop a forearm based on the body proportion, weight ratio, muscle arrangement, and joint performance of the human body in order to bring out its benefits. For this, we need to miniaturize the muscle modules. To approach this task, we arranged two muscle motors inside one muscle module, and used the space effectively by utilizing common parts. In addition, we enabled the muscle module to also be used as the bone structure. Moreover, we used miniature motors and developed a way to dissipate the motor heat to the bone structure. Through these approaches, we succeeded in developing a forearm with a radioulnar joint based on the body proportion, weight ratio, muscle arrangement, and joint performance of the human body, while keeping maintainability and reliability. Also, we performed some motions such as soldering, opening a book, turning a screw, and badminton swinging using the benefits of the radioulnar structure, which have not been discussed before, and verified that Kengoro can realize skillful motions using the radioulnar joint like a human.

Very impressive.

How many lights should it have?
YES

This is incredible, i always wondered if a robot could have tendon like kinematics, i am very impressed. The face is a little bit creepy though 😰

It so complicated so it doesn't really work

All the best for destroying universe

Imagine wasting money on the robots while ppl starving good luck the world will end

Advancement in technology helps in a cascading domino effect, this is only a waste of nothing is learned. It is not always immediate how technology helps, but if this advances robotics it is one step closer to creating cheaper better automated machines to assist in positive life saving technology. From better agriculture to saving lives by not risking human life. You should break down the walls in that small box you live in and expand how you view technology in a positive way.
