Polish engineers have developed a robotic arm that looks like a human
A robotic arm that looks like a non-human, both externally and internally, was developed by Polish engineers. The project was implemented as part of the creation of a robot that is as close as possible to the appearance of a person.
A working prototype simulates the work of the forearm and hand. The development moves the fingers, flexes and unbends them. A robotic arm can make circular movements with a hand, grasping movements. In the example in the video, a hand grasps a dumbbell and tries to lift it.
The development is based on the use of a pneumatic system that operates under the pressure of compressed air and water. Each muscle was visualized by means of a stretchable sealed tube covered with a special braided material. Water is supplied to the muscles through a pump, which is driven by a special valve.
The robotic arm weighs 1 kg and the power consumption is about 200 W.
The engineers covered the prototype of the hand with a translucent material that imitates human skin. This is not only acceptable from the point of view of aesthetics, but also helps to examine in detail the movement of each muscle and tendon.
Polish engineers still have a lot to solve. Now the robotic hand is inferior to the human in terms of grip strength, mobility in the wrist. There are also problems with the software.
In the subsection "Medical equipment and goods for health" there are lots of relevant topics - measuring instruments, hygiene items, mobility aids, etc.
