Swiss scientists have developed a third arm that can be used to control the stomach

This project is not aimed at creating a full-fledged third robotic arm. There is no need for it, but there is an urgent need to understand how the human brain works with non-standard tools, how it learns. Scientists want to know if humans can be taught to live in a body other than the one given to them by nature, to adapt to different situations. Again, this research will support the creation of exoskeletons and specialized devices for the disabled.
