Japanese researcher's invention can transmit force between two devices

[TOKYO] A Japanese researcher has unveiled an invention that instantly and wirelessly transmits force between two devices, in a development that could allow physical therapists to treat patients remotely.

Kouhei Ohnishi said his "force transceiver" permits two-way communication of the amount of pressure being applied and the resistance it is encountering in real time.

If applied to a robot, for example, it would mean a skilled operator could use the device to remotely carry out complex work in areas where it was not safe for people to be - for example because of high temperatures or radiation.
