The temperature inside the JET nuclear fusion reactor exceeds 100,000,000°C, so physicists use a robotic arm system to manipulate, check and repair equipment inside.

These robotic arms are controlled remotely by an operator in the control room. He can see what he is doing through visual cues on video monitors, but he can also ‘feel’ his way around the reactor, using a force feedback system.

Classroom Ideas

Could be used as a starting point for a discussion on the advantages of using robots in situations where humans would not be safe. Could also be used to highlight the advantages of remote control engineering systems. Pupils could also discuss where technology might lead in the future and how robots such as this might be developed for other purposes.
