ARTIFICIAL skin embedded with optical sensors could help robots develop a more human touch. Existing sensors, such as those based on simple pressure switches and motor resistance, are limited in ...

He converted an optical mouse into an odometry sensor, making for a very easy way to tell how far a robot has traveled regardless of wheels slipping or motors stalling. The build began with a very ...

This glove can detect when it is bent, stretched or put under pressure A touch-sensitive glove made from stretchable fibre-optic sensors could be used in robotics, sport and medicine. “We made a ...

An optical sensor that measures hydraulic pressure in the landing gear of a commercial aeroplane has been developed by the UK-based company Druck. Based on low-coherence-light interferometry, the ...
