A robot was equipped with a new type of tactile sensor built to mimic the human fingertip. Imitating human strategies, it also used a newly designed algorithm to make decisions about how to explore the outside world.

Capable of other human sensations, the sensor can also tell where and in which direction forces are applied to the fingertip and even the thermal properties of an object being touched.

As the finger slides over a textured surface, the skin vibrates in characteristic ways. These vibrations are detected by a hydrophone inside the bone-like core of the finger.
