Robot That Learns Via Touch

Researchers in Europe have created a robot that uses its body to learn how to think. It is able to learn how to interact with objects by touching them without needing to rely on a massive database of instructions for every object it might encounter. The robot is a product of the Europe-wide PACO-PLUS research project and operates on the principle of “embodied cognition,” which relies on two-way communication between the robot’s sensors in its hands and “eyes” and its processor. Embodied cognition enables AMAR to solve problems that were unforeseen by its programmers, so when faced with a new task it investigates ways of moving or looking at things until the processor makes the required connections.

AMAR has learned to recognize common objects to be found in a kitchen, such as cups of various colors, plates, and boxes of cereal, and it responds to commands to interact with these objects by fetching them or placing them in a dishwasher, for example. One example of the tasks AMAR has learned to carry out is setting a table, and it is able to do this even if a cup is placed in its way. The robot worked out that the cup was in the way, was movable, and would be knocked over if left in the way, and so it moved the cup out of the way before continuing with its task. The type of thinking demonstrated by AMAR mimics the way humans perceive their environment in terms that depend on their ability to interact with it physically.
