Robots that can recognize pain and repair the two

Advances in the world of artificial intelligence (AI) do not stop, and now scientists at the Nanyang University of Technology in Singapore (NTU Singapore) have been conducting brain-inspired studies to implant in robots the ability to recognize pain and repair themselves when they are harmed.

In this sense, the system designed by the team has sensor nodes that are activated by AI so that they can process and respond to the sensation of pain caused by a physical force when exerting pressure on them.

Also, the system allows the robot to act by detecting and repairing its own damage when it suffers from a minor wound, all without the help of a human being.

Currently, the sensors do not have the capacity to process information, being that it is sent to the central processing unit, a place where learning is generated and that it can involve the installation of a large amount of wiring in the robot body, causing its response to become late.

Also, the robot can present susceptibility to damage that will require maintenance and repair, processes that can involve a lot of time and money.

In the case of sensor nodes developed by the NTU, they integrate AI, connecting in turn with multiple small and lower power processing units, which exercise their function as mini-brains distributed in the robot's skin. This makes it possible for learning to occur locally and helps reduce the robot's response time from 5 to 10 times.

To help the robot learn from harmful stimuli and recognize pain, the research team developed brain-like electronic devices called met transistors, which perform their function by processing memory and information, also acting as artificial pain receptors and synapses.
