CTOnews.com May 4 news, the development of robot technology has always been a hot topic of human exploration. How to make robots more like human beings, not only in appearance, but also in function, is the pursuit of many scientists. Recently, researchers at the Bionic Robotics Laboratory at the University of Cambridge have made important progress in developing a hydrogel-based robot skin that simulates human tactile perception, opening up new possibilities for the development of robotics.

CTOnews.com note: the hydrogel created by the researchers in the damage detection experiment is a kind of gel that is insoluble in water but contains a lot of water, with good flexibility and biocompatibility. The team used hydrogel to make a highly stretchable skin material, combined with resistance layer measurement technology, to obtain information about the state of the skin by installing electrodes at the edges of the skin, applying electric current and measuring voltage. This information can be used to determine whether the skin has been touched or damaged, as well as the location and strength of the touch.

Different from the traditional artificial skin system based on neural network, this kind of hydrogel robot skin does not need a complex computational model to analyze the electrode data, but uses a simplified method based on a small amount of real data to generate the deformation graph. In a preliminary assessment, they found that their system was significantly better than the artificial skin system based on traditional neural networks, achieving an average resolution of 12.1 mm on 170 mm round skin.

The research team conducted three practical tests on the hydrogel robot skin, namely, damage detection, environmental monitoring and tactile stimulus recognition. Their systems perform well in all three tasks, suggesting that they can be used to improve the capabilities of software robot systems designed to handle different tasks.

The research team says they are currently improving the shape and size of the skin so that it can sense more complex stimuli. For example, if skin is applied to a robot's hand, they want it to sense not only the position and strength of the touch, but also the position of each finger and whether the hand is damaged.

The findings have been published in the journal Electronic Materials Today.
