# video | Recycling robot recognizes paper, plastic and metals by touch

Before recycling for reuseuse, you need to sort them by the type of material from which it is made. At the moment, this is done by special workers, and their work is extremely tedious - not only can they get objects with harmful substances, so the work itself is monotonous and boring. Soon, robots can sort out the garbage - at the Laboratory of Artificial Intelligence at the University of Massachusetts they created a structure that can touch the paper garbage from plastic and metal.

The recovery robot was named RoCycle, and itsThe main feature lies in the hands, which, thanks to the sensors, easily determine the material of the object and throw it into the appropriate waste bin. A sensor for measuring surface deformation determines the size of an object, and a device for determining pressure recognizes its fragility. Thanks to them, the robot can recognize easily squeezed paper and more rigid plastic. Metal objects are easily detected - sensors measure the conductivity of a material

Robot hands are made of free stretchingmaterial auxetica. Each of them can perform as a function of both the left and right hand, and performs more dynamic actions than the limbs of other robots. Thanks to this design, the need for air pumps to hold objects completely disappears.

With all this, the RoCycle robot has weakparties. For example, it is able to lift only fixed objects - in this case, the accuracy of capture is 85%. However, if the object moves along a conveyor belt, the accuracy drops sharply to 63%. It may also be that the metal debris is inside the paper bag, and the robot accidentally throws it in the wrong bin.

Researchers intend to correct all these flaws. They believe that the robot needs a computer vision system, so that it works in conjunction with robotic "organs of touch".
