Robots that act like ants. Robotics engineers at the University of Notre Dame have created multi-footed robots capable of cooperative behavior in complex environments. This modern robots can successfully navigate rugged terrain and get to difficult places. Engineers have printed robot ant parts using 3D printing The size of the robots reaches 20 centimeters. The small four-legged constructions can communicate with each other and solve problems together. The parts of the device were printed using a 3D printer. The designers equipped the mechanical insects with a lithium polymer battery, a microprocessor, magnetic touch sensors on the front and back, and a light sensor on the front. Each device has four flexible legs that help it navigate over difficult surfaces. According to the scientists, the robots on the legs are able to move in difficult conditions, including hard-to-reach places. The limbs are used to effectively support the body.
