Researchers from Carnegie Mellon University’s Robotics Institute have developed a technology called RobotSweater, a machine-knitted textile “skin” that enables robots to perceive touch and pressure. This technology is tailored to fit robots with uneven three-dimensional surfaces, and provides a new dimension of sensitivity to robots, allowing them to detect any possible collisions. The RobotSweater’s textile skin consists of two layers of conductive yarn made with metallic fibers for electrical conductivity, and a lace-patterned, net-like layer.
