  • FAIR ReSkin: Artificial skin for robots

    FAIR presented ReSkin, a material with sensors that measure the location of contact with an object and the amount of force applied. ReSkin is planned to be used for robots to perform actions that require high accuracy.
    To date, robots effectively use audio and video sensors to interact with the outside world, but their lack of touch limits the class of tasks that the robot can perform. ReSkin, developed by FAIR in collaboration with Carnegie Mellon University, uses the principle of magnetic sensing, which together with the algorithm of teaching without a teacher allows you to solve this problem. FAIR also posted documentation, code, and several models for ReSkin to be used by third-party developers.
    ReSkin is a polymer with embedded magnetic particles. The change in magnetic signals during polymer deformation, read using magnetometers and analyzed by a neural network, is converted into information such as the location of the contact and the magnitude of the applied force.
    Robots with ReSkin will be able to perform tasks that require high sensitivity, including interaction with small, soft or fragile objects. FAIR suggests that in the future ReSkin will allow robots to perform medical manipulations.
    The cost of ReSkin is less than $6 per 100 units. The material has a thickness of 2-3 mm and can be used for more than 50,000 types of interactions, has a temporal resolution of up to 400 Hz and a spatial resolution of 1 mm. ReSkin can also provide high-frequency three-dimensional tactile signals for quick manipulations such as sliding, throwing, catching and popping.
