MIT creates a soft-fingered robotic gripper than could eventually tie knots and sew stitches

MITs Computer Science and Artificial Intelligence Lab (CSAIL) has shared the results of a new project in which it built a two-fingered robotic gripper, which has soft pads for dedicated and fine manipulation of objects like cables, sheets and more. The robots design is based on how humans use their fingers to do things like untangle wires and tie knots.
To do this, the CSAIL research team equipped their robotic gripper with fingertips that are not only made out of a soft material, but that also have embedded sensors which help it continually detect the position of a cable between the grippers to better control holding and manipulating them while performing simple tasks like detangling.
The fingertip sensors provide high-resolution tactile information, using so-called GelSight technology that embeds tiny cameras in soft rubber. These sensors provide data on how the cable is situated between the two fingers of the gripper, and on how much force is being exerted on the cable in terms of friction as it moves between the pads. This allows it to change its pose and grip depending on whats needed to get the cable into the position you want an approximated version of what were doing when we work with cables or cords.
