One of the limiting factors of today's robotic manipulation systems is the problem of
As a step towards improving robotic manipulation, we are introducing DIGIT, a low-cost, compact, high-resolution tactile sensor designed to improve the robotic arm manipulation process.Quote from a scientific article
Sensor developed by a team of researchers inFacebook is powered by touch technology developed in the past. The sensor is small and can be mounted on a robotic arm with several fingers.
In order to evaluate the performance of DIGIT, the researchers applied a sensor to each of the fingers on the Allegro robotic arm, a multi-fingered hand developed by Simlab that is often used to test new methods for manipulating objects.During the experiment, the team trained a neural network model to act as a controllerfor the Allegro hand: the robotic hand moved the glass beads.
In these tests, the sensor worked well, it collected high-resolution haptic data that could be used to train deep neural networks to better control the Allegro hand .
In the future, researchers plan to continue working on the sensor, they want to make its size even smaller, and also include curved omnidirectional sensitive fields in it.
