IIT and UdG work with new capabilities to perform a robust valve Turning

From the 28th of November to the 5th of December, researchers from Istituto Italiano di Tecnologia (IIT) came to the University of Girona (UdG) to do different tests to develop a successful valve turning.

During this short period of time the two teams have worked together in two different tasks: First, the integration and testing of the new end-effector. Second, testing the Reactive Fuzzy Decision Maker (RFDM) to evaluate the safety of the valve turning.

New end-effector designed to improve the quality of the grasping and equipped with a camera in hand and a Force Torque sensor.

The new end-effector has been designed in three different parts: First the shape of the passive gripper to grasp the valve handle, second a camera installed inside the center of the end-effector to see the manipulated elementa and third a Force/Torque sensor to evaluate the quality of the grasping and the torque needed to turn the valve.

An external thruster has been install in the valve turning scenario in order to add perturbations during the manipulation task. The perturbations effect the valve turning and thus allow to detect the parameters to evaluate the safety. Furthermore, the communication between the RFDM and the Learning by Demonstration reproductor has been tested.
