Abstract:
A Model-Based, Whole-Body Motion-Control (WBMC) system for an articulated robot required to perform simultaneous tasks which are not prioritized a priori and which may also be competing, the system comprising is described, the system comprising : • one or more attractors (MinEff, MomJ, MomCOM, JLim, EEff ), each of which is an operationally independent closed-loop, model-based torque/ force-control module associated with a corresponding robot's controlled task, and is designed to receive a quantity computed based on one or more quantities ( q, q ) representing the state of the robot, and to output robot's joint torques (TGC,TME, TMJ, TLMC, TAMC, TJL, TEE ) which are to be applied to robot's active joints to attract the robot's current state to a robot's target state; and • a torque and/or linear force command generator designed to receive the robot's joint torques and/or linear forces from the one or more attractors and to generate a torque and/or linear force command for the robot based on the received robot's joint torques to cause the robot's current state to converge to the robot's target state.
Abstract:
An electronic measurement unit for a polymorphous device (1), comprising a number of lateral structures (4), each lateral structure including: a support structure (8, 10, 22, 26, 28); at least one sensor (12, 14) constrained to the support structure and generating an electrical signal indicative of a deformation of the support structure; and a coupling structure (42) that constrains a corresponding external covering element (40) to the support structure in a releasable manner, so that when the external covering element is constrained to the support structure and an external force acts on the external covering element, the electrical signal is indicative of the external force.
