The dynamic uncertainties and disturbances characterizing continuum soft robots call for the derivation of simple and possibly information-free controllers. We propose an iterative learning control law for shape regulation of continuum soft robots consisting of a PD action and a feedforward term,...

This paper presents a unified approach to detection and isolation of both actuator faults and unexpected collisions for a two-link robot with a flexible forearm. The proposed approach is sensorless, i.e., no dedicated exteroceptive sensors are considered, and is based on the design of residuals to...

Performing precise, repetitive motions is essential in many robotic and automation systems. Iterative learning con- trol (ILC) allows determining the necessary control command by using a very rough system model to speed up the process. Functional iterative learning control is a novel technique that...

In physical human-robot interaction (pHRI) it is essential to reliably estimate and localize contact forces between the robot and the environment. In this paper, a complete contact detection, isolation, and reaction scheme is presented and tested on a new 6-dof industrial collaborative robot. We...

Soft robots are intrinsically underactuated mechanical systems that operate under uncertainties and disturbances. In these conditions, this letter proposes two versions of PID-like control laws with a saturated integral action for the particularly challenging shape regulation task. The closed-loop...

TITLE: Putting energy and geometry back in robotics
ABSTRACT: Whether fixed to the ground, moving in a room, swimming in water, or flying in air, robots inherently interact with their environment in a bilateral manner. From a system theoretic... -

Abstract
Soft wearable exosuits have been introduced in the last decade as possible candidates to overcome the limitations from devices using rigid structures: the exoskeletons. Despite the Exosuits initially promised tangible improvements, yet their soft wearable...
