Sensorless Force Estimation for Robots with Friction

This paper describes a method for estimating forces applied at the end effector of a robot without the need for force sensors. Servo motor currents and positions are used together with an accurate system model to estimate applied forces. The system model includes inertia, friction and position dependent force components. The signal processing techniques required to extract the force information...

Force-Sensorless Friction and Gravity Compensation for Robots

In this paper we present two controllers for robots that combine terms for the compensation of gravity forces, and the forces of friction of motors and gearboxes. The Low-Friction Zero-Gravity controller allows a guidance of the robot without effort, allowing small friction forces to reduce the free robot motion. It can serve to aid users providing kinesthetic demonstrations while programming b...

Force-Sensorless and Bimanual Human-Robot Comanipulation

This paper demonstrates the iTaSC approach to a force-sensorless and bimanual human-robot comanipulation task on a tree-structured robot, comprising (i) co-manipulation of an object with a person, (ii) dynamic and static obstacle avoidance with its base, (iii) maintaining visual contact with the operator, and (iv) unnatural pose prevention. The task is implemented in a structured way in a reusa...

Friction Compensation for an Industrial Hydraulic Robot

oint friction is one of the major limitations in performing high J precision manipulation tasks. It affects both static and dynamic performances, and may cause instability when coupled to position or force feedback control. Thus, compensating for joint friction has been one of the main research issues in robot design and control over the years. The aim of this paper is to show how friction comp...

A two-wheeled inverted pendulum robot with friction compensation

This paper introduces a method of design and implementation of a two-wheeled inverted pendulum (TWIP) robot with friction compensation. Friction in the drive mechanism is a critical factor of robot self-balancing and affects its performance. The friction parameters are identified based on the dynamic model of the drive mechanism. The dynamics of the whole robot system are obtained by the Lagran...
