A method of detecting change in contact between a contact part of a robot arm and an object as defined by the independent claims, by obtaining a contact force provided at the contact part of the robot arm by sensing a force provided to a part of said robot arm; and by obtaining the part acceleration 5 of the contact part of the robot arm by sensing the acceleration of at least a part of the robot arm and then indicate if a change in contact between the contact part of the robot arm and the object has occurred based on the obtained contact force and the obtained contact part.

Detection of change in contact between robot arm and an object

A robot controller for controlling a robot arm includes a first space shaping module configured to provide a shaped first space target motion by convolving a first space target motion with an impulse train, where the first space target motion defines a target motion in a first reference space; a second space shaping module configured to provide a shaped second space target motion by convolving a second target motion with the impulse train; where the second target motion defines the target motion in a second reference space; and a motor controller module to generate motor control signals to the joint motors based on the shaped first space target motion and the shaped second space target motion.

Input shaping control of a robot arm in different reference spaces

Methods includes calibrating robots without the use of external measurement equipment and copying working programs between un-calibrated robots. Both methods utilize the properties of a closed chain and the relative position of the links in the chain in order to update the kinematic models of the robots.

Calibration and programming of robots

The invention pertains to a method of calibrating robots without the use of external measurement equipment. The invention furthermore pertains to a method of copying working programs between un-calibrated robots. Both methods utilize the properties of a closed chain and the relative position of the links in the chain in order to update the kinematic models of the robots.
