Abstract: The present invention relates to a user friendly method for programming a robot, where the method comprises placing the robot at a given position P0 in the surroundings and using a portion or point P of the robot (for instance the point to which a tool is attached during use of the robot) to define one or more geometrical features relative to the surroundings of the robot and establishing a relationship between the geometrical features and first coordinates of a robot-related coordinate system, whereby the robot can subsequently be instructed to carry out movements of specified portions of the robot relative to said surroundings by reference to said one or more geometrical features. By these means it becomes easy for users that are not experts in robot programming to program and use the robot. The geometrical features can according to the invention be stored in storage means and used subsequently also in other settings than the specific setting in which the programming took place.

Abstract: A robot system and method for conditionally stopping a robot, wherein a maximum stopping time and/or distance are defined by a user or integrator through a user interface as safety limits based on the risk assessment. The method provides the continuous calculation of the time and/or distance, which the robot would need to stop under maximum motor torque and/or brake appliance. The robot is stopped or the speed of the robot is reduced, if the calculated time and/or distance exceeds the maximum limit values set by the user or integrator. The method may also be used to program or generate the trajectories of the robot as not to exceed the speed of the movement under the condition of keeping the set maximum stopping time and/or distance as defined by a use.

Abstract: 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.
