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.

Robot comprising safety system ensuring stopping time and distance

A safety system for an industrial robot, specifically an industrial robot and a method for implementing a safety system via predefined safety functions. To perform such safety functions the robot comprises in a joint connecting two robot arm sections a first position sensor () for sensing the angular orientation on an input side of a gear in the joint, and a second position sensor () for sensing an angular orientation on an output side of the gear.
