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.
