Abstract: A method for controlling a robot in at least one pose of the robot wherein the robot can be operated in either a first mode of operation or a second mode of operation. In the second mode of operation the robot can be moved by manually applying a guiding force to the robot. The method includes determining a distance of a state variable of the robot from a first limit and then triggering a safety response when the distance satisfies a first condition and the robot is operating in the first mode of operation. When the robot is operating in the second mode of operation and the distance satisfies the first condition, the method includes not triggering the safety response, and motorically applying a positioning force to the robot in dependence on the determined distance so that the distance can be reduced when the robot is unobstructed.

Abstract: A method for moving along a predetermined path with a robot in an at least a partially automated manner includes determining a deployment position on a current path section of the predetermined path for which a distance parameter satisfies a predetermined condition, and moving to the deployment position with the robot. In one aspect, the robot may be moved to the deployment position if a deployment condition is satisfied. The distance parameter may be determined on the basis of a distance of a current position of the robot relative to the current path section. The predetermined condition may be that the distance parameter has a value that is less than or equal to the values of the distance parameter of all positions in a partial area of the current path section, which is in particular complementary to the deployment position.
