A robot system includes: a robot comprising a joint driven by a motor; and a circuitry configured to: execute position control of the motor based on position commands; store torque commands generated based on the position commands during execution of the position control of the motor; and execute torque control of the motor based on the stored torque commands.

A control device for operating a machine tool having a motor-driven, traversable and positionable tool head. The control device executes a freely programmable control program and determines or co-determines the sequence of operations of the machine tool. The control device also comprises a user interface for influencing the sequence of operations of the machine tool by manual control, at least one operating element for manually controlling changes to movements of the tool head being formed on the user interface. A multi-functionally designed operating element is designed to manually preset or influence a feed rate during a machining phase of the tool head and which multi-functionally designed operating element, in a second usage mode, is designed to manually preset or influence a rapid-traverse rate during a rapid-traverse phase of the tool head. The multi-functionally designed operating element is designed as a rotary actuator operating element comprising a continuously rotatable actuating member.

A method for estimating a wrench acting on a reference point of a robot includes the steps of: a) measuring at least one component, but not all components, of the wrench; and b) estimating non-measured components of the wrench based on a dynamical model of the robot while taking into account the measured components.
