摘要:
The invention relates to a positioning device with a supporting structure, with a work carrier (22) and with length-adjustable struts (70, 72; 186), which are respectively connected on one side to the supporting structure and on the other side to the work carrier (22), wherein the struts (70, 72; 186) are movably mounted at the points of connection to the supporting structure and the work carrier (22), wherein at least some of the struts (70, 72; 186) are adjustable in length and wherein at least some of the struts (70, 72; 186) have a drive for adjusting their length. At least six of the struts (70, 72; 186) are arranged in pairs. In the case of one pair of struts (58, 60, 62; 126), the struts (70, 72; 186) are arranged in parallel and each pair of struts (58, 60, 62; 126) has a pivot bearing (24, 26, 30, 32; 78, 80; 84) at a first end of the longitudinal extent of the struts (70, 72; 186). Finally, each pair of struts (58, 60, 62; 126) also has a second bearing at a second end of the longitudinal extent of each strut (70, 72).

The invention relates to a method and to a system for aligning and controlling the position of a robot tool, wherein a monitoring device (600) is equipped with a detection unit (610) and processing unit (620) which co-operates with the control device (630) of the robot and automatically determines the alignment of the robot tool (205) by means of the detection unit (610) by taking into account at least one pre-determined reference direction of the robot tool (205), in addition to at least one predetermined tolerance angle which defines a tolerance range for the at least one reference direction of the robot tool (205). The processing unit (620) compares the determined alignment to the predetermined reference direction and/or to the tolerance values predetermined by the defined tolerance range and/or if the at least one tolerance range is not respected, the respective robot tool (205) is disconnected and/or deactivated in co-operation with the control device (630) of the robot (200).

The invention is related to a robot manipulator system (10), comprising • a robot manipulator with a kinematic chain of stiff robot manipulator segments (12, 14, 16, 52, 54, 56, 81, 82), which are linked together by hinged joints (18, 20, 58, 60, 84), • a robot controller (22) for controlling the execution of a robot program, • at least one temperature sensor (24, 26, 28, 90, 92, 94, 126) for providing measured temperature values, whereas at least one heatable cover (30, 32, 34, 66, 70, 86, 88, 120, 130) is attached onto at least one manipulator segment (12, 14, 16, 52, 54, 56, 81, 82) for applying heat energy thereon, whereas the belonging amount of heat energy is controlled by a control unit dependent on measured temperature values (38) of the at least one temperature sensor (24, 26, 28, 90, 92, 94, 126).
摘要:
The invention proposes a method for heating of robots in cold environments, whereby the robot possesses permanent magnet brushless or three-phase synchronous motors (1) with three motor phases comprising three stator coils (L 1 , L 2 , L 3 ) connected to an inverter (3) controllable by a control-unit (4) and with a rotor with permanent magnet excitation (2). A current is applied to at least one phase respectively stator coil (L 1 , L 2 , L 3 ) of the motor (1) if the motor stands still creating a directed magnetic flux (Φ) which interacts with the permanent magnets of the rotor in such a way that the resulting torque will be close to zero. Further the invention proposes a system for heating of robots in cold environments whereby the inverters (3) and motors (1) in standstill are used to heat up the critical drive train components, where by at least one supervisory-control-unit (5) monitors the motor temperature in order to avoid overheating.
