Title: Industrial workpiece handling robot - uses corrective programming to ensure that robot handling head and workpieces arrive together
Inventor: SPONGH ROLF TORE
IPC: G05B19/418
Filed: 1977-03-23
Abstract: Some general principles are used for controlling the movement of automated industrial workpiece handling robotic machines to ensure that the arrival of a workpiece and a robot handling head coincide correctly when required on the production line. A robotic machine (1) typically has a telescopic, movable arm (2) carrying some tool which is required to operate on workpieces (4, 5) as they move along a path (3) in a production line. The behaviour of the robot and its arm (2) are determined by a programme and the arm position must coincide with that of a workpiece at the beginning of each operation. This is ensured by a set of position transducers (6), which determine the workpiece positions and feed to the programme control a series of correction signals which affect the robot (1) in the required manner.

Title: Magnetic drive system for mechanical loads - is designed to use electrical repulsion pulses in place of springs to keep drive in motion
Inventor: HARMS GEB NEUGEBAUER JOSEFINE
IPC: H02K53/00
