Abstract:
PROBLEM TO BE SOLVED: To provide a device for relative movement of two elements that is simply constructed, is able to arrange two elements adjacently, and has necessary rigidity and strength. SOLUTION: The device for relative movement of two elements 1, 2 comprises two link arrangements 5, 6 coupled in series by a connection arrangement 4. The first link arrangement 5 comprises at least three links 9, 14 which are substantially equal in length and parallel, the links being positioned in a substantially triangular relation viewed along the longitudinal direction of the links, between the connection arrangement 4 and the element 2. The second link arrangement 6 comprises at least one parallelogram acting between the connection arrangement 4 and the element 1. First and second force applying arrangements 17, 18 are adapted to cause the first link arrangement 5 to pivot. A third force applying arrangement 33 is adapted to cause the second link arrangement 6 to pivot. COPYRIGHT: (C)2008,JPO&INPIT

The present invention relates to an industrial robot comprising: a platform (16) arranged for carrying the object, a first arm (7) arranged for influencing the platform in a first movement and comprising a first actuator having a first path (1) and a first carriage (4) linearly movable along the first path, a second arm (8) arranged for influencing the platform in a second movement, comprising a second actuator having a second path (2) and a second carriage (5) linearly movable along the first path, a third arm arranged for influencing the platform in a third movement, and a control unit controlling the movements of the platform. The first and second arm are arranged rotatable in such way that the platform is movable between opposite sides of a second plane (D) passing through and continuously following the first and second carriage The control unit comprises control means adapted to upon command perform a reconfiguration of the platform and the arms of the robot, wherein the reconfiguration comprises moving the platform between opposite sides of the second plane.
Abstract:
The invention relates to a joint comprising a male unit (12) and a female unit (15, 16). The external surface of the male unit (12) is of complementary shape to the internal surface of the female unit (15, 16). The units cooperate and have shapes allowing rotational movement in at least one degree of freedom of the male unit within the female unit. The female unit (15, 16) comprises two socket parts (15, 16). According to the invention biasing means (21 ) is provided for biasing each of the socket parts (15, 16) towards the male unit (12).
Abstract:
The invention relates to a system for controlling the position and orientation of an object (1,3). The system comprises a measuring assembly (6) including a first (7) and a second part (8), wherei n the first part is adapted to receive forces and torques from a user, and a sensor (9) adapted to measure forces and torques caused by changes in position and orientation of the first part in relation to the second part, and a data processing unit (18) arranged to receive measured data from said sensor and based thereon to control the position and orientation of the object. The sensor comprises a semiconductor chip with integrated sensor elements. The measuring assembly comprises a spring arrangement (11) mounted between the first and second parts and mechanically connected to the sensor, for converting forces and torques from the user to changes in position and orientation of said first part in relation to said second part, and said sensor is adapted to measure forces and torques from the spring arrangement caused by the changes in position and orientation of the first part.
