Transport carriage with two hexapod platforms with increased range of movement
A carriage with two hexapod platforms, each having a base, a plate, and a set of six cylinders associated in pairs. Each cylinder is articulatedly mounted with the plate. For each pair, a slider is able to move in translation on the base. For a first pair, the two cylinders of the first pair are mounted in an articulated manner on the slider. The articulation of one of the two cylinders of the first pair with the plate is adjacent to the articulation of one of the two cylinders of a second pair with the plate. The articulation of the other of the two cylinders of the first pair with the plate is adjacent to the articulation of one of the two cylinders of a third pair with the plate. For each slider, a movement system moves the slider. A control unit controls each cylinder and the movement system.

There is provided a parallel link device including a base, a plurality of arms each having at least four degrees of freedom and each including a first arm link, a second arm link, and a rotating joint, and a support which is coupled to an end of the second arm link of each of the plurality of the arms, and a position and a posture of which changes along with changes of posture of the plurality of the arms, where an axis of rotation (O7) of the rotating joint, which is coupled to the support and the second arm link, intersects or is adjacent to a rotational central point (Q) of the support.
METHOD AND CONTROL SYSTEM FOR THE CALIBRATION OF A HANDLING APPARATUS
The invention relates to a method to calibrate a handling device (18) including a handling robot or parallel kinematic robot (24), with a tool head (28) suspended from at least two parallel kinematically movable arms (26). Each of the at least two arms comprises an upper arm, which is movable between two end positions about a defined upper-arm swivel axis (38). Each of the at least two arms also comprises a lower arm (40), which is swivelably mounted on the upper arm. The upper arms are brought into approximately corresponding angular positions by detection of load torques and/or of angle positions. First one, than another of the upper arms is brought into one of the two end positions, and the angular position reached is detected and used for the position initialization or angle initialization of the particular upper arm, whereupon the upper arm is returned.
