Problems solved by technology

[0004] The domestic patent application No. 201110026500.9 discloses a rope-driven parallel robot that can realize rapid reconfiguration. The device is composed of multiple sets of drive modules, reversing devices and output devices. However, since there is no real-time measurement of tension, the control accuracy is relatively low. Low cost, complex structure, difficult installation and maintenance, and higher cost

Embodiment Construction

[0081] In this embodiment, a multi-configuration rope-driven parallel robot includes: a moving platform 1000, several rope-driven devices 2000, a main frame 3000 and several ropes 4000;

[0082] According to the needs of the task, the rope drive device 2000 is arranged at any position of the main body frame 3000; figure 1 As shown, the moving platform 1000 is located in the internal space of the main frame 3000, and the position and posture can be changed arbitrarily in the internal space; the rope driving device 2000 is connected with the moving platform 1000 through the flexible rope 4000, and uses the space pose to solve The method obtains the pose of the moving platform 1000 in the internal space of the main body frame 3000, thereby using the flexible rope 4000 to pull the moving platform 1000 to a corresponding position in the main body frame 3000, and changing the The corresponding posture of the moving platform 1000 is described. The connection mode between the flexibl...

Abstract

The invention discloses a multi-configuration rope drive parallel robot and a space position and posture solution method thereof. The multi-configuration rope drive parallel robot is characterized by comprising a movable platform, a plurality of rope drive devices, a main rack and a plurality of ropes, wherein the rope drive devices can be arranged in an arbitrary position of the main rack according to task requirements; the movable platform is in an inner space of the main rack, and positions and postures of the movable platform can be freely changed in the inner space; the flexible ropes connected with the rope drive devices are arranged on the movable platform; and the rope drive devices pull the movable platform through the self ropes to move in arbitrary positions of the space in the main rack. According to the multi-configuration rope drive parallel robot, position and posture control precision of the rope drive parallel robot and utilization efficiency of robot devices can be improved.

Description

technical field [0001] The invention relates to the field of a cable-driven parallel robot, in particular to a multi-configuration cable-driven parallel robot and a method for calculating its space and posture. Background technique [0002] Parallel robots have the advantages of large working space, strong load capacity, fast reconfigurability, and modular design. The advantages of rope drive make the target working platform have a larger working range and faster movement speed, and are being widely used in various operating mechanisms. In the above, the position and attitude of the braking platform in the work space is controlled by controlling the output length of the rope; in the driving process, not only the output length of the rope needs to be precisely controlled, but also the tension on the rope needs to be detected; the drive of the existing rope-driven parallel mechanism Most of the devices cannot be integrated with measuring devices. The traditional measuring meth...
