Embodiment Construction

[0010] Such as figure 1 As shown, the present invention mainly comprises: fixed platform 1, branched chain AA 0 , branched chain BB 0 , branched chain CC 0 1. The moving platform 5 is connected in the following manner: the fixed platform 1 is fixed horizontally and is the support of the whole mechanism, and its shape is isosceles △A 0 B 0 C 0 , where A 0 is the vertex, B 0 C 0 is the bottom edge, at the three corners of the fixed platform 1 and the branch chain AA respectively 0 , branched chain BB 0 , branched chain CC 0 It constitutes the connection of moving pairs, the three moving pairs are all in the vertical direction, the three driving motor seats are placed on the fixed platform 1, and the branch chain AA 0 , branched chain BB 0 They are respectively connected with the moving platform by ball joints, and the branch chain CC 0 The connection with the moving platform is a point contact. The shape of the moving platform 1 is isosceles △ABC, where A is the ape...

Abstract

A movable six-freedom mixed robot is composed of a static platform, three branch joins AAo, BBo and CCo, and a movable platform. Said branch join AAo (or BBo) has three guide rods: moving rods X, Y and Z, whose moving directions are mutually perpendicular for realizing the movement in X, Y and Z directions. The moving rods X, Y and Z of AAo and the moving rods Y and Z of BBo have drive force but the moving rod X of BBo has not. It can realize 6-freedom movement of movable platform. Its advantages are good decoupling performance of branch joins, high rigidity of movable platform, and no error accumulation.

Description

technical field [0001] The invention relates to a mobile robot, in particular to a mobile six-degree-of-freedom hybrid robot capable of realizing six-degree-of-freedom motion of a moving platform. Background technique [0002] When the parallel robot controls the movement of the platform, it has the following advantages compared with the serial robot: (1) large rigidity, stable structure, and strong bearing capacity; (2) no error accumulation and high precision; (3) the motor is placed on a fixed platform, and the movement Small load, good dynamic performance; (4) Position reverse solution is easy to solve, suitable for online real-time control. However, compared with the series robot, the parallel robot has a smaller space for movement, and the movement of the movable platform is not as flexible as the hand of the series robot, and the position is difficult to solve. The advantages and disadvantages of the parallel structure and the series structure are exactly the opposit...
