specific Embodiment approach

[0073] In addition to being able to complete the grasping work, the modular multi-joint wire-controlled robot also needs to have the ability to move flexibly in a large space. In order to realize the above functions, as a specific implementation of the modular multi-joint wire-controlled robot provided by the present invention , the workbench 50 includes the following parts (see figure 1 , figure 2 , Figure 8 and Figure 9 ):

[0074] a first mobile platform 51;

[0075] The first screw mechanism 56 is connected with the first mobile platform 51 to drive the first mobile platform 51 to move;

[0076] The first driving mechanism 58 is connected with the first lead screw mechanism 56;

[0077] The first fixed seat 54 is connected with the first mobile platform 51 and is used to support the first screw mechanism 56 and the first drive mechanism 58; the first screw mechanism 56 is located inside the first fixed seat 54, and the first drive mechanism 58 is located at the si...

Abstract

The invention provides a modular multi-joint drive-by-wire robot comprising a workbench, a plurality of joints connected in series, a jaw and a power mechanism; the bottom joint is arranged on the workbench, each joint comprises a shell and a connecting mechanism, and the two adjacent joints are connected via a rotating shaft fixedly connected with one of the joints; each rotating shaft is provided with a pull wheel; the power mechanism comprises a box body, a plurality of electric pull rods and pull wires connected to the electric pull rods one by one; each pull wheel is connected with one pull wire, and the jaw is connected with one pull wire. According to the modular multi-joint drive-by-wire robot, each rotating shaft can drive one of the joints to rotate and can be closely connected to another joint, and structures between the joints are compact; the pullback length of the pull wires can be accurately controlled by the electric pull rods, the rotating shafts are driven by the pullwheels, the pull wires and the electric pull rods to rotate, so that the joints driven by the rotating shafts can rotate accurately; each joint is controlled by the independent pull wire to rotate independently so as to have good motion precision.

Description

technical field [0001] The invention belongs to the technical field of robots, and more specifically relates to a modular multi-joint wire-controlled robot. Background technique [0002] The modular robot is composed of standard independent manufacturing modules, and each module has a driving part, a power source, etc. Different modules are combined and controlled by the control system to form a robot with special functions. [0003] Typical representatives of modular robots are snake-like soft robots and parallel robots. Snake-shaped soft robots can imitate snakes in nature through the rotational motion of cross joints, such as snakes in nature, linear motion, lateral motion, and telescopic motion, but their control methods are relatively complicated and the joint structure is also relatively complicated, resulting in high cost. Because of its powerful functions, compact structure, high rigidity, large carrying capacity, no cumulative error, and high precision, parallel r...
