Problems solved by technology

[0002] At present, the space manipulators used in orbit mainly adopt the single-arm design method, and the number of degrees of freedom generally does not exceed 7. It has relatively fixed operating capabilities, and is limited by the ground launch capability. The length of the arm is generally shorter than that of the cabin. , the number of degrees of freedom is relatively small, resulting in a very limited working space when the base of the manipulator is fixed or when performing cargo handling operations. Some parts are too far away and cannot be reached, and some parts are unreachable due to obstacle interference constraints.

Embodiment Construction

[0031] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0032] Such as figure 1 As shown, a super-redundant drive manipulator capable of space on-orbit assembly of the present invention includes: a main manipulator 10 and an auxiliary manipulator 20;

[0033] Such as figure 2 As shown, the main mechanical arm 10 includes a first arm 131, a second arm 132, a main arm elbow joint with one degree of freedom, a main arm shoulder joint with three degrees of freedom, and a main arm with three degrees of freedom. Wrist joint, central controller 14, main arm shoulder end effector 121 and main arm wrist end effector 122;

[0034] One end of the first arm 131 is connected to one end of the second arm 132 through the main arm elbow joint 114; the other end of the first arm 131 is connected to one end of the main arm shoulder joint, and the second The other end of the arm rod 132 is connected to one end of the wrist jo...

Abstract

The invention discloses a spatial hyper-redundant drive manipulator. According to the spatial hyper-redundant drive manipulator, the manipulator extension function is realized in the form of cascade connection between a main manipulator and an auxiliary manipulator; meanwhile, the manipulator redundant operating capability is greatly improved; the realization form is relatively simple and reliable; and the operating functions and the operating performance of the original manipulator are not influenced. According to an on-orbit assembling method of the spatial hyper-redundant drive manipulator, all joints of the main manipulator and the auxiliary manipulator can be uniformly planned and controlled by a central controller of the main manipulator; such a time-sharing control manner that coarse positioning operation is performed at the first 7 degrees of freedom as well as fine positioning operation and the like are performed at the last 6 degrees of freedom can be adopted; compared with 13-degree-of-freedom redundant operation, the time-sharing control manner has the advantage that the operation control difficulty can be greatly reduced under the premise that the operation precision is guaranteed; and meanwhile, the three intermediate joints are shared, so that the space resource utilization ratio is greatly improved.

Description

technical field [0001] The invention relates to the technical field of space manipulators, in particular to a space super-redundant drive manipulator and an assembly method. Background technique [0002] At present, the space manipulators used in orbit mainly adopt the single-arm design method, and the number of degrees of freedom generally does not exceed 7. It has relatively fixed operating capabilities, and is limited by the ground launch capability. The length of the arm is generally shorter than that of the cabin. , the number of degrees of freedom is relatively small, resulting in a very limited working space when the base of the manipulator is fixed or when performing cargo handling operations. Some parts are too far away and cannot be reached, and some parts are unreachable due to obstacle interference constraints. . Contents of the invention [0003] In view of this, in order to overcome the shortcomings of existing space manipulators in terms of length and redun...
