Abstract

The invention relates to a controllable mechanism type two-degrees-of-freedom mobile manipulator. A fourth connecting rod of the manipulator is of a triangular shape; the lower end of a first driving part is connected to a mobile platform and the upper end of the first driving part is connected with one end of a first connecting rod; the other end of the first connecting rod is connected with one end of a second connecting rod; the other end of the second connecting rod is connected with an operation platform; the lower end of a big arm is connected to the mobile platform and the upper end of the big arm is connected with the first end of a fourth connecting rod and simultaneously, the upper end of the big arm is connected to the second connecting rod by a compound hinge; the lower end of the third connecting rod is connected to the mobile platform and the upper end of the third connecting rod is connected with the second end of a fourth connecting rod; one end of a fifth connecting rod is connected with the third end of the fourth connecting rod and the other end of the fifth connecting rod is connected with the operation platform; the lower end of a second driving part is connected to the mobile platform and the upper end of the second driving part is connected with one end of a sixth connecting rod; the other end of the sixth connecting rod is connected to the big arm. According to the invention, the stress condition of the manipulator is improved; the defects of rotational inertia, residual vibration intensity and the like of the manipulator are reduced; moreover, the controllable mechanism type two-degrees-of-freedom mobile manipulator has the advantages of easiness for implementing remote control, reduction of labor intensity of workers and the like.

Description

Technical field [0001] The invention relates to a device in the technical field of robots, in particular to a controllable mechanism type two-degree-of-freedom mobile mechanical arm. Background technique [0002] The robotic arm is a device used to implement actions such as grasping. Certain tools can be installed on the end operating platform of the robotic arm to perform various operations. It is widely used in national defense, space exploration, logistics, EOD, assembly, etc. In the field, the mobile robot arm expands the working space of the robot arm through the movement of the mobile platform, which makes it superior to the traditional fixed-link robot arm and has a broader application prospect. [0003] The research of domestic mobile manipulators started relatively late, but after decades of development, great progress has been made. At present, the research of domestic mobile manipulators mainly focuses on manipulator structure, motion control technology, path planning te...
