A kind of mechanical arm and robot and robot experiment system

Abstract

The invention provides a mechanical arm, comprising a base, a controller, a driver mechanism, and an arm body mechanism, characterized in that: the base has a cavity structure, and the controller is arranged in the cavity structure; the driver mechanism and the arm body mechanism are arranged on the base and rotate relative to the base, wherein the arm body mechanism is hinged on the driver mechanism; the arm body mechanism includes a plurality of arm bodies, and the middle part of the arm body It is a hollow frame body with a fully enclosed structure, and two ends of the hollow frame body are provided with connecting parts, and the connecting part includes two side walls and is in an open structure. The mechanical arm provided by the present invention provides a base that integrates support, control, and workbench without additional fixed installation; the overall structure of the mechanical arm is compact and can be arranged in a portable manner. The invention also provides a robot and a robot experiment system, which can complete more tasks and have better teaching and demonstration effects.

Description

technical field [0001] The invention belongs to the technical field of robots, and in particular relates to a mechanical arm, a robot with the mechanical arm, and a robot experiment system. Background technique [0002] Existing mechanical arms generally have a mounting base and a control box. The installation base generally needs to be fixed by installation (usually by means of screws or bolts) in order to realize the stable operation of the supporting robot arm, including the overall rotation of the supporting robot arm; while the control box is connected to the installation base through a control line, that is, the control The box is used to control the rotational movement of the mounting base. [0003] In the prior art, the mounting base and the control box are designed in separate structures. During work, the separately provided control box is placed on one side of the installation base, thereby causing the installation of the mechanical arm to take up a large space a...

AI Technical Summary

Problems solved by technology

When working, the separate control box is placed on one side of the installation base, which causes the installation of the robot arm to take up a large space and is inconvenient to use

Especially for desktop robotic arms, the mounting plate at the bottom is usually fixed on the desktop by bolts, the installation is complicated and the portability is poor; at the same time, the external control box is not convenient for the installation and arrangement of the robotic arm

The control box also has the problem of single function and inconvenient expansion

[0004] At the same time, the control wires from the control box to the installation base are usually arranged outside the manipulator after being drawn out from the control box, and when there are multiple drive sources on the installation base and multiple control wires are required, the wires arranged outside the manipulator will appear Problems such as clutter not only affect the appearance, but also affect the movement of the robotic arm due to the winding of the control line

In the prior art, the control line is hidden inside the robotic arm. Although it can solve the aesthetic problem, it still cannot solve the technical problem of affecting the movement of the robotic arm due to the winding of the control line, especially the continuous rotation of the robotic arm relative to the base.

Therefore, wiring has always been a difficult problem plaguing the robotic arm industry
