Problems solved by technology

But as a robot manipulator, using compressed air as a power source, the strength of the robot manipulator is no longer strong enough
[0004] At present, household robots can only talk and chat with people, but cannot do housework
Service robots can serve dishes in hotels, but the cost of manipulator joints using servo motors and harmonic reducers is very high

Abstract

The invention discloses a prosthesis mechanical arm, a robot and a robot control method. Each of a shoulder joint, an elbow joint and a wrist joint is formed by a pneumatic or hydraulic steering device and a sector-shaped air bladder or hydraulic bladder. Finger joints are formed by sector-shaped air bladders or hydraulic bladders, and a pneumatic or hydraulic jack is mounted between each two adjacent finger extension bones of a palm. By electromagnetic waves sent by a biochip connected with upper limb nerves to a computer in an upper arm, the prosthesis mechanical arm controls electromagnetic valves to further control feeding and discharging of compressed air or liquid in the pneumatic or hydraulic jacks, the sector-shaped air bladders or hydraulic bladders and the pneumatic or hydraulic steering devices in the prosthesis mechanical arm, and consequently the prosthesis mechanical arm is enabled to operate. A robot arm of the robot is identical to the prosthesis mechanical arm. Joints of mechanical legs and feet and neck joints of the robot are formed by pneumatic or hydraulic steering devices and the sector-shaped air bladders or hydraulic bladders, and two pneumatic or hydraulic jacks and a sector-shaped air bladder or hydraulic bladder are hidden in a body of the robot. The robot is controlled by the aid of a computer.

Description

Technical field: [0001] The invention relates to a prosthesis mechanical arm, a robot and a control method thereof. Background technique: [0002] The length of the arm of the manipulator of existing robot is fixed, and each joint is all two-dimensional 360 ° steering, and needs two joints to do all-round steering. Therefore, the manipulator of the robot with six joints has appeared. Each joint is composed of a servo motor and a reducer. Because of its complex structure and high precision, the quality of servo motors and reducers made in my country is not high. Most servo motors and almost all reducers need to be imported. So that the cost of the manipulator of existing robot is very high. The manipulator joints of existing robots can only do two-dimensional steering; they cannot do three-dimensional steering like the human hand joints. In the narrow range of space, the flexibility of the manipulator of existing robots is not as good as that of human hands. For example: a...
