A variety of expected operations, construction and performance combine the respective advantages of human and robotic machines.
Manipulator is the earliest industrial robot, but also the earliest emergence of modern robots, it can replace the heavy labor to achieve the mechanization and automation of production, can operate in a harmful environment to protect personal safety, which is widely used in machinery manufacturing, metallurgy, electronics, light industry and atomic energy and other departments.
In today's life, with the development of science and technology, the biggest difference between robot arm and human arm lies in flexibility and endurance. That is, the biggest advantage of the manipulator can repeat the same action under normal mechanical circumstances will never feel tired! The application of mechanical arm will be more and more widely, the manipulator is a kind of high-tech automatic production equipment developed in recent decades, the accuracy of the operation and the ability to complete the operation in the environment. An important branch of industrial robot manipulator.
According to the driving mode can be divided into hydraulic, pneumatic, electric, mechanical. It is characterized by a variety of expected jobs that can be programmed, with the advantages of both human and robotic machines in terms of construction and performance.
The manipulator is mainly composed of three parts: the actuator, the drive mechanism and the control system. Hand is used to grasp the workpiece (or tool) parts, according to the shape of the object to be grasped, size, weight, material and operation requirements and a variety of structural forms, such as clamping, holding and adsorption type. Motion mechanism, so that the hand to complete a variety of rotation (swing), movement or compound movement to achieve the prescribed action, change the position and posture of the object being grasped. The independent movement mode of the movement mechanism, such as lifting, stretching and rotation, is called the degree of freedom of the manipulator. In order to grasp an object at any position and orientation in space, six degrees of freedom are required. The degree of freedom is the key parameter of manipulator design. The more degrees of freedom, the greater the flexibility of the manipulator, the wider the versatility, and the more complex its structure. General special manipulator has 2~3 degrees of freedom. The control system is through the manipulator of each degree of freedom of the motor control, to complete a specific action. At the same time receive sensor feedback information, the formation of a stable closed-loop control. The core of the control system is usually composed of a microcontroller or dsp and other micro-control chip, through its programming to achieve the desired function.
