The movement mechanism enables the hand to complete various rotations (swings), movements, or composite movements to achieve prescribed actions and change the position and posture of the object being held. The independent movement modes of the movement mechanism such as lifting, telescoping, and rotation are called the degrees of freedom of the Dongguan manipulator.
In order to capture objects at any position and orientation in space, 6 degrees of freedom are required. The degree of freedom is a key parameter in robot design. The more degrees of freedom, the greater the flexibility of the Dongguan manipulator, the wider the versatility, and the more complex its structure.
General dedicated Dongguan manipulators have 2 to 3 degrees of freedom.
The control system performs specific actions by controlling the motor of each degree of freedom of the Dongguan manipulator. At the same time, the sensor feedback information is received to form a stable closed-loop control. The core of the control system is usually composed of a single-chip microcomputer or a micro-control chip such as dsp.
