Robot Arm

The robot arms are usually used in plastic molding industry and automatic production line to stead of human hand.

Robotic arm is a type of mechanical arm, usually programmable, with similar functions to a human arm.

The arm may be the sum total of the mechanism or may be part of a more complex robot.

The links of such a manipulator are connected by joints allowing either rotational motion (such as in an articulated robot) or translational (linear) displacement.

The links of the manipulator can be considered to form a kinematic chain.

The terminus of the kinematic chain of the manipulator is called the end effector and it is analogous to the human hand.
