Robotic Arm

A robotic arm is a long, thin structure similar to a human arm. It can be programmed to perform different functions. It is widely used for gripping, spinning, welding , and assembling different objects. Robotic arms can be automatic or remote-control operated. They can also be mobile or stationary.

Applications Robotic arms are highly accurate and can perform repetitive tasks over and over. They are widely used in indus- tries and space-based applications. While automatic robotic arms are mostly used in industries, remote-con- trol operated arms are used in space. Human beings use these robotic arms to manipulate heavy payloads in space and to maintain space ships.

Structure A robotic arm is made up of similar parts as a robot. It consists of a con- troller, driver, sensors, and a movable structure. Different types of joints can be used to make a robotic arm depend- ing on the task it has to perform. It is quite easy to build a robotic arm as compared to a humanoid robot. This is because a robotic arm works in a small, fixed area and has a fixed function.
