Mechanical ARM 

Designed a mechanical arm that mimics the action of a human arm. One end of the arm is attached to a firm base, while the other has a tool. They can be controlled by humans either directly or over a distance.

Working of the mechanical arm -

• The mechanical arm design includes a series of joints, articulations, and manipulators that work together to closely resemble the motion and functionality of a human arm (at least from a purely mechanical perspective).
