Abstract
The term robot comes from the Czech word robota, which when translated means "forced labor". Generally, all the robots in the world are designed for monotonous tasks. The robots handle the jobs that are difficult, dangerous or boring for a human to perform. In the medical world robots have now taken over many tasks; from a basic robotic helping hand to complex mimetic robotic arm based surgery and these chores have shown promising results. Our robotic arm is based on an innovative idea which provides help to the less mobile or paralyzed patients. Our robotic arm: Monitor Aided Radio-controlled Mobile Robot (MARCMR) is based on a robotic arm mounted over a moveable shaft, which can move from one place to another place by radio control. It uses simple gripping and dropping process to move the object which will assist paralyzed patients. MARCMR may also be helpful to work as laboratory equipment handing tool. MARCMR is controlled by using RF remote. The robot is also attached with a camera which enhances the real time view of the user. The MARCMR can be fixed by the side of a patient so that they can be able to perform their daily routine tasks and secondly they can be installed at various locations within an area where humans do not prefer to go or it might be hazardous. Keeping in mind the durability and flexibility, the MARCMR is built by using Aluminum, Plastic (PVC) and Iron. It has a wrist, elbow and shoulder joints to provide maximum closeness with a human arm. The joints are controlled with DC motors. The MARCMR revealed encouraging outcome as the patients will be able to perform their tasks with ease and they may also be allocated to the places where humans don't wish to go.
