Thumb Controlled Low-Cost Prosthetic Robotic Arm

Not everyone is gifted with perfect limbs. There are people in this world who lose their precious body parts in accidents or diseases. They are also not up to speed with the staggering development of technology and productivity. To solve this issue, the area of prosthetic limbs has been widely explored since its inception. However, the existing solutions are financially out of the reach for general people of developing countries. In this paper, a low-cost robotic arm has been proposed which is affordable to above or below elbow amputees. Using servo motors, Arduino UNO, end effector etc. to construct the proposed system can enable a person to move, grasp and replace objects that are heavy or require both hands to carry. A prototype of the model has been made to show the efficiency, productivity and cost analysis of the proposed system. The result displays that the system is cost-effective and affordable to the poverty-stricken section of the community.
