Increasing industrialization coupled with lack of awareness of safety parameters is contributing to rising amputation levels. The search for safer, simpler, and automated prosthetic arms is growing day by day. Continuous efforts are being made to design and develop prosthetic arms. But the price range has always been an issue. On the other hand, with the increasing amount of Industrialization, the necessity of robotic hand is also increasing. Also, if we look at the military technology, then using combat drones for reconnaissance and attacking over the opponent has given an extra advantage in the field of military warfare. With keeping in mind, the following scenarios this project has been developed as the primary prototype of a prosthetic arm. This hand can perform various tasks including moving and lifting the objects. However, servo motors are used to control the robotic hand. These motors' movement can be performed at any angle when needed. These servo motors are attached with Arduino while the robotic hand has been connected with jumper wire through breadboard with Arduino board. To manage the hand's function, we used two approaches: one is a flex sensor and another one is muscle signals extracted from finger movement. The robotic hand can be used for a variety of activities, including bomb dispersal, humanitarian assistance, and surgery.
