R3Arm: Gesture controlled robotic arm for remote rescue operation

In this paper, a low-cost gesture-controlled robotic arm system, namely R3Arm (Remote Rescue Robotic arm) is developed for the remote rescue operation. It offers remote manipulation with ease of portability. The robot can be deployed to places where no humans can go and has the ability to become part of massive rescue operations. It also offers live video feed of its operation and can save human life stuck in difficult situations if built with the proper structure which certifies the advantage of its modular body. The robot's arms are equipped with claws and possess three degrees of freedom which helps to grab and move a wide variety of things. Extensive testing has been carried out with the developed robot and a satisfactory performance is obtained in terms of gesture response, communication range and dynamic video feedback at different conditions.
