Gesture-Controlled Robotic Arm

Abstract

Robotic arms are highly effective for industries that demand quick and reliable performance. These efficient devices are essentially automated systems that, unlike humans, do not get tired or need a rest. These machines have been used for many years but have recently progressed significantly with the advancement of complex sensors. Robotic arms of today come with various sensors that let them move around and react quickly in their working areas. This paper introduces a human hand gesture-controlled automatic low-cost robotic arm. In this proposed system, an Arduino Mega microcontroller gets the information from all the sensors and correctly manages the servomotor with the help of the value of sensors. All the sensors required to control the various servos on the robotic arm are placed into a hand glove. The robotic arm is operated in this system by two flex sensors. One flex sensor is linked to the glove’s forefinger section to manage the arm’s claw, and another is attached to the middle finger section of the glove to regulate the arm’s wrist. A gyroscope is also pinned to the glove to track the movement of the forearm and base. As a result, the base servo moves clockwise or counterclockwise depending on whether the hand glove is angled right or left. However, if the hand glove is angled upward or downward, the gyroscope data will cause the forearm servo to rotate either clockwise or counterclockwise. The sensors’ values are converted to the servo motors’ rotational degrees. The sensors’ values are converted to the servo motors’ rotational degrees. The claw, wrist, forearm servos and base of the proposed robotic device can rotate up to 90 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">0</sup> , 45 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">0</sup> , 120 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">0</sup> and 180 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">0</sup> degrees, respectively.
