Designing of Robotic Arm Decoding Hand Gestures using Arduino Nano

摘要

The work focuses on developing a versatile robotic arm, combining digital design, hardware construction, and programming using Arduino Nano. The process begins with the comprehensive design and prototyping of the robotic arm using Autodesk Fusion 360, a parametric modeling tool. The robotic arm features and key components such as servo motors, and its construction is systematically detailed. Integration of the Arduino Nano is explored for seamless system connectivity, with a gesture-controlled circuit diagram. The programming logic, illustrated governs the robotic arm's response to input data from sensors, particularly a gyroscope and a flex sensor. The robotic arm displays movements across axes: forward (0 to 60 degrees) and reverse (300 to 360 degrees) in motions in X-Axis governed by Motor 1; leftward (0 to 60 degrees) and rightward (300 to 360 degrees) motions in Y-Axis Motion governed by Motor 4; upward (300 to 360 degrees) and downward (0 to 60 degrees) motions in Z-Axis governed by Motor 2. Gripper Control governed by Motor 3, manages gripper closure beyond a flex sensor input of 750 and maintains an open position below this threshold. These precise movements showcase the robotic arm's versatility and controlled response to specific angle ranges showcasing the system's performance, and effective control over different movements, gripper regulation, and lateral motion.
