Innovative Design and Implementation of a Cost-Efficient 5-Axis Adaptive Robotic Arm for High Precision Tasks

The design, building, and use of a 5-Axis Adaptive Robotic Arm with sensor-based feedback control for exact and effective item manipulation are shown in this work.    Combining high-torque servo motors, an Arduino Mega microprocessor, and an adaptive force-sensing gripper, the gadget is supposed to be a versatile and financially inexpensive replacement for conventional multi-degree-of- freedom robotic arms.    Operating two different modes, manual control—in which operators utilise potentiometers for precision positioning—and automated execution—in which recorded movement sequences for repetitive tasks—the robotic arm.    Unlike traditional 6-DOF robotic arms, this system maintains functional dexterity while removing a redundant joint, hence reducing complexity and expense.   In industrial automation, educational applications, and assistive robots, real-time grip modifications based on object sensitivity made feasible by a pressure sensor dramatically increase arm’s efficiency.   Experimental analyses demonstrate that the performance of the system is defined by smooth motion transitions, accurate positioning, adaptive grip control, and energy-efficient operation.   This work highlights the possibilities to design low-cost robotic arms with adaptability and accuracy able to manage different automation tasks.
