3-Axis Self-Leveling Robotic Arm Design & Dynamic Simulation in MATLAB Simulink Simscape Multibody
Explore a complete 3-degree-of-freedom (3-DOF) self-leveling robotic arm developed using MATLAB, Simulink, and Simscape Multibody.
This project demonstrates the design and dynamic simulation of a robotic arm capable of maintaining a level platform while undergoing dynamic motion and carrying a load.
The system combines PID-based torque control, electronic parallelogram compensation, multibody dynamics, and physical contact interaction between the carried object and platform, providing a realistic engineering simulation suitable for robotics, mechatronics, and control-system studies.
