Leveraging open-source designs, EvoGrip enhances accessibility, adaptability, and dexterity. Its mechanical structure, derived from the Inmoov arm, was refined to incorporate position and force sensing with improved finger mechanics for precise and reliable performance. Two modeling strategies and a dual control scheme using Model Predictive Control (MPC) were proposed and experimentally validated. The system achieved accurate finger trajectories and effective disturbance rejection, demonstrating the potential of MPC for robotic hand control. Although some reactive behavior was observed in multi-finger scenarios, decentralized controllers showed promising results, indicating potential for more advanced control strategies. This work establishes a foundation for future extensions, including multi-input, multi-output MPC and reinforcement learning to enhance coordination and robustness.
