Fig. 7 Manipulation capability experiments.
Variety of objects were manipulated by the gripper and the bottle twisting task was also performed to test its control method's performance. The GNN-based method outperformed the threshold-based method in maintaining grip force during bottle cap-twisting tasks. The GNN-based approach leads to reduced task durations, reduced contact force, and increased success rate.

The experiment was conducted by manipulating various objects. Ultimately, a real-world scenario, twisting a bottle cap, was employed to assess the level of hand manipulation.Â
