Short summary
Short summary
This paper proposes a parallelogram-based adaptive grasping device to overcome the limitations of conventional rigid grippers. It integrates adaptive parallelogram units and a 2-RRR planar parallel driving mechanism. Screw theory and kinematic analysis validate its performance, while a bevel gear set minimizes driving motors. Grasping tests confirm its favorable dimensional adaptability, providing theoretical and engineering references for adaptive grasping equipment design.

Short summary
Short summary
A planar prismatic Rubik's cube mechanism is defined as a Rubik's-cube-inspired mechanism where components only carry out planar motion. Based on a physical prototype, this paper illustrates the composition, topological configuration, and reconfigurable motion process of the mechanism. The type synthesis method proposed in this paper not only creates more novel mechanism configurations but also enriches and improves the type synthesis theories for planar mechanisms.

Short summary
This paper proposes a novel 4-degree-of-freedom parallel mechanism. Its degrees of freedom are verified by screw theory. Inverse position, velocity, and acceleration models are established. The position workspace is obtained, and singular configurations are identified. The stiffness index distribution in the workspace is visualized. The inverse dynamic model is derived using the Lagrangian method. Kinematic and dynamic simulations in Adams verify the correctness of the theoretical model.
