Origami sheds light on the design of mechanisms and robots. In this paper, inspired by an origami structure, an enveloping grasping mechanism is proposed. The origami-inspired grasping mechanism (OIGM) is symmetrically designed and has only one degree-of-freedom (DOF), which can be utilized to develop a gripper that can fully enclose the objects. The kinematic characteristics of the mechanism are analyzed. In particular, we integrate a leaf-spring-based bistable mechanism with the OIGM to design a gripper with a passive bistable grasping capability. Triggered by the impact force between the gripper and the object, the gripper can passively grasp objects. To validate the passive grasping capability of the gripper, a prototype is fabricated and the grasping experiment is conducted.

Electrostatic adhesion is emerging as a promising mechanism for wall-climbing robots to achieve both adhesion and detachment. Although numerous studies have investigated the gait and structure of these robots, the adhesion mechanism remains controlled by an external voltage source, which increases the weight and wiring burden. Additionally, high adhesion typically requires high voltage. To address these issues, this paper proposes a dynamic electrostatic adhesion model for the first time. The adhesive force is entirely generated by the contact-separation movement between the adhesive footpads and the substrate. We developed a theoretical model to elucidate the generation of electrostatic adhesion. By combining multiple parameters into dimensionless variables, we identified optimal conditions using only two parameters to predict optimal adhesion, thereby guiding the parameter design of dynamic electrostatic adhesion. Furthermore, we found that the electrical energy dissipated by resistance is equal to the negative work done by adhesion in one cycle, offering a theoretical basis for measuring the adhesion force.

The traditional motion vice and rigid structure of the human upper limb complex joints between the forms of movement present significant challenges to ensuring consistency and addressing other problems. This paper proposes a 6-degrees-of-freedom cable-driven upper limb rehabilitation flexible parallel robot. The robot combines a flexible parallel mechanism with the advantages of light mass, good flexibility, and the ability to realize complex force position control. First, this paper examines the anatomy of human upper limb skeletal muscles. Second, a three-dimensional motion capture system is employed to obtain experimental data and to analyze the range of motion of the human upper limb. Finally, the structural design of the shoulder joint, elbow joint, and wrist joint is completed.

A multi-robot collaboration can reliably perform complex tasks that would be difficult for a single robot to accomplish, especially advanced welding operations in complex components with heterogeneous materials. We focused on a three-dimensional (3D) trajectory planning for complex components with heterogeneous materials, and carries out the research of multi-robot collaboration. By using the software of robot simulator CoppeliaSim, the comparative simulation analysis of multi-robot active-slave and distributed in 3D intersecting line was proposed. Through the establishment of multi-robot collaborative experiment system, the trajectory planning of multi-robot axial motion with semi-8 was put forward. Simulation and experimental results show that our proposed multi-robot system is feasible and is capable of realizing 3D trajectory planning for complex components with heterogeneous materials.
