A key issue in the research of intelligent prosthetics is the verification and analysis of the proposed prosthetic motion planning and control methods. In this paper, it is proposed that using a humanoid walking robot as the subject can effectively test the interaction dynamics between the prosthesis and the human body. This method also avoids the risk of injury to amputee patients when participating in the test before the control method is mature. Specifically, the anthropomorphic walking of bipedal walking robots is first realized, and a testbed that fully simulates the straight leg walking is obtained. The right leg (below the thigh) of the bipedal robot is then replaced with an intelligent prosthesis. When testing the planning and control methods of intelligent prosthetics, prosthetic controllers run independently. The bipedal walking robot, except for the part below the right thigh, normally performs the "humanoid motioncontroller". Effective intelligent prosthetic control methods will make the prosthesis-"human" coupling system produce smooth walking movements, while ineffective intelligent prosthetic control will cause the coupling system to fall due to strong interference.

Teleoperation has become increasingly crucial for military, civil, and space applications. This study examines how dynamic environments, such as the remote control of a robot from a vehicle in movement, affect teleoperation performance. We evaluate the effects of changing gravitational cues provided by a motion platform, on operators' teleoperation of a drone in virtual reality, and explore different visual interfaces to enhance performance. Preliminary findings suggest that teleoperation from dynamic environments can lead to reduced performance, with 3rd person perspective (3PP) potentially mitigating negative effects. While further research is needed, our results initiate the exploration of the relationship between body movement and teleoperation for more efficient and safer practices.

This paper explores Particle Swarm Optimization (PSO) based control of a morphing robot arm mounted on a controlled Floating Space robot (CFSR). CFSR is a new study spacecraft model allowing controlled adjustments of the satellite base's pose. The dynamic model of the chaser spacecraft is derived relative to the target in an inertial frame, using the Clohessy-Wiltshire model or Hills equations for defining their relative motion. It is assumed that both spacecraft are in an Inplane-elliptical formation. The manipulator dynamics are obtained through Lagrangian formulation. The PSO algorithm optimizes controller gain values while a quintic polynomial trajectory is provided as input to the arm joints. Results show that the PSO-based controller effectively reduces tracking error and power requirements, and it is also compared with a conventional proportional-derivative (PD) controller.
During the motion of a robotic arm, its response speed and trajectory accuracy are crucial. This paper analyzes the control mode of the traditional PID controller, combines the principle of particle swarm algorithm, a...
