Summary: An adaptive force guidance system for laparoscopic surgery training uses self-adjusting fuzzy sliding mode controllers and switching mode controllers to provide appropriate force feedback. The system incorporates human factors and mimics the guidance of a human instructor by using virtual fixtures. Implemented and evaluated on the computer-assisted surgical trainer, the system's effects are presented based on experimental test results.

Summary: The paper proposes a virtual-force-based guidance law for path following and obstacle avoidance in unmanned aerial vehicles. The guidance law utilizes virtual spring force, virtual drag force, virtual centripetal force, and virtual repulsive force for stability and simplicity. The use of artificial physics provides a solid physical foundation and computational simplicity for the guidance law.

Summary: Helicopter collisions with obstacles are a common and severe cause of accidents. In this study, a haptic ticker cue was designed for an active sidestick to prevent these collisions during low-speed operations. Pilot campaigns and simulations were conducted to evaluate the performance of the ticker in different scenarios. The results showed that the ticker effectively warned the pilots about the hazard area they were in and significantly reduced the collision rate.

Summary: The human-machine interfaces in modern CNC machine tools are not very intuitive, still relying on outdated input systems. The proposed novel system in the paper utilizes control levers with strain-gauge sensors for manual programming, allowing intuitive control of the machine and eliminating errors in direction and speed selection. The experimental validation of the system shows its potential functionality compared to traditional CNC control methods.

Summary: This study proposes a haptic device for virtual reality applications that effectively delivers the feeling of using a tool in the virtual environment. The device focuses on hand sensations and provides realistic experiences of swinging, stabbing, and poking objects. The experiments conducted show increased realism, immersion, and enjoyment compared to using a bundle controller alone. Users also interact more actively and exaggeratedly with the haptic device. The findings suggest that previous VR experience times have little impact on satisfaction related to haptic device use, and users have low expectations for haptic realism.

Summary: A new guidance algorithm based on dynamic low-resolution image sequences is proposed to reduce the burden of obtaining high-precision lunar surface information during lunar soft landing. The algorithm utilizes a integrated procedure of dynamic descent stage and an acceptance domain algorithm to optimize the final landing site and reduce the burden on the onboard computer. Numerical simulation results confirm the validity, reliability, and effectiveness of the proposed algorithm.

Summary: The aim of this research is to develop a haptic interface that retains surgeons' prior clinical operating experience to assist robot-assisted endovascular catheterization. The haptic interface can capture surgeons' actions of catheters and guidewires and generate force and torque for surgery. Experimental results demonstrate that the proposed haptic interface has good performance and can utilize surgeons' accumulated clinical operating experience effectively.
