2+ day, 2+ hour ago   (165+ words) This study proposes an efficient trajectory planning method for fixed-wing unmanned aerial vehicles (UAVs) based on an improved A*-guided initialization strategy for complex obstacle environments. An improved three-dimensional A* method is developed to generate smooth and collision-free global paths…...

3+ day, 21+ hour ago   (339+ words) Post-disaster underground mine rescue requires environmental perception and remote operation before personnel can enter hazardous areas. In this article, we describe the system-level integration of a tracked detection robot, a 1432–1442 MHz wireless Mesh link, three deployable relay beacons, a handheld…...

4+ day, 18+ hour ago   (302+ words) Planning collision-free paths for unmanned aerial vehicles in cluttered three-dimensional environments requires balancing path length, smoothness, and consistency across repeated queries. However, existing bidirectional RRT* planners generally do not exploit two sources of information generated during the search: the length…...

1+ week, 2+ day ago   (383+ words) Embodied intelligence offers a system-level paradigm for improving the adaptability of robotic harvesting in complex horticultural environments by coupling perception, decision-making, and physical interaction. This review systematically analyzes recent advances in embodied intelligence for robotic harvesting. A search of the…...

1+ week, 4+ day ago   (389+ words) As a result of population ageing, rehabilitation assistive products for older adults increasingly need to meet long-term user requirements in terms of usability, comfort, and interactive experience. Although existing hand rehabilitation robots (HRRs) are capable of supporting hand training tasks,…...

1+ week, 6+ day ago   (298+ words) This paper presents a proof-of-concept study of a translational self-deployable flexible truss with distributed spherical guide-slots. A constrained trajectory-design procedure is developed by integrating guide-slot parameterization with flexible multibody dynamics. A two-stage optimization strategy is implemented, where the stowed compactness…...

2+ week, 1+ day ago   (632+ words) Unmanned aerial vehicle (UAV) remote sensing object detection remains challenging because aerial targets are often small, densely distributed, and embedded in complex background clutter, whereas onboard deployment requires compact computation and real-time inference. Existing real-time detectors commonly retain a conventional…...

2+ week, 3+ day ago   (478+ words) Hand rehabilitation orthoses play an important role in restoring upper-limb function in individuals with impaired grasp ability; however, selecting an actuation mechanism that balances functional performance, manufacturing complexity, and production cost remains a significant engineering challenge. This study aimed to…...
