Miniaturized Magnetic Tip Design for Endoluminal Vine Robot Navigation

Advanced Robotics Research, EarlyView.
A magnetic tip mount is designed for a miniaturized 7 mm soft‐growing vine robot to enable wireless magnetic steering and onboard imaging, while preserving a 3 mm working channel. The internal–external ring magnets design balances magnetic attachment with low eversion pressure. Experiments demonstrate ±90° steering, 34 mm bending radius, and successful

Force variability during dexterous manipulation in individuals with mild to moderate Parkinson’s disease

Frontiers in Aging Neuroscience, 2015
Parkinson’s disease (PD) is a progressive neurodegenerative disease affecting about 1-2% of the population over the age of 65. Individuals with PD experience gradual deterioration of dexterous manipulation for activities of daily living, however, current

Reinnervation of Muscle Targets Enhances the Separability of Motor Unit Signals Following Peripheral Nerve Transfers

Advanced Science, EarlyView.
Injured or cut peripheral nerves can be surgically rerouted to reinnervate new muscle targets. This study demonstrates reinnervated muscles exhibit enhanced separability between individual motor unit signals, which can simplify signal recording and decomposition. These findings highlight the potential of reinnervated muscle to serve as a key biological

Biomimetic Self‐Reconfigurable Soft Gripper for Cross‐Scale, Multi‐Particle, and High‐Load Multifunctional Manipulation

Advanced Science, EarlyView.
A fully soft, self‐reconfigurable gripper inspired by rapeseed flowers is monolithically 3D‐printed and electronics‐free, switching between diagonal and parallel finger arrangements. Establishing a self‐reconfigurable grasping paradigm, the gripper enables diverse manipulation tasks, including rotating bulbs, picking fruits, grasping cross‐scale ...
