Dumpsite Seabed Characterization of the San Pedro Basin, CA, From Autonomous Vehicle Observations

Journal of Field Robotics, EarlyView.
ABSTRACT A wide‐area seabed survey was conducted using autonomous underwater vehicles (AUVs) in a known dumpsite off the coast of Southern California that has been found to have widespread sediment contamination from the chemical dichlorodiphenyltrichloroethane (DDT).

Biomimetic robots driven by smart materials: Motion forms, stimulation methods and applications

Responsive Materials, EarlyView.
Biomimetic robots enhance adaptability by mimicking biological systems, but rigid materials limit performance. Smart materials with stimuli responsiveness and shape adaptability enable more flexible actuation and improved environmental interaction.

A Compact Annular Electrostatic Clutch Joint: Dynamic Response Modeling and Time‐Sharing Control for Underactuated Robots

SmartBot, EarlyView.
Electrostatic clutches offer programmable variable stiffness for multi‐DOF robots, but their continuous motion is usually bottlenecked by spatial constraints and detachment delays. Here, the authors report a compact annular electrostatic clutch joint with a biphasic amplitude‐frequency modulation strategy to rapidly mitigate residual polarization ...

FEWT: Frequency‐Enhanced Wavelet‐Based Transformer for Multimodal Wheeled Bimanual Manipulation

SmartBot, EarlyView.
An embodied mobile bimanual robot learns dexterous manipulation skills through imitation learning with multimodal perception. The integration of vision, proprioception, and tactile sensing establishes a comprehensive perception–action loop, enabling the robot to continuously understand, interact with, and adapt to complex physical environments.

An Ergonomic Customizable Soft Robotic Glove Toward Personalized Hand Rehabilitation

SmartBot, EarlyView.
Soft robotic gloves for hand rehabilitation are often limited by poor fit and uneven pressure on the fingers. Here, the authors report an ergonomic all‐fabric glove whose dual‐action actuators are tailored to individual finger geometry by CNC heat sealing, with symmetrical chambers that distribute interface pressure more evenly. Weighing only 90 g, the

Improving Human Diving Endurance With a Field‐Deployable Exoskeleton

SmartBot, EarlyView.
High energetic demands to overcome drag, combined with a finite supply of self‐contained breathing gas, fundamentally limit human endurance in underwater locomotion. Here, we present DiveMate, a portable exoskeleton that provides adaptive bidirectional assistance synchronized with fin‐kicking during diving, reducing lower‐limb muscle activation and ...

Foot and Ankle Exoskeleton [PDF]

This paper presents a non-motorized foot and ankle exoskeleton to assist persons who have no lower limb or abdominal function. Exoskeletons are defined as “an artificial external supporting structure” [1], they are wearable devices that can be used to ...
