ChicGrasp: Imitation‐Learning‐Based Customized Dual‐Jaw Gripper Control for Manipulation of Delicate, Irregular Bio‐Products

Advanced Robotics Research, EarlyView.
Automated poultry processing lines still rely on humans to lift slippery, easily bruised carcasses onto a shackle conveyor. Deformability, anatomical variance, and hygiene rules make conventional suction and scripted motions unreliable. We present ChicGrasp, an end‐to‐end hardware‐software co‐designed imitation learning framework, to offer a ...

Dead Matter, Living Machines: Repurposing Crustaceans' Abdomen Exoskeleton for Bio‐Hybrid Robots

Advanced Science, EarlyView.
Crustacean exoskeletons, repurposed from food waste, are engineered into sustainable bending actuators combining biotic structure with synthetic control. The augmented exoskeletons achieve rapid and robust motion with lightweight body and can be used as part of robotic manipulators, grippers and swimmers.

MELEGROS: Monolithic Elephant‐Inspired Gripper with Optical Sensors

Advanced Science, EarlyView.
MELEGROS is a monolithic, elephant‐inspired soft gripper integrating 3D‐printed optical sensors within a pneumatically actuated lattice. Simulation‐guided design decouples tactile and proprioceptive sensing. Characterized through grasping tests, MELEGROS can reach, scoop, and grasp, showcasing a paradigm where fully embedded sensing and continuous ...

Haptic Interface for Center of Workspace Interaction [PDF]

, 2002
We build upon a new interaction style for 3D interfaces, called the center of workspace interaction. This style of interaction is defined with respect to a central fixed point in 3D space, conceptually within arm\u27s length of the user.

Mapping CSC‐Mediated Ovarian Cancer Chemoresistance via CXCR4‐PET to Guide Precision Cisplatin Re‐Sensitization Therapy

Advanced Science, EarlyView.
CXCR4 functions as a potential cancer stem cell‐associated marker linked to chemoresistance in ovarian cancer, and an inhibitor of CXCR4, AMD3100, can enhance the cytotoxic response to cisplatin. Based on these findings, [68Ga]Ga‐Pentixafor positron emission tomography enables selective visualization of CXCR4‐high ovarian cancer, while AMD3100 combined
