Microfabrication of Soft Millirobots Propelled by Low Voltage Electrohydraulic Actuators

Advanced Materials Technologies, EarlyView.
Manual layer‐by‐layer assembly is replaced by wafer‐level MEMS batch fabrication for compliant polymer‐based electrohydraulic actuators. The microfabricated devices integrate sacrificially defined microcavities, Parylene‐C‐sealed inlets, and multilayer polymer–metal films.

Calibration for a Planar Cable-Driven Parallel Robot

Journal of Institute of Control, Robotics and Systems, 2015
This paper proposes a calibration algorithm for a three-degree-of-freedom (DOF) planar cable-driven parallel robot (CDPR). To evaluate the proposed algorithm, we calibrated winches and an optical tracking sensor, measured the end-effector pose using the optical tracking sensor, and calculated the accurate robot configuration using the measurement ...

Toward Perception‐Native Electronic Skin: Bio‐Inspired In‐/Near‐Sensor and Neuromorphic Computing for Humanoid Robots

Advanced Materials Technologies, EarlyView.
Dense tactile streams from across the humanoid body converge on collide in a central wiring and data bottleneck. By relocating computation closer to and then into the skin itself, near‐ and in‐sensor architectures, together with neuromorphic computing, chart a path toward perception‐native electronic skin, in which the conversion of stimulus into ...

Liquid Crystal Elastomer Actuator Matrix for Large Area Applications

Advanced Materials Technologies, EarlyView.
A scalable approach is used to manufacture a digitally‐controllable, 2D 5 × 5 actuator matrix. The elements of the matrix are produced by direct ink writing of a liquid crystal elastomer ‘artificial muscle’ on large‐area flexible thin‐film heaters. In optimizing the low‐power actuators, multiple heater designs and substrate materials are investigated ...

8-DoFs Cable Driven Parallel Robots for Bimanual Teleoperation

IEEE/ASME Transactions on Mechatronics
Teleoperation plays a critical role in intuitive robot control and imitation learning, particularly for complex tasks involving mobile manipulators with redundant degrees of freedom (DoFs). However, most existing master controllers are limited to 6-DoF spatial control and basic gripper control, making them insufficient for controlling high-DoF robots ...

Design of an Earthquake Simulator Based on a Cable Driven Parallel Robot

Robotics
Due to the fact that an earthquake cannot be predicted, the simulation of earthquakes using earthquake simulators is of great importance. An earthquake simulator is a device that reproduces the seismic waves that all generated by an earthquake. The aim of this work is present the design and prototyping earthquake simulator that simulates a real long ...

From Rigid to Soft Robotic Approaches for Neuroendoscopy

Advanced Robotics Research, EarlyView.
Robotic assistance has had minimal impact on deep intraventricular surgeries, where small‐scale, precision, and reduced invasiveness can contribute to improved patient outcomes. Emerging technologies in rigid, soft, and hybrid robotics are reviewed to identify the most promising mechanisms for deep brain navigation in addition to an attempt to identify
