In complex systems like aircraft engines and oil refinery machines, pipeline inspection is an essential task for ensuring safety. Here, we proposed a type of smart material-driven robot (weight, 2.2 grams; length, 47 millimeters; diameter, <10 millimeters) that could fit into pipes with sub-centimeter diameters different curvatures. We adopted high-power density, long-life dielectric elastomer actuators as artificial muscles composite microstructure-based, high-efficiency anchoring units...
The motion of rotation is ubiquitous in daily life and industry. Compared with electromagnet motors, smart‐material‐based rotary motors may exhibit more flexibility, robustness, adaptability. Herein, a lightweight, compact dielectric elastomer actuator (DEA) motor remarkable performance reported. driven by multilayered, slightly‐prestretched (<10%) (DE) composite membrane which consists low‐loss silicone as the DE layers single‐walled carbon nanotube electrodes. When operating at...
Dielectric elastomers, used as driver modules, require high power density to enable fast movement and efficient work of soft robots. Polyacrylate elastomers usually suffer from low under electric fields due limited response frequency. Here, we propose a bimodal network polyacrylate dielectric elastomer which breaks the intrinsic coupling relationship between mechanical properties, featuring relatively constant, Young's modulus, wide driving frequency bandwidth (~200 Hz) like silicones....
Abstract Soft pneumatic robotics are designed for safe and compliant interaction with the environment or humans. However, systems used actuation protection still relatively bulky rely on rigid components such as solenoid valves pressure regulators. This study presents design analysis of soft fibrous (SFVs) internal tiny channels external helical structures, which could be in systems. Made from material, SFVs demonstrate unique capabilities controlling by partial expansion under specific...
Human-robot collaboration (HRC) in a shared workspace has become common pattern real-world robot applications and garnered significant research interest. However, most existing studies for human-in-the-loop (HITL) with robots evaluate either simplified game environments or physical platforms, falling short limited realistic significance scalability. To support future studies, we build an embodied framework named HumanTHOR, which enables humans to act the simulation environment through VR...
