Twisted nylon actuators (TNAs) are widely recognized in soft robotics for their excellent load-to-weight ratio and cost-effectiveness. However, limitations deformation output force restrict ability to support more advanced applications. Here, we report 3 performance-enhancing strategies inspired by the construction process of chromosome, which validated through novel types TNAs. First, design a dual-level helical structure, demonstrating remarkable improvements (60.2% vertically...
Twisted and coiled actuators (TCAs) are a type of thermal-driven actuator with high energy density display the enormous application potential to drive soft robots. However, existing robots driven by TCAs scarce can only realize grabbing creeping movement almost without load capacity. The main reason is that TCA fabricated traditional self-coiling method has low force long thermal response time. Aiming improve output TCA, fabrication enhancement principle multitwisted (MTCAs) developed....
Small soft pumps are extensively explored in medical fields and robotics, but the insufficient flow rate constrains their applications. In this article, an intersected twisted artificial muscle unit (ITAMU) is proposed to achieve a large contraction ratio, which adapted drive developed pump, characteristics of high no noise pollution achieved. The configuration principle ITAMU pump depicted. Besides, ratio calculated theoretically. Then, prototypes manufactured tested. results indicate that...
In the field of surgery, minimally invasive surgical robots (MISRs) have emerged as persistent pursuit physicians to minimize harm and perform precise surgery. The structure newly proposed MISRs tends change from rigid flexible, which poses a challenge control. this article, an MISR actuated by self-helix twisted artificial muscles (SHTAMs) with large bending angle high precision is developed. configuration operation principle are illustrated. Then, physical model SHTAM kinematics end...
Soft robots made from soft materials show great advantages over rigid in environmental adaptability and motion flexibility. However, too body makes them lose the load capacity, which limits their applications locomotion. Although crawling tensegrity with both bars flexible cables are potential to address this challenge, existing inchworm friction drive methods difficult realize of a single unit. Besides, lack appropriate actuators robot configuration also blocks development robots. This...
A basic understanding of the affinity between hydroxyapatite (HA) and α-Ti surfaces is obtained through electronic structure calculations by first-principles method. The surface energies HA(0001), HA (011̅0), (101̅1), Ti(0001) have been calculated. HA(0001) presents most thermodynamically stable HA. HA/Ti interfaces were constructed two kinds interface models, single (denoted as SI) double-interface DI). Two methods, full relaxation UBER, applied to determine interfacial separation atomic...
Soft actuator is the key component for soft robots to realize flexible motion. But difficulty of sensing and control actuators seriously restricts their application. Twisted artificial muscles (TAMs) made from together self-coiling nylon 6,6 fiber heating wire are potential address this challenge due extremely high actuating stress self-sensing ability. However, coiled twisted (TCTAMs) have a large hysteresis because small area process deformation stroke. Besides, lack accurate physical...
A basic understanding of the influences substituted silver and zinc on adhesion between hydroxyapatite (HA) α-Ti surfaces is obtained through first-principles electronic structure calculations. Since (0001) plane presents most thermodynamically stable surface HA, HA/Ti interfaces with Zn or Ag dopants were constructed HA(0001) Ti(0001) surfaces. Applying universal binding energy relation (UBER), optimal interfacial distance for interface models are estimated then optimized determined after...
Soft robots made from soft materials can safely interact with humans and environments compared the traditional rigid robots. However, inherent compliance of makes them difficult to realize jumping motion. Although many jump through design bistable structure. existing need spine be embedded in body. Therefore, it is still hard for a robot pure This paper offers method ability. The critical buckling force total elastic potential energy increased by designing body different thickness. We use...
