Abstract: To improve the prevalence of screening for gastric cancer in low-income areas, a low-cost endoscope based on a novel wire-driven rotary valve and water-jet mechanism is proposed. The primary component of this endoscope is ...

Abstract: This paper presents a novel design of soft arm with triplet spiral balloons weaving and a shape memory polymer (SMP) backbone mechanism, which enables dexterous actuation and an additional variable stiffness function. The ...

Abstract: This paper presents a novel miniature contact-aided compliant mechanism (CCM) that includes flexure hinges and contact-aided structures. This continuum mechanism comprises a nickel–titanium alloy (Nitinol) tube with CCM ...

Abstract: Some special tasks require human operations and cannot be performed by robots or other autonomous equipment, such as special industrial assembly and surgical procedures in small and crowded spaces. Workers/surgeons in these ...

Abstract: AbstractParticle shape plays a crucial role in influencing the mechanical behavior of granular materials, yet its evolution under loading requires further understanding. This study validates the combined fabric evolution ...
