Twisted string actuators (TSAs) have emerged as promising actuators in robotics owing to their compliant, lightweight nature, and high transmission ratios. However, practical utilization of TSAs remains limited due to their restricted stroke length and intrinsically nonlinear transmission ratio (TR)
In robotics, twisted string actuators (TSAs) have attracted considerable attention owing to their high gear ratio, flexibility, and simplicity. However, TSAs face challenges such as control issues, limited lifespan, and limited stroke. Among them, their practical use is hindered by a limited stroke
This letter presents an active-type twisted string actuator (TSA)-based continuously variable transmission (CVT). The proposed mechanism improves the advantage of the intrinsic CVT nature of TSA by compensating its nonlinear transmission ratio (TR) with the active and continuous conversion of the TR
Soft growing robots that extend through tip eversion have attracted considerable interest owing to their unique locomotion. Although the availability of visual feedback from the tip of such robots would greatly enhance their usefulness in field explorations, given that the material at the tip contin
A flexible blade that is easy to fabricate and repair is presented: It has a low impact load when colliding with obstacles, and can generate enough thrust for drone flight. The flexible blade has a camber structure that mimics the feature of dragonflies to increase wing stiffness. It makes the blade
This study presents principle of the camber-flat wing structure conversion mechanism, which is inspired by a dragonfly, and its applicability to MAV. The camber-flat wing structure convert mechanism makes MAV flight using asymmetric flapping pattern through control of angle of attack without complic…
