Torque‐Transmitting Architected Metamaterials for Flexible and Extendable Tubular Robotics

Advanced Intelligent Systems, EarlyView.
Soft and continuum robots commonly rely on fluid, tendon, or rod‐based power transmissions, to control robotic form and actuation. This study presents an architected structure, based on patterned straight‐line mechanisms, that enables simultaneous bending, extending, and torsionally rigid (BETR) transmission.

A New Design of Magnetic Gear Axial using a Rectangular NdFeB Magnetic Layer

IOP Conference Series: Materials Science and Engineering, 2019
Characteristics of magnetic-gear axial using 4 rectangular NdFeB magnetic layers mounted on acrylic disks have been studied experimentally. The goal is to reduce the use of NdFeB magnets to be more economical compared to other magnetic gear designs. The magnetic gear axial topology made was different from the magnetic gear that had been made by the ...
