Performance of Magnetic-Superconductor Non-Contact Harmonic Drive for Cryogenic Space Applications [PDF]
, 2015 Harmonic drives are profusely used in aerospace mainly because of their compactness and large reduction ratio. However, their use in cryogenic environments is still a challenge. Lubrication and fatigue are non-trivial issues under these conditions.

Subterranean Mine Inspection Using the Prometheus Re‐Configurable Drone
Journal of Field Robotics, Volume 43, Issue 3, Page 1646-1660, May 2026.ABSTRACT This paper describes the design, development, and real‐world testing of an autonomous drone for subterranean exploration, known as “Prometheus.” Driven by requirements from industry that the drone be able to be deployed through areas of restricted access, Prometheus was designed to be directly deployed through a 150 mm aperture.

Advanced Functional Materials, Volume 36, Issue 31, 16 April 2026.MAGTWIST: A compact magnetic rotary actuator, enabling smooth, stepless rotation, and on‐demand locking. Inspired by peristalsis, a soft polymer belt generates a traveling‐wave, enabling 270° rotation when heated. Cooling stiffens the belt, locking it in position and enabling it to withstand high loads.

Towards Miniaturization of Magnetic Gears: Torque Performance Assessment
Micromachines, 2017 Magnetomechanical components can be a good solution in order to reduce, or even completely avoid, friction phenomena in micro-electro-mechanical systems (MEMS) since they can transmit forces through magnetic fields without contacts. In this communication,
