Modeling and Analysis of Micro-Spacecraft Attitude Sensing with Gyrowheel
Sensors, 2016 This paper proposes two kinds of approaches of angular rate sensing for micro-spacecraft with a gyrowheel (GW), which can combine attitude sensing with attitude control into one single device to achieve a compact micro-spacecraft design.

Giant Diffusion of Nanomechanical Rotors in a Tilted Washboard Potential
Physical Review Letters, 2022 We present an experimental realization of a biased optical periodic potential in the low friction limit. The noise-induced bistability between locked (torsional) and running (spinning) states in the rotational motion of a nanodumbbell is driven by an elliptically polarized light beam tilting the angular potential. By varying the gas pressure around the

Four-Dimensional Gait Surfaces for a Tilt-Rotor—Two Color Map Theorem
Drones, 2022 This article presents the four-dimensional surfaces that guide the gait plan for a tilt-rotor. The previous gaits analyzed in the tilt-rotor research are inspired by animals; no theoretical base backs the robustness of these gaits.
