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.
