Multidirectional Motion Strategy of Miniature Water Surface Robot Actuated by Single Exciter
Advanced Robotics Research, EarlyView.A novel multidirectional motion strategy on the water surface based on a single exciter is proposed, and a single‐exciter single‐plate module is developed for actuation. The driving forces generation mechanism of the module is revealed from the perspective of the asymmetric surface wave field.
