Outline of Final Research Achievements |
In this study, we conducted technological expansions to enable autonomous movement based on a previously developed inchworm-type multi-degree-of-freedom small self-propelled machine that utilizes the expansion and contraction of piezoelectric elements and the attraction of electromagnets. We clarified the following components: the collaboration between a global camera installed externally and a local camera mounted on the small self-propelled machine, the acquisition of electrical signals to estimate levitation using vertical vibrations and the measurement of the correlation of the levitation amount, methods for transmitting information detected by the small self-propelled machine to the external environment, and the configuration of wireless power supply and the power conversion circuit mounted on the movement mechanism to achieve this. These advancements enabled the movement of the self-propelled machine.
