Abstract
A mobile object apparatus includes an electric power reception unit that receives electric power transmitted in a non-contact manner from, out of a plurality of power feed apparatuses that are allocated to a plurality of small areas within a predetermined area and are capable of transmitting electric power in a non-contact manner, the power feed apparatus allocated to the small area adjacent to the mobile object apparatus, a drive unit that executes a movement operation on the predetermined area, and an electric power storage unit that stores an electric power amount requisite for the movement operation to the small areas within a predetermined range from the adjacent small area.
Claims10
A mobile object apparatus, comprising:
- an electric power reception circuit configured to receive electric power in a noncontact manner from a power feed apparatus of a plurality of power feed apparatuses, wherein the plurality of power feed apparatuses is allocated to a plurality of subareas within a specific area, a position of the mobile object apparatus is at a first sub-area of the plurality of sub-areas, and the power feed apparatus is allocated to the first sub-area;
- a servomotor configured to execute a movement operation to move the mobile object apparatus from the first sub-area to a second sub-area of a set of sub-areas of the plurality of sub-areas, wherein the set of sub-areas is closer to the first sub-area than remaining sub-areas of the plurality of sub-areas;
- an electric power storage circuit configured to store an electric power amount requisite for the servomotor to execute the movement operation, wherein the movement operation is executed once at most based on the stored electric power amount;
- a direct current-direct current (DC-DC) converter connected to the servomotor and the electric power storage circuit;
- and a control circuit configured to turn off the DC-DC converter, based on the stored electric power amount becoming less than a threshold value and completion of the execution of the movement operation.
