The camera 410 may capture the one or more images. The camera 410 may transfer the one or more images to the controller 250. The controller 250 may transmit the one or more images arriving from the camera 410 to the remote control via the wireless connection using the wireless signals 510. In some embodiments, the camera 410 and the controller 250 may transmit at least 12 frames per second to the remote control and the remote control may display the one or more images from the camera 410 as motion video.
In some embodiments, the remote control may be a handheld R/C transceiver 460 that is dedicated to remote control of the invention 100. The handheld R/C transceiver 460 may comprise one or more joysticks 465 for controlling at least the speed and directions of the invention 100.
In some embodiments, the remote control may be a smart device 950 running an application program 470. As a non-limiting example, the smart device 950 may be a smartphone. In these embodiments, the transceiver 255 within the invention 100 may be a cell phone circuit. Specifically, the transceiver 255 may operate on the same frequencies, at the some power levels, and using the same protocols as cell phones. It may therefore be possible to establish the wireless connection between the smart device 950 and the transceiver 255 via a cell phone network. The smart device 950 may be located in a different building, city, state, or country from the invention 100 and may still operate the invention 100.
The application program 470 may provide on-screen controls to direct movements of the invention 100, may present the one or more images arriving from the controller 250, and may communicate with the transceiver 255 in the invention 100. The application program 470 may be adapted to send the wireless signals 510 to the transceiver 255 in the invention 100 to carry out the operation that was selected at the smart device 950. Responsive to the wireless signals 510 arriving from the invention 100, the application program 470 may update the display of the smart device 950 so that the one or more images arriving from the invention 100 and shown.
In use, the invention 100 may be turned on using the switch 295 and then placed on the floor. The remote control may be used to cause the invention 100 to move and to steer. The invention 100 may be driven to an area within sight of the pet and may be driven throughout an area so that the pet may give chase. If the user is not in the same room as the invention 100, the user may see where to steer the invention 100 by viewing the one or more images presented to the user on the remote control.
