Abstract: A wireless communication system comprises a first computing device and a second computing device, wherein the first computing device and the second computing device communicate over a wireless channel that is selected based in part on a geographic location of at least one of the first computing device and the second computing device. The wireless channel that is selected provides long range communications, on the order of 60 miles and more. The computing devices may be a robot controller and a controlled robot, or they may be wireless router and a computing device configured with a wireless transceiver.

Abstract: Devices communicate with one another over a wireless channel according to a signal strength of a signal transmitted over the wireless channel. Digital data captured at a source is transmitted over the wireless channel at a first quality if the signal strength or latency is above a threshold and at a second quality if the signal strength or latency is below the threshold. In addition, noise can be inserted into the transmitted digital data as a way to alert the recipient of the signal of signal strength degradation at a finer granularity.

Abstract: A doll controlling device controls a doll driving device to make a doll carry out movement for selling foods or drinks. A releasing device releases one of foods or drinks from a food or drink harvesting device when the releasing device is supplied with a money receipt signal and a selecting signal. A sound producing device produces sounds which are useful for selling foods or drinks. The dispenser for foods or drinks selling device may further comprise a cooking device for cooking foods or drinks from the harvesting device.
