To provide a technique for accurately taking off and landing at the takeoff and landing port of an aircraft. The takeoff and landing system according to the present invention includes an aircraft having a takeoff and landing unit 5 with a takeoff and landing area and having a predetermined outer diameter in a side surface view, and a takeoff and landing port 10 wherein, when the takeoff and landing area of the takeoff and landing unit 5 of the aircraft 1 is included in and makes contact with the takeoff and landing surface of the takeoff and landing port 10, a predetermined outer diameter in a side surface view is larger than the length at the outer edge of the takeoff and landing surface.

A system and method for a recharging station including an elevated landing pad, a rechargeable component coupled to the elevated landing pad, a power delivery unit configured to deliver power from a power supply unit or power storage unit to the recharging component, and a support component coupled to the bottom of the elevated landing pad.

Disclosed are a collaborative charging method, apparatus, and logistics device, which relate to the technical field of logistics. One specific implementation mode of the method comprises: judging whether remaining battery power of a first logistics device satisfies a preset charging condition; if so, determining a target second logistics device for charging the first logistics device; and controlling the target second logistics device to move to meet the first logistics device so as to charge the first logistics device. According to the implementation mode, collaborative charging between respective logistics devices can avoid problems such as low charging efficiency and energy waste caused by necessity of returning to a charging station for charging.

This specification describes an electrically powered modular platform comprising a power module comprising a common power bus, the power module electrically connected to a power source; one or more service modules that provide a service; a termination module that is configured to cover an opening in the one or more service modules, wherein the power module, each of the one or more service modules, and the termination module are modular and stackable, and wherein the power module and each of the one or more service modules are electrically connected using the common power bus to provide power to each of the one or more service modules.

The present disclosure relates to an in-place alignment method for wireless charging of an urban air mobility and a device and a system therefor. A wireless charging method in an urban air mobility includes diagnosing a state of at least one sensor included in the urban air mobility, requesting the supply device to drive a sensor included in the supply device through wireless communication based on a result of the diagnosing, measuring a location of the supply device by sensing a sensor signal of the supply device, moving the urban air mobility to the supply device based on the measured location of the supply device, and stopping the urban air mobility, performing alignment of wireless power transmission/reception pads for wireless charging, and performing wireless charging based on completion of the alignment. Therefore, the present disclosure has an advantage of maximizing a wireless charging efficiency and minimizing a power waste by quickly and accurately aligning wireless power transmitting/receiving pads of the urban air mobility and the supply device with each other in place.

An example UAV landing structure includes a landing platform for a UAV, a cavity within the landing platform, and a track that runs along the landing platform and at least a part of the cavity. The UAV may include a winch system that includes a tether that may be coupled to a payload. Furthermore, the cavity may be aligned over a predetermined target location. The cavity may be sized to allow the winch system to pass a tethered payload through the cavity. The track may guide the UAV to a docked position over the cavity as the UAV moves along the landing platform. When the UAV is in the docked position, a payload may be loaded to or unloaded from the UAV through the cavity.

An antenna for charging and measurement may comprise: a telescopic support installed at a lower portion of an aerial vehicle and configured to contract when the aerial vehicle lands on a wireless station and extend when the aerial vehicle takes off from the wireless station; and an antenna coil part deformed into a spiral shape when the telescopic support is contracted so that the wireless station receives wireless power and deformed into a conical shape when the telescopic support is extended to measure a radio signal.
