Devices and methods for activating a flight-enable beacon configured to provide a light beacon or data signal comprising capability to establish and maintain a fixed set of coordinates. The flight-enabled beacon is configured with a processor, memory, motor, gimbal or swashplate and light emitting source and can be configured to attain and maintain a target altitude and emit a light over a fixed period of time. The flight-enabled beacon is configured to be light and with small form factor for easy portable transport in cases of emergency or to provide a signal easily locatable by parties located a distance from the activated light-enabled beacon.

A service vehicle can have a service vehicle battery that can provide energy to, and/or receive energy from, a separate machine that is normally configured to operate based on energy provided by a battery of the machine. If a machine becomes unable to operate using the battery of the machine, the service vehicle can travel to the machine and use an energy transfer arm to transfer energy to the machine. In some situations, the service vehicle and the machine can travel together in a convoy formation, for instance to a maintenance station, while the service vehicle provides the machine with energy for driving operations of the machine.

Disclosed is a configuration of an autonomous vehicle for autonomously following a moving subject based on a radius of a virtual sphere surrounding the autonomous vehicle. The autonomous vehicle may be an unmanned ground vehicle or an unmanned aerial vehicle, which autonomously follows the subject (e.g., a device, a live entity, or any object) based on the virtual sphere. The radius of the virtual sphere may be dynamically configured according to a velocity of the autonomous vehicle or configurations of a camera coupled to the autonomous vehicle. Accordingly, the autonomous vehicle can follow the subject along a smooth trajectory, and capture images of abrupt movements of the subject in a cinematically pleasing manner.

A cleaning robot includes a navigator to move a main body, a remote controller to output a modulated infrared ray in accordance with a control command of a user and to form a light spot, a light receiver to receive the infrared ray from the remote controller, and a controller to control the navigator such that the main body tracks the light spot when the modulated infrared ray is received in accordance with the control command. Because the cleaning robot tracks a position indicated by the remote controller, a user may conveniently move the cleaning robot.

A space coupling system for coupling real space with virtual space is provided. A real position in the real space and a virtual position in the virtual space are associated with each other. A first real position is the real position of a real person in the real space or the real position of a screen configured to move following the real person. A first virtual position is the virtual position associated with the first real position and changing in conjunction with the first real position. The space coupling system acquires the first real position and the first virtual position, locates an access point accessible by a virtual person at the first virtual position in the virtual space, and displays or projects information regarding the virtual person or an image of the virtual space around the access point on the screen in the real space.

An unmanned aerial vehicle is described and includes a computer carried by the unmanned aerial vehicle to control flight of the unmanned aerial vehicle and at least one sensor. The unmanned aerial vehicle is caused to fly to a specific location within a facility, where the unmanned aerial vehicle enters a hover mode, where the unmanned aerial vehicle remains in a substantially fixed location hovering over the specific location within the facility and sends raw or processing results of sensor data from the sensor to a remote server system.
