A technique of camera exposure control for vision-based navigation of an unmanned aerial vehicle (UAV) includes acquiring an aerial image of a ground area below the UAV with an onboard camera system of the UAV, estimating a visual motion factor based on a speed of the UAV and an altitude of the UAV, and adjusting an exposure control setting of the onboard camera system based on the visual motion factor.

Disclosed is a boxing training system with a feedback function, including a training robot, a boxing glove assembly and a virtual reality device. The training robot performs a displacement movement. The boxing glove assembly is located on a user's hand and hits the training robot. The virtual reality device is electrically connected to the training robot and the boxing glove assembly, respectively. The virtual reality device is located at the user's eyes and displays a virtual image. The virtual image has a virtual opponent and a virtual boxing glove. When the virtual boxing glove hits the virtual opponent, the boxing glove assembly just hits the training robot.

A method is disclosed. The method includes receiving an indication of presence of an aircraft in a vicinity of an uncrewed aerial vehicle (UAV) which is flying along a flight path. The method also includes decelerating, based on the received indication, the UAV to reduce a ground speed along the flight path. The method additionally includes descending, after reducing the ground speed, the UAV to a hover position. The method further includes determining, while the UAV is in the hover position, whether to resume the flight path or to land the UAV based on a determination of continued presence of the aircraft in the vicinity of the UAV. The method also includes controlling the UAV based on the determination of whether to resume the flight path or to land the UAV.
