摘要： A planetary wheel type obstacle crossing robot, including a frame, a front drive set, and a rear drive set, is provided. The front drive set and the rear drive set are respectively connected to a front end and a rear end of the frame. The front drive set includes a dual-drive steering wheel structure, which includes two drive wheels and two first drive devices. The first drive devices respectively output different rotational speeds to the drive wheels, so that the dual-drive steering wheel structure rotates. The rear drive set includes two planetary wheel sets, two second drive devices, and a planetary wheel set suspension structure. Each planetary wheel set is individually driven and includes a front wheel, a rear wheel, and an upper wheel. The wheels of each planetary wheel set cooperate to climb over an obstacle under an action of a driving torque output by the second drive device.

摘要： A multi-level structure conveying system and method for assisting UAV landing are provided. The system includes conveying units and modular bottom plates. The modular bottom plate provides line connection between a power supply and a controller for the conveying unit. The conveying unit drives a UAV to move through driving a conveyor to move. Placement of the conveying units in different directions is used to control a movement direction of the UAV. The conveying units are connected through side plate modules to be arranged into conveying modules with different trajectories. The UAV moves on the conveying modules under driving of each conveying unit to reach a target position. A side plate bump of each conveying unit is sleeved opposite to a side plate recess of the adjacent conveying unit. A hollow channel formed by side plate holes of the adjacent conveying units is fixed by adopting a connecting shaft.
