Abstract: 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.

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.

Abstract: Provided are servers and methods for authenticating software files. A server includes a processor circuit and a memory coupled to the processor circuit. The memory includes computer program instructions that, when executed by the processor circuit, cause the authentication server to perform operations including verifying, using a public key, signature data corresponding to a single certificate file for authenticating a software installation package file that was signed using a private source key. Operations may include, responsive to verifying that the signature data matches an originally signed single certificate file, reading an image file segment table from the software installation package file. The image file segment table includes multiple records that correspond to ones of multiple image file segments of the software installation package file.
