Abstract: A robotic system includes a mobile base assembly and a lifting assembly. The lifting assembly includes wedge blocks, each of which is pivotably connected to a front edge of the mobile base assembly and pivotable along a hinge axis. During an operation of the robotic system, at least a portion of the wedge blocks may be slid under the boxes to lift the boxes.

Abstract: A robotic system configured for performing a task of loading and unloading goods. The robotic system comprises a mobile base assembly, an actuation assembly coupled to the mobile base assembly and configured to move with respect to the base assembly, and a head assembly mounted atop the actuation assembly or the mobile base assembly. The head assembly comprises one or more sensors configured to collect data related to an operation environment and the task to be performed. The robotic system further comprises a dynamic conveyor coupled to the mobile base assembly. The dynamic conveyor comprises a platform. The robotic system furthermore comprises a control unit configured to move the platform to align the platform with respect to the goods to be loaded or unloaded. Further, the robotic system comprises a manipulation arm coupled to the actuation assembly or the dynamic conveyor and configured to move to perform the task.
