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.
Claims29
A robotic system comprising:
- a mobile base assembly configured to maneuver the robotic system about a floor surface;
- a lifting assembly at a front side of the robotic system, wherein the lifting assembly comprises a plurality of wedge blocks arranged along a lateral direction, each wedge block of the plurality of wedge blocks having a substantially planar top surface that is inclined downward, such that the wedge block has a thickness that tapers toward a thin front edge of the wedge block;
- one or more conveyer belts rearward of the lifting assembly, wherein the one or more conveyer belts are configured to receive an item lifted by one or more wedge blocks of the plurality of wedge blocks and move the item toward a rear side of the robotic system;
- and
- an actuator configured to pivot a first wedge block of the plurality of wedge blocks about a lateral axis independently of other wedge blocks of the plurality of wedge blocks.
