Abstract
An autonomous sweeper is provided, including a sweeper module, and a robot chassis having a length along a pair of sides, a front side, a back side and a top side that define an interior space. The sweeper module is configured to fit within the interior space when the robot chassis moves over the sweeper module. A pair of wheels is disposed proximate to the back side of the robot chassis and a single wheel is disposed proximate to the front side. A pair of scissor lifts is disposed along said pair of sides. A lift frame including alignment pegs that fit into corresponding alignment holes is disposed on the top side of the sweeper module. The lift frame is raised and lowered by said pair of scissor lifts, and said scissor lifts assist in lifting the sweeper module while aligning said sweeper module to the robot chassis using said alignment pegs and alignment holes.
