The invention discloses a multifunctional wheel-
leg type stair sweeping
robot which solves the problems that an existing
robot is short of intelligence, instable in climbing, insufficient in climbing ability, low in sweeping efficiency and the like in a stair region with a complex environment. The
robot comprises a
machine body, a front walking wheel, a rear walking wheel, a sweeping module and a
control system. The sweeping module comprises a power device, a rotary
brush arranged on the front portion, a middle rolling
brush arranged in the middle, a
dust collector and a trash bin, wherein the
dust collector and the trash bin are arranged behind the rolling
brush, and the
dust collector is communicated with the trash bin. The robot is also provided with a horizontal movement mechanism and a lifting mechanism, wherein the lifting mechanism is mounted on the
machine body, the horizontal movement mechanism is mounted on the lifting mechanism, and a sweeping mechanism is mounted on the horizontal movement mechanism. The wheel-
leg type stair sweeping robot is reasonable in structure, stable in climbing, high in climbing power, good in operating performance, high in sweeping efficiency, simple and practical.
