ABSTRACT:
A robotic vacuum cleaner is disclosed in the present invention, which comprises a controller, at least a driving wheel module, and a dust-collecting module. The controller is disposed on a housing plate. The driving wheel module, electrically connecting to the controller, further includes: a driver; a wheel connecting to the output shaft of the driver; a linkage rod, having two ends pivotally fixed on the housing plate and the driver respectively; and a resilience element, having two ends pivotally connected to the housing plate and the driver respectively. The dust-collecting module, disposed on the housing plate, is capable of vacuuming for filtering and collecting dust.
