Abstract: A power-saving robot system includes at least one peripheral device and a mobile robot. The peripheral device includes a controller having an active mode and a hibernation mode, and a wireless communication component capable of activation in the hibernation mode. A controller of the robot has an activating routine that communicates with and temporarily activates the peripheral device, via wireless communication, from the hibernation mode. In another aspect, a robot system includes a network data bridge and a mobile robot. The network data bridge includes a broadband network interface, a wireless command interface, and a data bridge component. The data bridge component extracts serial commands received via the broadband network interface from an internet protocol, applies a command protocol thereto, and broadcasts the serial commands via the wireless interface. The mobile robot includes a wireless command communication component that receives the serial commands transmitted from the network data bridge.

Abstract: A self-propelled electronic device comprising; a housing; a drive wheel that enables the housing to travel; a wheel drop sensor that detects loss of contact of the drive wheel with a floor surface; and a travel control unit that controls travel of the housing, wherein, when the wheel drop sensor detects loss of contact of the drive wheel with the floor surface, the travel control unit continues travel of the housing for a predetermined continuous travel time, and if the wheel drop sensor still detects loss of contact of the drive wheel with the floor surface after the continuous travel time has elapsed, the travel control unit stops the rotation of the drive wheel, and then, rotates the drive wheel in a direction opposite to the direction of the rotation for a predetermined reverse travel time, to cause the housing to travel in a reverse direction.

Abstract: A housing contains a plurality of motorized transport units in a stacked relationship to one another, with a bottom-most one of the plurality of motorized transport units serving as a locomotion mechanism that selectively causes movement of the housing with the plurality of motorized transport units contained therein. By one approach the aforementioned housing has a cylindrical form factor and includes a cylindrically-shaped chamber configured to receive the motorized transport units, By one approach, for example, this housing includes no lifting mechanism to lift any of the motorized transport units into itself and further has no integral locomotion mechanism by which the housing can move itself. The interior of the housing can include at least one track formed therein to receive a corresponding part of each of the plurality of motorized transport units which the motorized transport units can engage to thereby lift themselves into the interior of the housing.

Abstract: A guide-type virtual wall system is provided. The system comprises a beacon (11, 44) and a robot (12), wherein a transmission module of the beacon (11, 44) directionally transmits a first signal, and an area covered by the first signal defines a beacon signal area (13). The robot (12) comprises a beacon signal receiving module corresponding to the beacon signal transmission module. When the robot (12) enters the beacon signal area (13) and the beacon signal receiving module detects the first signal, the robot (12) advances towards the direction of the beacon (11, 44) until it detects a second signal, and then the robot (12) crosses over or exits from the beacon signal area (13). The system can restrict the robot (12) from entering a certain area, wherein the area where a virtual wall is located is not missed, and the robot (12) is also enabled to cross over the virtual wall to enter the restricted area when required.

Abstract: A robot cleaner includes a main body traveling along a floor surface and removing foreign substances in a cleaning travel mode, a sensor unit sensing obstacles around the main body, brush units sweeping foreign substances on a floor surface through rotation, and a controller reducing the traveling velocity of the main body and causing the main body to approach a front obstacle, if an area where a plurality of obstacles contacts each other is sensed by the sensor unit.
