摘要： A self-propelled, dust-collecting robot includes a main-body part including a dust collection box, and a first battery pack, which has a case, at least one battery cell in the case, a control circuit board having a controller mounted in the case, and a discharge terminal. The main body part includes a first battery pack mount having a connector to which the first battery pack is removably connectable. The first battery pack is configured for use in an electric power tool.

摘要： An electric motor serving as a drive source of a dust collection mechanism 20 is arranged such that a motor axis line of the electric motor is tilted with respect to a base portion of a main body case. Because of this configuration, a main body is made to be compact in the front-to-rear direction, in comparison to a configuration where the motor axis line of the electric motor is disposed parallel to the base portion.

摘要： A self-propelled, dust-collecting robot includes a chassis, an electric motor supported by the chassis, and first and second rechargeable battery packs disposed inside the chassis for supplying current to the electric motor. First and second castors are respectively disposed immediately underneath the first and second battery packs. Each of the battery packs has a pair of rails that respectively slide into and engage with complementary guide rails coupled to the chassis. A dust-collection box is removably disposed within the chassis. A dust-collection motor rotates a suction fan that is in fluid communication with the dust-collection box. At least one rotatable brush sweeps dust towards a suction port in fluid communication with the dust-collection box.

摘要： A self-propelled dust-collecting robot includes a main body having wheels, a dust-collecting unit collecting dust on a floor surface, infrared sensors each including an infrared transmission element that emits infrared light toward the floor surface and an infrared reception element that receives the infrared light reflected at the floor surface, and a controller controlling the wheels on the basis of a reflectance of the infrared light obtained from each infrared sensor. The controller, during running, determines whether the reflectance is higher than or equal to a predetermined threshold value. Upon determining that the reflectance is higher than or equal to the threshold value, the controller controls the wheels to perform an avoidance action with the position where the reflectance is detected being a virtual wall, thereby to control the self-propelled dust-collecting robot to perform cleaning within a cleaning range defined by a reflection member.
