摘要： A robotic dust collector includes a body, a wheel, a wheel motor, and a suspension device. The body accommodates a storage unit to store therein dust and dirt sucked in from a suction inlet. The wheel supports the body. The wheel motor generates motive power to rotate the wheel. The suspension device includes a support member, a motive-force generating mechanism, and an adjustment mechanism. The wheel is supported rotatably about a center axis by the support member. The motive-force generating mechanism gives a motive force to the support member to generate a biasing force to cause the wheel to protrude from a bottom face of the body. The adjustment mechanism adjusts the biasing force based on a protrusion amount of the wheel from the bottom face. The suspension device gives the biasing force adjusted by the adjustment mechanism to the wheel.

摘要： A robotic dust collector includes: a cover plate that closes an opening of a housing; a first hinge member connected to the cover plate and having an insertion space; an elastic member disposed in the insertion space; and a second hinge member. The second hinge member includes a shaft part that is inserted in the insertion space and supports the elastic member. The second hinge member further includes a fixture part fixed to at least a part of the housing. The second hinge member supports the first hinge member in a manner that allows the first hinge member to rotate about a rotation axis.

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.

摘要： A rotary brush is easily attachable to and detachable from a body with less separation from the body during cleaning. A rotary brush attachable to a driving shaft rotatable about a rotation axis and including a protrusion includes a brush, a base to which the brush is attached, and a locking member that comes in contact with the base and the driving shaft to lock the base to the driving shaft.

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 dust collecting device includes a tank and a main body housing a motor and detachably attachable to an upper part of the tank. A handle and a cover are both provided in an upper part of the main body. The handle is capable of being raised and turned down around a handle rotation shaft. The cover is capable of being opened and closed around a cover rotation shaft and covers a housing portion provided in the main body in a closed position. The cover rotation shaft is provided in parallel to the handle rotation shaft. The cover rotation shaft is positioned closer to a grip portion of the handle than the handle rotation shaft so as to overlap with a part of the handle. The handle rotation shaft is positioned closer to the cover than the cover rotation shaft so as to overlap with a part of cover.

摘要： An autonomous cleaning device (1), such as a robotic vacuum (1), has an optical sensor (50) that includes: a rotary body (51) configured to rotate relative to a main body (2) about a rotational axis (CX); a light-emitting device (61) provided on the rotary body; a light-receiving device (62) provided on the rotary body; a cover (52) disposed upward of the rotary body; and legs (70) disposed around the rotary body and supporting the cover. In a cross section orthogonal to the rotational axis, at least a portion of a surface of each of the legs is inclined with respect to a virtual radial line (RL) extending in the radial direction of the rotational axis.

摘要： A robot polisher has, in a box-shaped body part having a round shape in a plan view, right and left batteries, right and left wheel motors (not shown), and a pair of right and left wheels. The right and left wheel motors are rotationally driven by using the batteries as power supplies. The pair of right and left wheels can be individually rotated forward/backward by the respective wheel motors. On a lower housing, at the front-side lower part of the body part, a pair of right and left brushes are downwardly attached, which rotate in directions opposite to each other during traveling while being in sliding contact with a floor surface.
