Autonomous carriers or totes that include vacuum units are provided. As the totes move or are moved through a warehouse carrying products, they collect debris. The debris can be analyzed at the tote, and actions can be performed based upon the analysis.

A handheld air purifier may include a suction body provided with a suction surface having a first and second frame, a fan to suction air, and a filter to filter suctioned air, a bending portion extending rearward from the suction body to bend upward, and a handle extending further from the bending portion and held by the user. The second frame may be provided behind the first frame and may include a protrusion that penetrates through the first frame to create a gap between the suction surface and a garment being treated to promote a free airflow through the handheld air purifier.

A children's ride-on vehicle assembly comprises a vehicle body and an interchangeable cleaning apparatus. The vehicle body comprises a front end and a rear end. The vehicle body further comprises a seat sized for a child. The vehicle body further comprises a plurality of driving wheels and a steering assembly. The plurality of driving wheels is rotatably coupled to the vehicle body and adapted to contact a floor surface. The steering assembly comprises a steering mechanism for use by the child sitting on the seat of the vehicle body and a plurality of steerable wheels. The interchangeable cleaning apparatus is attached to the vehicle body and is configured to clean the floor surface while the vehicle body moves around the floor surface.

Provided is a robot including: a chassis; wheels; electric motors; a network card; sensors; a processor; and a tangible, non-transitory, machine readable medium storing instructions that when executed by the processor effectuates operations including: capturing, with at least one exteroceptive sensor, a first image and a second image; determining, with the processor, an overlapping area of the first image and the second image by comparing the raw pixel intensity values of the first image to the raw pixel intensity values of the second image; combining, with the processor, the first image and the second image at the overlapping area to generate a digital spatial representation of the environment; and estimating, with the processor using a statistical ensemble of simulated positions of the robot, a corrected position of the robot to replace a last known position of the robot within the digital spatial representation of the environment.

A device for covering a plurality of different sized robotic systems. The device can include a cover sized to at least partially fit over the robotic system; one or more sidewalls extended from the cover, wherein the one or more sidewalls is configured to removably engage with each of the plurality of different sized robotic systems; and one or more apertures in the cover and/or the one or more sidewalls. The one or more apertures are selectively positioned and sized so as to prevent obstructing the one or more onboard sensors of the respective robotic system when the device is in an assembled state with the respective robotic system.

A device for removal of a body fluid, such as a nasal fluid, and includes a collector vessel that traps and collects body fluid entrained in an air stream passing through the collector vessel. The collector vessel is made up of first and second bell shaped shell portions removably attached to one another and holding therebetween an internal, removable central member that temporarily reverses the direction and reduces velocity of the air stream.

The present disclosure provides a Foreign Object Debris (FOD) Collection Device that comprises a carriage, a hitch, a holding chamber, a powered sweeper, and a funneling component. The carriage moves along a surface. The hitch couples the carriage to an Automated Mobile Robot (AMR) such that the automated robot drives movement of the carriage along the surface. The holding chamber is supported on the carriage and comprises an opening through which debris are passable into the holding chamber. The powered sweeper comprises a movable brush supported on the carriage and is operatively connected to a power supply of the Automated Mobile Robot. The funneling component is located between the movable brush and the holding chamber and is moved by the powered sweeper along surface S such that the debris swept by the movable brush are guided by the funneling component into the opening of the holding chamber.

A vacuum clear and an electric motor module (100) therefor are provided. The electric motor module (100) includes an outer casing (1) provided with an air inlet (10) at a front side thereof and an air outlet (11) at a rear side thereof; an electric motor assembly (2) arranged in the outer casing (1), and cooperating with the outer casing (1) to define an air passage in communication with the air inlet (10) and the air outlet (11); and a silencer (3) arranged at the air inlet (10), defining at least one resonant cavity therein, and the at least one resonant cavity having a side wall provided with a throat in communication with the resonant cavity.

Provided is a robot including a chassis; a set of wheels coupled to the chassis; a plurality of sensors; a processor; and a tangible, non-transitory, machine readable medium storing instructions that when executed by the processor effectuates operations. The operations include capturing, with an image sensor disposed on the robot, a plurality of images of an environment of the robot as the robot navigates within the environment; identifying, with the processor, an obstacle type of an obstacle captured in an image based on a comparison between features of the obstacle and features of obstacles with different obstacles types stored in a database; and determining, with the processor, an action of the robot based on the obstacle type of the obstacle.
