An electrically-assisted mechanical Braille writer includes a main solenoid to apply force to emboss Braille onto a printing medium, and advance an embossing mechanism to the next cell. A second solenoid engages a mechanical stop to prevent one or more embossing keys from being fully depressed, to prevent kickback from the keys mechanically coupling to the main solenoid. In unpowered operation, the mechanical stop is disengaged, and the embossing keys may be fully depressed to apply force to emboss Braille and advance the embossing mechanism. Accordingly, with electrical power, the user may supply a lesser amount of force and still fully emboss Braille cells, while without electrical power, the Braille writer remains fully operational.

An improved Braille erasure mechanism may comprise a reverse-embosser or impressing mechanism to imprint a negative Braille cell. A negative Braille cell is the reverse of a normal Braille cell, with one or more dots lowered or pressed into the printing medium in an opposite direction to the raised dots of a normal Braille cell. Because the dots of a negative Braille cell are lowered past the surface of the printing medium, they may be ordinarily undetectable to the fingers of a Braille user. Accordingly, by imprinting a full negative Braille cell on top of a Braille cell to be erased, all of the previously raised dots of the Braille cell may be lowered beyond the surface of the printing medium. Any further Braille cell embossed over the erased cell will be free from corruption, because any dot not used by the new cell will remain lowered and undetectable.

A mobile robot includes a body configured to traverse a surface and to receive debris from the surface, and a debris bin within the body. The debris bin includes a chamber to hold the debris received by the mobile robot, an exhaust port through which the debris exits the debris bin; and a door unit over the exhaust port. The door unit includes a flap configured to move, in response to air pressure at the exhaust port, between a closed position to cover the exhaust port and an open position to open a path between the chamber and the exhaust port. The door unit, including the flap in the open position and in the closed position, is within an exterior surface of the mobile robot.

A mobile cleaning robot includes a removable filter unit configured to receive a supply airflow generated by a blower and to filter debris from the supply airflow, a filter seat, a filter access opening, a filter access door, and a filter presence system. The filter access door is pivotable between a closed position, wherein the filter access door covers the filter access opening, and an open position, wherein the filter access door is displaced from the filter access opening to permit access to the filter seat. The filter presence system is configured to: permit the filter access door to move from the open position into the closed position when the filter unit is disposed in the filter seat; and prevent the filter access door from being moved into the closed position when the filter unit is not disposed in the filter seat. The filter presence system includes a lift arm movable between an extended position and a retracted position. When the filter access door is open, the lift arm assumes the extended position to receive the filter unit in the filter seat. Moving the filter access door from the open position into the closed position when the filter unit is disposed in the filter seat causes the lift arm to move to the retracted position.

An electric charging station for a mobile drive unit includes a frame that defines an interior volume of space. The frame is configured to carry an electrical charging unit positioned above the interior volume of space. The station includes a station charge connector that is configured to be in electrical communication with the electrical charging unit and is also configured for mating with a corresponding charge connector of the mobile drive unit. The station charge connector extends forward within the interior volume of space along a longitudinal direction that is substantially perpendicular to the vertical direction. The station charge connector is connected to the frame by at least one compliant mechanism that is configured to provide the station charge connector with positional compliance with respect to the frame.
