Systems, devices, and methods for docking a mobile robot to a dock using distinct visual fiducial markers on the dock are disclosed. A mobile robot system is provided that includes a dock and a mobile cleaning robot. The dock includes a first fiducial marker in a first plane on the dock and second one or more fiducial markers in a second plane different from the first plane. The mobile cleaning robot includes a visual system to detect the first and the second one or more fiducial markers, and a controller circuit to recognize the dock, and to determine a pose or heading direction of the mobile cleaning robot based on the detected first and the second one or more fiducial markers. The mobile drive system can adjust its heading direction, and drive to the dock according to the adjusted heading direction.

Systems and methods for visual docking in an autonomous mobile robot

The present disclosure provides, in one aspect, method of controlling an autonomous cleaning robot, the method comprising: navigating the autonomous cleaning robot to a docking station; sensing that the autonomous cleaning robot is navigating to the docking station; increasing a vacuum power of a vacuum assembly of the autonomous cleaning robot to reduce an amount of debris from an airflow channel proximate to an inlet of a cleaning bin disposed in the autonomous cleaning robot; and then decreasing the vacuum power of the vacuum assembly of the autonomous cleaning robot.

Electrical connection for robot vacuum lid

The present disclosure provides, in one aspect, an autonomous cleaning robot including a body, a drive operable to move the body across a floor surface, and a circuit board mounted below an upper surface of the body of the autonomous cleaning robot. The autonomous cleaning robot also includes one or more electrical contacts, a base of each electrical contact being mounted on the circuit board and a contact tip of each electrical contact being configured to protrude through a corresponding opening in the upper surface, wherein each electrical contact comprises a double curved structure to allow the electrical contact to be vertically flexible. The autonomous cleaning robot also includes a hinged lid including one or more contact pads, the one or more contact pads being configured to contact corresponding electrical contacts protruding through the upper surface as the lid is opened or closed.

A mobile robot includes a recessed well in a top surface of the mobile robot, at least one capacitive sensor underlying the recessed well and having a first region and a second region, one or more mobility sensors, and a controller coupled to the at least one capacitive sensor and the one or more mobility sensors. The controller is configured to determine an operating status of the mobile robot responsive to output signals from the one or more mobility sensors, and selectively disregard an input at a first portion of the recessed well corresponding to the first region of the at least one capacitive sensor based on the operating status of the mobile robot.
