Abstract: A floor mopping assembly finding use in a cleaning robot. The cleaning robot may be remotely controlled or autonomous. In one embodiment, a feed roller lets out a roll of webbing or toweling, a take-up roller reels in the toweling, and a motor system causes transfer of the toweling between the feed roller and the take-up roller. A housing holds the motor system and the rollers, which are mounted in the housing such that the motor causes transfer of the webbing between the rollers. One of the rollers is configured to rest on the floor or surface so as to cause the toweling to clean the surface. In an alternative embodiment, the assembly also includes a pad to press the toweling against the surface, where the pad is mounted in the housing such that the motor causes transfer of the toweling between the rollers and between the pad and the surface.

Abstract: An apparatus and method for improving traction for mobile robots where traction is a concern. The mobile robot of the invention includes wheels and brushes. The wheels are mounted to the body of the robot. The brush is mounted to the body close to the wheels. When the wheels are rotating, the brush rubs against the wheel to get rid of debris on the tread of the wheel and cleans the wheel so that traction for the robot can be improved. An alternative way to improve traction by reducing slippage utilizes suction cups or wiper elements mounted on the wheel.

Abstract: An autonomous mobile robot system allocates mapping, localization, planning and control functions to at least one navigator robot and allocates task performance functions to one or more functional robots. The at least one navigator robot maps the work environment, localizes itself and the functional robots within the map, plans the tasks to be performed by the at least one functional robot, and controls and tracks the functional robot during task performance. The navigator robot performs substantially all calculations for mapping, localization, planning and control for both itself and the functional robots. In one implementation, the navigator robot remains stationary while controlling and moving the functional robot in order to simplify localization calculations. In one embodiment, the navigator robot is equipped with sensors and sensor processing hardware required for these tasks, while the functional robot is not equipped with sensors or hardware employed for these purposes.

Abstract: An autonomous canister vacuum cleaner has a cleaning head module, a vacuum fan module separated from the cleaning module, and a hose assembly connecting the cleaning head module with the vacuum fan module. The vacuum fan module includes a controller that performs navigation and control functions for both the vacuum fan module and the cleaning head module. Alternatively, the controller may be separated from the vacuum fan module and the cleaning head module, and can be mobile. The vacuum fan module and the cleaning head module each include a drive mechanism for propulsion. The cleaning head module includes a cleaning brush assembly that can be motorized or air driven. The cleaning head module may also include a microcontroller that communicates with the controller.

Abstract: A system and method of increasing the dynamic range of image sensors by controlling the exposure (either electronically or mechanically) of multiple images and optionally forming a composite image from the properly exposed areas of the multiple images of varying exposure settings. Certain embodiments of the system and method utilize image processing techniques to determine the various exposure settings and to form the optional composite image. The properly exposed areas can be used directly by machine vision applications.

Abstract: An interactive exercise apparatus engages a user's mind and body. The apparatus comprises an exercise mechanism and a steering mechanism for manipulation by the user to achieve exercise and to indicate a direction of motion. The exercise mechanism can be, for example, the steps of a stair climbing simulator or the pedals of a bicycle, preferably a recumbent bicycle. A simulated environment (e.g., an interactive simulated three-dimensional environment or an interactive simulated three-dimensional fluid environment) is generated by a computer and displayed on a display system for the user. The user manipulates. the exercise mechanism and the steering mechanism to travel substantially unrestricted throughout the simulated environment. The computer controls the exercise mechanism and monitors the exercise mechanism and the steering mechanism to determine user position in the simulated environment. The display provides a visual display of the user's position in the simulated environment.

Abstract: A braking system for an in-line skate wherein an additional wheel is connected to the skate product by a linkage. The linkage is designed to provide progressive braking force on the hub of the additional wheel. The additional wheel is load bearing and can rotate freely when the brake is not actuated. The braking system has a four bar linkage, a preload spring, a load bearing wheel hub and a skate wheel. The four bar linkage is made up of the in-line skate and three linkage bars interconnected in such a manner that they can move relative to one another. Attached to the linkage is a load bearing wheel hub which is attached to a brake wheel. A preload spring is attached to the linkage so that a predetermined force must be applied to the linkage bars before they will move relative to one another. The geometry of the linkage is such that relative bar movement results in a braking force being applied to the wheel hub and thereby to the braking wheel.
