Abstract: A robotic floor cleaning device that features a controlled liquid releasing mechanism. A rotatable cylinder with at least one aperture for storing a limited quantity of liquid is connected to a non-propelling wheel of the robotic floor cleaning device. There is a passage below the cylinder and between the cylinder and a drainage mechanism. The cylinder is within or adjacent to a liquid reservoir. Each time an aperture is exposed to the liquid within the reservoir it fills with liquid. As the wheel turns the connected cylinder is rotated until the aperture is adjacent to the passage. The liquid in the aperture will flow through the passage and enter the drainage mechanism which disperses the liquid to the working surface. The release of liquid is halted when the connected wheel stops turning.

Abstract: A method for automated mobile devices to identify and avoid dangerous edges or drop-offs. Rangefinder sensors are installed on the underside of devices to calculate distances to the work surfaces. Distances are monitored for changes greater than a predetermined threshold. Distance changes greater than the threshold cause the device to execute methods or algorithms for avoiding the identified area.

Abstract: The present invention proposes a method for robotic devices to accurately identify authorized users. Biometric data of users is supplied to the system through biometric scanners. Biometric profiles of authorized users are identified to the system during an initial set-up phase. Subsequently, users provide biometric data to the system through the scanners in order to be authenticated. Received data is compared to the original stored profiles, and when a match is found, that user is authenticated. In another aspect of the invention, a time-activated memory storage process is utilized to prevent malicious attempts to overcome the authentication process. Memory cells become writable in successive time slots, after which point the memory cells are converted to read-only. If a user is authenticated during a particular time slot, their biometric data is written in the available memory cell. If no user is authenticated, the available memory cell is written with junk data.

Abstract: A spherical or ovoid design for a robotic vacuum in which the housing of the vacuum also serves as the means by which the device moves. Steering of the device is controlled by adjusting the center of gravity within the housing. Perforations in the housing allow debris to be vacuumed into the device.

Abstract: A robotic vacuum wherein the housing of the system is cylindrical in form with two wheels of diameter larger than the diameter of the housing supporting the housing on either end. Larger wheels permit the device to more easily travel over small bumps or obstacles and changes in elevation. Furthermore, the design requires less power to drive the housing, so more energy is available for the primary function of vacuuming.
