Abstract:
An autonomous coverage robot includes a chassis having forward and rearward portions and a drive system carried by the chassis. The forward portion of the chassis defines a substantially rectangular shape. The robot includes a cleaning assembly mounted on the forward portion of the chassis and a bin disposed adjacent the cleaning assembly and configured to receive debris agitated by the cleaning assembly. A bin cover is pivotally attached to a lower portion of the chassis and configured to rotate between a first, closed position providing closure of an opening defined by the bin and a second, open position providing access to the bin opening. The robot includes a body attached to the chassis and a handle disposed on an upper portion of the body. A bin cover release is actuatable from substantially near the handle.
Abstract:
A power-saving robot system includes at least one peripheral device and a mobile robot. The peripheral device includes a controller having an active mode and a hibernation mode, and a wireless communication component capable of activation in the hibernation mode. A controller of the robot has an activating routine that communicates with and temporarily activates the peripheral device, via wireless communication, from the hibernation mode. In another aspect, a robot system includes a network data bridge and a mobile robot. The network data bridge includes a broadband network interface, a wireless command interface, and a data bridge component. The data bridge component extracts serial commands received via the broadband network interface from an internet protocol, applies a command protocol thereto, and broadcasts the serial commands via the wireless interface. The mobile robot includes a wireless command communication component that receives the serial commands transmitted from the network data bridge.

A confinement device for a mobile robot preventing the robot from entering a space or region in which the user would like to safeguard or to keep the robot bound within a given space eliminating travel into sensitive or dangerous areas. The confinement device comprises materials used to absorb
Abstract:
A method, medium, and apparatus of a self-propelled mobile unit with obstacle avoidance during wall-following. In the self-propelled mobile unit, a carrying unit may move the mobile unit by using a transmitted power, and a sensor unit can detect an obstacle and a wall, which may be respectively placed in front of and to the side of the mobile unit, with respect to a moving direction of the carrying unit. A controller may direct the carrying unit by generating a path along which the carrying unit moves according to a detection result from the sensor unit. Accordingly, the controller can direct the carrying unit to move while maintaining a predetermined distance (within a predetermined range) from the wall. If the sensor unit detects an obstacle, the controller directs the carrying unit to move in an obstacle free direction.
Abstract:
The invention is related to methods and apparatus that use a visual sensor and dead reckoning sensors to process Simultaneous Localization and Mapping (SLAM). These techniques can be used in robot navigation. Advantageously, such visual techniques can be used to autonomously generate and update a map. Unlike with laser rangefinders, the visual techniques are economically practical in a wide range of applications and can be used in relatively dynamic environments, such as environments in which people move. One embodiment further advantageously uses multiple particles to maintain multiple hypotheses with respect to localization and mapping. Further advantageously, one embodiment maintains the particles in a relatively computationally-efficient manner, thereby permitting the SLAM processes to be performed in software using relatively inexpensive microprocessor-based computer systems.
Abstract:
A robot confinement system includes a portable housing and a mobile robot. The portable housing includes a first detector operable to detect a presence of the mobile robot in a field of detection, and an emitter operable to emit a first signal when the first detector detects the presence of the mobile robot in the field of detection. The mobile robot is operable to move on a surface to clean the surface and includes a controller operable to control a movement path of the mobile robot on the surface. The mobile robot further includes a second detector operable to detect the first signal emitted by the portable housing. The controller of the mobile robot is operable to change the movement path of the mobile robot in response to detection of the first signal.
Abstract:
In a robot control apparatus mounted on a mobile robot, movement of a human existing in front of the robot is detected, and the robot is moved in association with the movement of the human to thereby obtain path teaching data. When the robot moves autonomously according to the path teaching data, a robot movable area with respect to the path teaching data is calculated from positions of the ceiling and walls of the robot moving space or positions of obstacles detected by a surrounding object detection unit, whereby a moving path for autonomous movement is generated. The robot is controlled to move autonomously by a drive of a drive unit according to the moving path for autonomous movement.

Abstract:
A multi-function robotic device may have utility in various applications. In accordance with one aspect, a multi-function robotic device may be selectively configurable to perform a desired function in accordance with the capabilities of a selectively removable functional cartridge operably coupled with a robot body. Localization and mapping techniques may employ partial maps associated with portions of an operating environment, data compression, or both.
