A method of confining a robot in a work space includes providing a portable barrier signal transmitting device including a primary emitter emitting a confinement beam primarily along an axis defining a directed barrier. A mobile robot including a detector, a drive motor and a control unit controlling the drive motor is caused to avoid the directed barrier upon detection by the detector on the robot. The detector on the robot has an omnidirectional field of view parallel to the plane of movement of the robot. The detector receives confinement light beams substantially in a plane at the height of the field of view while blocking or rejecting confinement light beams substantially above or substantially below the plane at the height of the field of view.

A method for energy management robotic device includes providing a base station for mating with the robotic device, determining a quantity of energy stored in an energy storage unit of the robotic device, and performing a predetermined task based at least in part on the quantity of energy stored. Also disclosed are systems for emitting avoidance signals to prevent inadvertent contact between the robot and the base station, and systems for emitting homing signals to allow the robotic device to accurately dock with the base station.

A method for energy management in a robotic device includes providing a base station for mating with the robotic device, determining a quantity of energy stored in an energy storage unit of the robotic device, and performing a predetermined task based at least in part on the quantity of energy stored. Also disclosed are systems for emitting avoidance signals to prevent inadvertent contact between the robot and the base station, and systems for emitting homing signals to allow the robotic device to accurately dock with the base station.

A control system for a mobile robot () is provided to effectively cover a given area by operating in a plurality of modes, including an obstacle following mode () and a random bounce mode (). In other embodiments, spot coverage, such as spiraling (), or other modes are also used to increase effectiveness. In addition, a behavior based architecture is used to implement the control system, and various escape behaviors are used to ensure full coverage.

Disclosed herein are through-the-lens tracking systems and methods which can enable sub-pixel accurate camera tracking suitable for real-time set extensions. That is, the through-the-lens tracking can make an existing lower precision camera tracking and compositing system into a real-time VFX system capable of sub-pixel accurate real-time camera tracking. With this enhanced level of tracking accuracy the virtual cameras can be used to register and render real-time set extensions for both interior and exterior locations.

Hybrid precision tracking

A system for generating automatically tracking mattes that rapidly integrates live action and virtual composite images.

A mobile robot operable to move on a surface in a room is provided. The mobile robot includes a shell and a chassis including at least two wheels. At least one motor is connected to the wheels for moving the mobile robot on the surface. A cleaner is operable to clean the surface as the mobile robot moves on the surface. A wall sensor is operable to detect a wall in the room as the mobile robot moves on the surface. A controller is operable to control the motor to move the mobile robot on the surface in accordance with a wall following mode and a bounce mode. In the wall following mode, the mobile robot moves generally adjacent to and along the wall in response to detection of the wall by the wall sensor. In the bounce mode, the mobile robot moves away from the wall.
