Abstract:
A robot uses an infrared sensor including an infrared light source which produces pulses of infrared light. Optics focus reflections of the infrared light pulses from different portions of the environment of the robot to different detectors in a 2D array of detectors. The detectors produce an indication of the distance to the closest object in an associated portion of the environment. The robot can use the indications to determine features in the environment. The robot can be controlled to avoid these features.

Abstract:
A forward and backward compatible streaming protocol requires subsequent versions of the protocol to be purely additive relative to earlier versions. When a data segment is transmitted as a data stream, a first stream of data that is in accordance with a first version of the protocol is transmitted, with additional streams of data that are in accordance with subsequent versions of the protocol appended in sequence to the first stream of data. When a read module implements an earlier version of the protocol than a write module, the data segment is truncated to include only the data supported by the version implemented by the read module. On the other hand, when the read module implements a later version of the protocol than the write module, receipt of the data segment is terminated after the data supported by the version implemented by the write module is received.
Abstract:
The invention covers a robot cleaner that includes a cleaning unit and wheels to move the robot cleaner. The robot cleaner also includes a processor for controlling cleaning that is capable of estimating the size of a room based on distances between obstacles. The robot cleaner has several modes of operation that allow it to clean an entire room more effectively.
Abstract:
The invention pertains to a robot cleaning system that includes a robotic cleaner having a tactile sensor and a barrier unit, wherein the barrier unit is such that the tactile sensor on the robot cleaner is triggered by contact with the barrier unit. As a result the robot changes directions. The barrier unit can be adapted to avoid sliding, such as when the robot comes into contact with it. The anti-slide element can be projections such as hooks or rubber grommets and the like.
