The invention is related to methods and apparatus that detect motion by monitoring images from a video camera mounted on a mobile robot, such as an autonomously navigated mobile robot. Examples of such robots include automated vacuum floor sweepers. Advantageously, embodiments of the invention can automatically sense a robot's motional state in a relatively reliable and cost-efficient manner. Many...

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 ...

Each processor in a multi-processor system is periodically interrupted for preempting the current thread for servicing of a watchdog thread during normal operation. Upon failing to service the watchdog thread over a grace period, a system watchdog initiates an orderly shutdown and reboot of the system. In order to prevent spinlocks from causing fake panics, if the current thread is holding one or ...
