This robotic sentry can be controlled by any remote device capable of browsing the internet, allowing you to monitor your home from anywhere in the world. Audio and high-resolution (640 x 480) video are streamed in MPEG4 format, and it can take still pictures and e-mail them to you; it has a two-way microphone and speaker that enable real-time interaction with subjects. Three wheels support its chassis, providing 360° of nimble movement as its camera boom extends to provide a wide field of view while surveying its surroundings. You can set the sentry with up to 10 paths for a customized patrol; it will move along a path, detecting and avoiding obstacles with its infrared sensor, and repeat the sequence until issued new orders.
