Sentinel2 began from the idea of developing a office / home version of the autonomously patrolling robots for our industrial clients. The challenge lay in redesigning the Constellation system, the navigation technology, for a residential environment. Within working facilities, Constellation must often receive and send data over long distances and compete with other high-energy wireless communication systems on near spectra. The office / home environment offered the opportunity to shift Constellation's focus away from power and on to sensitivity. The resulting residential version of Constellation is low power system that can provide high accuracy with only few components. With Constellation's redevelopment complete, providing the core functions of intelligent navigation: localization, path planning and collision avoidance, followed easily. Sentinel2 derives its name both from its ability to maintain awareness of its location within its environment and also the base robot's typical application in commercial and industrial settings as a security and remote monitoring robot. As a package, Sentinel2 provides users with the base functionality of intruder detection, remote monitoring and telepresence as application modules, but also includes the Developer Toolkit, enabling advanced users to create their own tasks for the robot to serve. Moveover, the core technology is platform independent, permitting integration of the robot into any network system communicating via RS232 serial or Ethernet TCP/IP. The Sentinel2 package includes everything you need to deploy a fully autonomous intelligent robot in your office / home. Hardware components include 3 pairs of navigation transponders (additional transponders can be ordered separately), an intelligent charging station and the most robust robot platform we've developed. Once set up, the robot can patrol its environment and self-regulate its power supply, returning to the charger when necessary. These core functionalities support Sentinel2's included software modules: telepresence and remote monitoring. Also, included is its Robotnik Kit, a software development toolkit that provides the means to program your robot to serve new tasks and roles limited only by one's creativity.
