The new development environment consists of iRobot Aware 2.0 and a new Robot Developer's Kit. Both are aimed at developers who want to create add-on capabilities for the company's versatile PackBot robot. The PackBot is designed to accept a wide variety of sensors, control units and manipulators so that it can handle an equally wide variety of missions. Most PackBots are in use by the U.S. military, but some are entering commercial and municipal service.
