Abstract	Nascent Technology reported on three main activity areas for 2005: (1) Joint NTC-MIT STTR work on multi-UAV collaboration, (2) development of the XS-series miniature autonomous helicopter, and (3) research in optic flow and precision vision-based position estimation. (1) MIT and NTC performed a ‘sub-urban’ flight test involving two helicopters jointly performing a beyond line-of-sight recon mission in which a ‘relay’ helicopter maintained LOS with both the ‘away’ (beyond LOS) and ground station. Mixed Integer-Linear Programming was used to command both vehicle positions, simultaneously respecting building and LOS constraints. MIT and NTC also began a new STTR program this year, to incorporate communication limitations in the coordinated search and track (CSAT) problem. To date, NTC has developed a unique real-time communication emulation capability that allows communication dynamic networking, routing, and associated delays and loss of comms to be incorporated into real-time simulations. (2) NTC has significantly upgraded it’s miniature autonomous helicopter product to make operation simple and trouble-free, while maintaining low cost. On-board power management, increased range, and fail-operable modes were added, as well as automatic take-off, landing and moving-map waypoint entry and ground monitoring. (3) NTC has begun developing various vision capabilities for autonomous vehicles. Optic flow for threat detection and urban navigation is being studied in collaboration with Centeye, Inc., which manufactures integrated high-rate optic flow measurement devices. NTC is also developing a vision-based landing system that uses a patented Moire pattern-based target to provide precision relative position information. Automatic station-keeping over an optical target has been demonstrated using a prototype of this target and vision system.
