Andrew Tridgell ("Tridge") is a well-known programmer in the open source world (Samba, etc) and one of the leaders of the APM dev team. His UAV team, CanberraUAV, will be competing in this year's Outback Challenge with an APM-powered Telemaster, and at the Australian Linux conference he gave a spectacular lecture about the team's strategy and the technological challenges in the competition.
This is a must watch for anyone interested in more advanced UAV functions. Tridge and his team have added a Panda board to APM to do image processing. This is a great opportunity to watch a world-class technologist explain the strategy they're using to try to win this competition.
