The military has deployed 7,500 aerial drones; Chris Anderson's company, DIY Drones, has got 40,000. Every sort of copter and plane, as shown on the diagram below, is included in the universal autopilot chipset that DIY Drones sells (for $129). And this chip also includes features like geofencing, follow me, and fly by wire.
His presentation is well worth watching particularly when he discusses how drones can be used for precision agriculture right now, today:
Chris was just part of a really interesting 3-person panel where the other two presenters were Marc Raibert from Boston Dynamics and Steven Cousins from Willow Garage. Marc Raibert is CEO of Boston Dynamics (of Big Dog and Cheeta fame) and described how and why Boston Dynamics builds robots designed to work in rough terrain. He emphasized what Chris said earlier, that military grade technology was moving to the robotics industry at toy prices subsidized by DARPA and smartphone buyers.
Amongst other interesting things in his presentation, Willow Garage CEO Steven Cousins also answered the question about what is going to happen at Willow Garage now that the funding has stopped.
