Yes, they are developing a similar vehicle. The design for our vehicle was actually inspired by the Draganfly III. We added cross beams, changed the motors and rotors, used different connections, etc., to improve vehicle control, payload capacity, flight time, crash survivability, etc.; our current aircraft is built from scratch. The Microdrones have a similar approach to control, though in my experience STARMAC is easier to fly. The goal of our project, though, is to fly research experiments.

Nice prototype but you are developing something seems just the same as the German Microdrones company. See in "Related videos" (?)

FUCK MAN I know. But hey, do u want to watch TV on ur PCYou'll get all the SKY CHANNELS there isAND from any country IN THE WORLD, on your pc screen!!!!Go to this website...frexis.*com/PCTV1.html(DELETE the *)check it out................its cool, i've got it myself.

Quite true. See and avoid capabilities are still required for air traffic though.

Wouldn't you simplify the problem quite a bit by just going for more altitude? Once you're even 300' above the ground, there aren't going to be many things in your way.-jcr

I've always wanted to get to that point. We're still working out the details of using lasers to detect obstacles. It's a fascinating challenge - how do you determine your path and speed to fly safely and acquire more information about your surroundings?

The energy density of fuel is what - a hundred times that of a battery? A thousand? Sure you'd have to offset that with a generator and motor, but I'll bet you could still get a 2 hour flight time with the same payload.

Perhaps. But the idea is to only carry enough battery to "run silent" for a couple of minutes, or to create a soft landing if needed.The advantage of converting from gas to electricity is that you can continue to use H-bridge controlled electric motors for the fine motor control out of your microcontroller, while depending on a much longer range fuel source based on combustion instead of chemistry. Honestly, you could get rid of the batteries entirely if you wished.

The advantage of a hybrid power train in cars is that the power demand in cars varies quite a bit, and the electrical system allows the use of an engine in its most efficient operating range, while the batteries are able to provide higher power on demand.When it comes to an aircraft, especially a helicopter, there's not much variation in the power demand in flight. Carrying the weight of the batteries would be a lose.-jcr

Freaking brilliant.So, how long until we can buy a commercial version of this robot to do small-package delivery over a 20 mile range?-jcr |
