Howdy,
I got an R/C helicopter for my son's birthday, which
has been a lot of fun. It's one of these:

which has the counter-rotating props for stability --- two motors,
one for each prop, vary the speed between them and the helicopter
rotates, no need for a tail rotor, no gyroscopic prescession,
very stable, very nifty.
So I've been thinking about autonomous flight, inspired in no
small part by Larry's paraflite project.
Seems like adding a 3-DOF inertial measurement unit like the
one on jBot (MicroStrain 3Dm-GX1) could "balance" the heli in
3-D, just like the IMU tilt sensor on nBot makes it balance
in 2-D, and replace the human pilot, or at least lower the
amount of skill required. Also need some sort of down-looking
sonar or laser range finder.
Piece of cake, right? ;)
So, hmmm, replace the skill of the human pilot with a computer.
What exactly does that mean? What sort of skill is required?
So then I found this while hunting around on the internet:

boy do we have our work cut out for us...
