Airship differential steering troubles

Hi all,

I'm faced with a problem - some friends and I are building a semi-autonomous airship (only a little one) and I've been given the electronics and programming to do, but I'm having trouble getting the pwm commands to work properly.

I'm using a little joystick with 2 pots to control it, the y-direction one controls the overall speed and direction of both motors and the x-direction one puts a left/right bias on them to turn the thing.

Here's the bit of test code I've got with just the one pot being used

symbol zero1 = b1

symbol zero2 = b2

Robotic Airship, some ideas :)

So i was looking at some flying robot designs, just out of curiosity. I ruled out helicopters and planes: they require too much precision in crafting and are too complex.. But alternatively an airship could probably be built :)

I've read on wikipedia that a square meter of helium can lift about 1 kg. A square meter means a big balloon, but a Kg is plenty of weight for electonics!

If you use light components, you can probably stay under 0,5 Kg or even less.
