Looks good, Nick. Can you add a picture of the blimp controller board and link to your main page in this post? It's not really useful as is ;-)


What's a "tank controller"?

Tank controls? To turn you reverse the thruster on the inside of the turn.

So that's what its called!

thats the term we used in the army when we'd turn our bradleys in place. one track would would reverse direction, much like you're describing with your thrusters. i hope it's a more graceful maneuver in the air!

When flying in RC mode it works great, but when searching for the beacon, if the blimp gets confused it just spins in circles. Part of the problem is the sensitivity of the IR sensors. Most of the time the front 3 sensors receive the same number of pulses. We had to change our decision making process to going the opposite direction of the least number of pulses.

If I were to redesign the blimp, the direction control would be more heading hold style. When the direction of the beacon is found, it would try and hold that direction by pulsing the thrusters until a new decision had been made.
