Theoratically, I should get a total of 14 kg throttle(3.3kgx4motors). I've come up with a couple of problems of which I have to solve. Havent got any parts yet.
Using a gyro with a numeric integrator i would, i think, get a drift, because the sample-period would be to long. but I don't know for sure. It will be a fairly large program, so I guess the sample time would be even greater than e forsee.Most of the problems are already solved, but the tilt-measuring is still a problem.Anyone have a suggestion of what to do ?If there is a different hardware for tilt measurement, I am all ears.
I was playing with the thought of using accelerometers, but since this is a dynamic object, which has an dynamic acceleration in addition to the "acceleration" the tilt wil give out, i would rather just use something to measure just the angles. an accelerometer will probably be used to measure the initial angles of the copter, because the intergrated gyro will have a logical 0 angle at the initial state of the copter. so if the copter is not totally horizontal both axes, it wont know what is horizontal.
simple question now: I have a small electric helicopter that heeps iself pretty level with no help from me. Just balanced and it hangs from the rotors I guess. Is there anything in that?
This post might get more responses in a hardware area by the way - not sure how you'd get it moved though.
I can not believe the stuff you can buy these days! You probably know you can buy two axis gyros from sparkfun but i would never have dreamed it. In their writeup it ref's RC helicopters so it must be a well-known application. Maybe you could fire a question to their customer support or see if they have a forum you could post in.
