My "theory" is that a Quad requires either an accellerometer or human input to keep from flipping. Any other possibilities?The IR sensor only works in some environments.
Insert QuoteYou're correct it can measure fast rotation. That's about 6 deg in a Hertz! ;-) Sorry 6 degrees in 1/50 sec. So we can stop it from rotating violently. Let's talk about Yaw for now. If it is spinning slowly, say 30 deg / minute, the ENC-033r will not be able to measure it. It will return a zero value. If we can't measure it, how can we stop it from happening? MarkT said this sensor is for short term control only. So we need another sensor. But some copters don't have another sensor. Am I correct?
If you don't grok 3D vector geometry it will be hard to code up the necessary algorithm.
