A 3x2 propeller, another tuning of the PID & azimuth, & a lot of camera flashes got it up to 9 minutes. Previously, it was a 3x3 propeller. The motor stayed just cool enough.…
That there is the culmination of 30 months of off & on, hard work. The 1st stable hover of the Marcy 1 monocopter, under computer control. The last items were getting the takeoff as stable as possible, getting the altitude as stable as possible, aligning the azimuth as close to the camera angle as possible, & trying many PID values. Not only…Continue
This continues to move forward. Decided attitude sensing is required for what we need.
After some complicated math problems, finally derived an empirical method for determining attitude from video. It most definitely isn't…
A somber ceremony begins, as the machine which caused Major Marcy to sever all contact with us is dismantled & returned to its role as an aircraft position tracker.
The construction of an indoor test harness greatly…Continue
