Thanks for your answer! Actually all of them are not very impressive though it's the best I did come up with with the new motors. The first is walking and the second is light running with a 35 mm lens: I did use high gyro, though and I guess that this is just a wrong approach. I'm now trying with normal gyro sensitivity but have yet to reach even the performance level of the video again. PIDs where: roll: 18 0,08 25 pwr 145 pitch: 20 0,05 27 pwr 92 yaw: 18 0,04 27 pwr 156 I have the feeling that it's even more difficult to remove the visible foodsteps with lower P and D settings but at least I hope that running will look better once you got there, right?
Remember when your walking and bouncing the camera up and down the perspective change has no relevance to the stabilization of the gimble.. You have to move in a straight line to eliminate that..
To augment what Cedar says (and he's, of course, right), but think of it this way -- if you move sideways (aka translate horizontally), no gimbal can factor that out. Same for the up and down motion of walking (aka translate vertically). Walk like Groucho Marx did. It worked for him! It's otherwise known as "glide walking" -- practice until you can move fast carrying a cup of coffee filled to the brim without spilling any, then drink the coffee and pick up the gimbal! Andy
Like the S.W.A.T team. But don't drink the coffee....by the time you are ready the coffee is cold. Bill
Hi Tuukka, 25mm aluminium booms can be found at least in Bauhaus or Honkkari in 1mm wall thickness and some marine shops in Lauttasaari sells it in 1,5mm wall thickness. For me 1mm thick is working well. Best, Kari
Hi Guys and girls What is the slip ring for in this tilt cage? http://www.aliexpress.com/store/pro...em-with-1pc-GB85-motor/109347_1506184234.html And does it come to the other tilt boom, opposite the motor boom. So it replaces the dual bearing tilt mount. This one? http://www.quadrocopter.com/Dual-Bearing-Tilt-Mount_p_706.html
Has anyone had any issues with any axis have an offset and cannot fix it? I used mine perfectly fine yesterday but today, DURING A SHOOT, I powered it on and there was a 10-15 degree offset on the roll i could not fix with calibration, tuning, nothing. I ended up having to take away my 2nd operators pan or tilt ability, depending on the shot, and give it to roll so he could fix it and make the roll level. I ref lashed the firmware and reset the board and redid PID's but nothing is getting rid of the offset. Any suggestions? Also has anyone done the dual rod mount on the tilt like the Mövi setup and if so how did you do it, i really like that to keep things level and for balancing purposes.
I would check the IMU it might be off level. I use this. http://www.aliexpress.com/store/product/MV036-NEW-camera-tray-tilt-bar-KIT/109347_1480336372.html Bill
How does it attach to the tilt bars/tilt motor? Can it be used upside down to attach RED? You don't happen to have an image of it installed Bill?
Hi Bill, can you explain to me why your tilt bars are not 90 deg to the camera? Does it not matter like the roll bars?
Bill, wow looks great. I have a few questions. Is that a belt drive setup? What motors? The IMU looks like it is not level, is it just the camera angle?
Thanks guys @Jason 18lbs loaded. 5208 on the tilt direct, 5208 on the roll belt and 5108 on the pan belt. In order to balance the camera I had to go offset to the 90 degrees. The IMU is set that way in order the camera will point downwards. The customer requested that. here's another this one is 23lbs loaded. All motors are GB-85-1 Direct
Thanks Bill looks awesome. Are these cameramen the Hulk? My back and arms would give up, maybe I need to start lifting.
