Hi Guys I have for some time been developing this flying camera, I say camera as this is a departure from the norm. Whereas most people make a copter that just happens to have a camera mount this is different. The operator fly's the camera and the uav follows the envelope that is required to stay within the shooting angles selected. I am new to arduino so any help is what I need most. It has a number of other features such as the ability to land on water.

    Can you direct me to where they are?

    As I move towards 6s batteries. That may well be the better option as the ESC's will end up living in those side panels. This is my other Flying Camera Mount. I call this one GUPPY. It has everything mounted on the internal floating 3692179927?profile=original beam system.

    @Denny,

    Sounds cool. I'd be thinking in terms of moving all the batteries onto the Camera module.

    Optic flow is demanding, one needs either powerful onboards or custom optic flow sensors (mouse sensor is optic flow, but there are (I think) better options posted on this site...

    The model has three batteries and the third one is not shown but yes it is fixed on a slider at the back of the camera mount to aid the final balance of the model and create the balanced beam effect on the mount. Those shocks are only the bump stops in the event of a hard landing. (standard off-road buggy components) they do not attach directly to the copter, but through an airbag platform consisting mostly of bubble wrap and Evo foam. This system can absorb all the vibration you can throw at it. Originally the camera platform was held in a magnetic field, but I felt that it could upset the Mag. so the design was changed to this. I did all of the flight testing with a KK blue board from Minsoo Kim, this was done to provide a bench mark test rig that would allow me to create the ideal aerodynamics platform without the use of Acc. or other stabilization devices. Having exhausted the possibilities of using MK I am now moving to the standard pre-assembled and tested FC from udrones so that the serious development of the electronics can begin. The camera mount has two imus. one for pan and another two axis one that is used for pitch and roll. They use 20deg/sec gyros from Invensense. These are currently integrated into much modified heading lock gyros from various sources that will eventually become a production item. I do however feel that the copters FC will move to 67 deg/sec gyros as the need for 300 is way beyond what is needed for a docile super stable platform, Anyone who has tried to use a 300 deg/sec gyro on the camera mount will have found the noise /oscillation problem that sets in long before you get proper stabilisation. As camera movements beyond 20 deg/sec only produce rubbish footage that can't be used, the 20 deg/sec gyro limits that movement and therefore helps the operator achieve good very stable footage. Post stabilization not spoken here Guys!!!! bGatti are you offering to help? This is a six axis system. the copter being the outer three axis and the mount being the inner high sensitivity part. Normally the outer part ballparks the inner system but here we are much more integrated.

    I believe you can improve shock performance if you move the batteries to the stabilized side.
    Also, visual stabilization should be mixed with gyro info to separate alt drift from pitch drift.
    Really this is optic flow, you might add 360 degree.

    Nice to see you are developing your airframe to suit a specific application Denny, rather than taking an airframe and adding a camera.

    Looks to me, "off the cuff" as if the damping shocks are coil over dampers used on R/C cars?
  • Bill Noyce March 8, 2011 at 1:20pm

    Sounds very cool. My camera mount UAV is still in design stage, but nothing quite as smart as you are developing.

    I would love to know where you sourced your damping shocks? I spent an evening online and i found nothing small enough for quadcopter purposes. Any info would be appreciatted.

    I like the camera counterbalance idea.  Maybe you could use the LiPo's as counterbalance weight.

    Could it be that those LiPos are a little too warm and cosy in those foam? pockets.  Do they need more breathing space?

    would be a big advance if you get it to work like you want it to

     

    which hardware do you want to use?

    which IMU?
