3-axis camera gimbal for GoPro (gyro stabilisation test)

[khymlawrence]

what gyro did you use?

[squawk7777]

omg its the hands from the adams family!

[TheAlexdrift]

make more plz with it on the plane

[rc18trocks]

reminds me of Glados from portal :)

[nil0bject]

do you use ardupilot?

[daign]

this thing is trash. the plastic is horrible and brittle, the parts do not fit together, the servo slots do not fit any servo that I tried (futaba hitec jr). This is better off as a youtube demo than in reality. On a quadcopter it eats servos and puts entirely too much strain on the servos.

[zackmctee]

wow man! I hope you make the decision to sell these!

[rtsdrums]

When using on a multirotor, how would you mix the 2 servos for roll if I used 3 separate gyros?

[skrulonair]

all good but this is to expencive as whole gimbal cost about $100 + PP

[crzycody4lyf]

could this be used for something like this:

/watch?v=gFInmUssBDA

[Tryden93]

man would love if you sell sth like this

or make a tutorial how to build one of these

thanks and keep the good work up!

[WheelDweller]

Ya know, about 10 seconds of this would have been enough. What piqued my interest was the chance to see the unit being disturbed, and the resulting video from it.

Do you have something on that?

[helixdesign]

@djentangle: I actually developed all the electronics myself, including the 3-axis gyro. I also wrote my own software to mix and control the 3 axes.

I think there are two options - either put the gyro on the camera itself. However, I found that if the gain is low the camera will lag a bit, and if the gain is too high it starts oscillating. The other way is to have the gyro on the mount (shown in the video. I think you'd need to come up with a custom gyro, as it requires precise control to work.

[djentangle]

I've been looking to make a 1 axis mount for the motorcycle, basically like the motogp gyroscopic camera, I've been messing with heading hold gyro's but haven't had much luck (cheap china knockoff gyros). can you tell me what gyro and if you have to have it hooked up to a rc receiver or can you just run batteries directly to the gyro which is connected to a servo? let me know,

[martcerv]

you should upload the gopro footage as well to see how stable it looks when your testing it.

[eladbari]

@martcerv yea, i have a hunch that it is not that stable. there seems to be some micro movements because of that electroic gear-or maybe its just a lag of the device- that will cause the footage to look jumpy. seems like it tracks great! but still i guess a mechanical device [not electronic] will do a smoother job. nevertheless, this thing looks cool! and it might need some more work to perform better.

[heng1]

Hi. cool thing but maybe try these servos: dunehaven com gs1

they are bigger but all the stabilisation is included already ;)

[repalmore]

Excellent, I was wondering would it be hard to add a roll axis to the assembly? Would it make the whole thing too heavy? It looks better than what I've seen some repraps produce but I still would like to have my own Mendel.

[helixdesign]

@repalmore - it's probably not too obvious, but this unit has a roll axis (using the two pitch servos differentially). It only does about 20-30 degrees I think, but I figured that this is enough for most applications, and it allows me to keep everything nice and compact.

In terms of printing - the laser sintering that Shapeways offers is way more detailed than FDM extrusion, even from professional machines. Also, the material is some form of engineering nylon, which is quite tough and flexible.

[Shapeways]

Very Cool, Thanks so much for sharing.

[AltitudeHD]

Excellent work !.............can you please post some video footage ?  Thanks.

[helixdesign]

@SCHM1ERN1PPEL - sorry, not yet... You can get the servos at Hobbyking (MKS470) or other places, and you can use a remote control with v-tail or elevon mixers to drive this as a 3-axis pan tilt unit. For the gyro stabilisation you'll need some 3-axis gyro and microcontroller to generate the servo signals. I'm planning to make available my board, but it's not ready yet...

[jagsaiyan]

@helixdesign Do let us know when a package would be available. This is neat! Especially for motorcycle ride videos if I can mount it somehow. :D
