Robot Mounted GoPro on a Pan/Tilt Fixture

robot mounted GoPro FPVWhen I’m not busy with family, my job, working out, or this website, I also like to build robots.*  OK, technically this would be considered more of a remote-control mechanism, or even a prop, but “robot” sounds better.  It was recently on display** as shown above, literally hanging 15 feet in the air, and beaming “robot mounted GoPro” video to a projector in front of it.

As for the camera part, the “robot’s” two legs are controlled by two channels from a standard hobby RC unit.  The controller that I was using had four channels, and I happened to have a pan/tilt fixture from Servocity already assembled on my shelf.  Since at that point it was just a matter of plugging it in, I decided to add a pan/tilt capable GoPro camera to my robot.

For installation, I drilled out the pan/tilt fixture’s base to accept the 8-32 screws that I had available, and the GoPro was easy to attach with a 1/4-20 screw using the GoPro tripod adapter.  Interestingly, since my robot-thing was hanging from the ceiling, if it was tilted enough, it would cause the “MountainBeest,” as I call it, to swing back and forth.

It was definitely a fun time, but as cool as I thought it would be to have it hanging above everyone, apparently people don’t look up that often.  Either way, you can find more info on this contraption in the videos below. Continue reading

A Tricycle-Mounted Mobile Projector Mount

Hackett with his mobile projector mount

If you’re in need of a mobile projector platform, and don’t have a lot of money to spare, the video below by “hackett” may provide some inspiration.  He’d made a sturdy projector base for a van before, but this one is for use on a tricycle.

Although meant as “some sort of propaganda device,” this mobile projector mount could also be adapted to use with a very heavy camera.  The video is by no means a step-by-step tutorial, but more of a broad overview of the techniques for combining junk into something useful.  Adapting it for whatever else you have in mind (camcorder, GoPro, etc) seems to be totally in the spirit of this build.
