Making a gps tracking dolly from a electric wheelchair, difficult?

Other Hardware Robotics

Hello, I am a indie filmmaker from Norway, who comes in "contact" with electronic diyin from time to time, but not on a regular basis.

I have an idea which I want to share with the good people here at the forum.

I have an electric two motor wheelchir made for terrain use.
This I have made remote controlled by connecting two servos to the two potmeters of the chairs joystick.
I have been using this successfully as a "infinity" dolly for some daytime filming.

And here starts my idea.

I want to step this up a notch by modifying this chair so that I can use it as a timelapse dolly driving by a gps track. It should be able to ramp up and down, pause continue and so on.. adding a pan& tilt head on this will make it awsome.

So does this sound feasible?

Here is a picture of the chair type, I have removed the chair on mine.

I appreciate any advice you guys might have.

Regards

Fredrik

Your Thinking something like these?

Yes, if you aren't real picky about accuracy. GPS tracking is +/- 10 meters or more. If that's acceptable, go for it.

There are atmega based multirotor drones doing gps waypoints. You might want to check out multiWii or MegaPirate Forums and their dedicated hardware . I've built an hexacopter with a 'Crius AIOP' flightcontroller, that locks position by GPS and other sensors in an area of 2 meters.
But be aware, that there is no collision control or obstacle avoiding code included ( yet ).
