So, I’ll start off with this tid-bit: Total noob here. I have no idea what I’m doing.
I’m working on a film project and need to make the camera move on a curved 22 foot track at a constant speed. The curve of the track is an arc on the circumference of a circle that focuses on a couch in a living room.
The full shot is seven separate setups–different people, but same location. So, camera will move about three feet down the track, stop, set up new shot, back up a half foot, move forward for three feet, stop, set up, back up, etc. Once all shots are stitched together, it should look like one continuous shot with different people fading in and out of the scene.
My thought is to have a remote of some sort where I can program a key for the forward speed/duration and another key for the back speed/duration (robotshop.com/en/lynxmotion- … er-v3.html)
Total camera rig will be under 5lbs. Max speed I need is 0.3 ft/s (.2mph).
So, my question(s): will the above items do what I need them to do? Am I missing something? Is there an easier/cheaper option I’m overlooking?
You may wish to have a look at something like the RB-Lyn-684. It can move around a payload of ~6 lbs. Please note though that this payload would have to include not only your equipment but also the battery pack(s) and electronics’ weight, also.
We have plenty of other chassis available here, some of them very capable of moving large loads easily, such as the RB-Dfr-13.
You can have a look at 6 V DC (for on-board electronics) and 12 V DC battery packs here.
For the motor controller, you can probably get a dual DC motor controller and wire 3 motors (same side) on each channel for simplicity. Make sure to choose a motor driver that is powerful enough to provide all that current though! Please have a look at our motor controllers here. A favorite for these kinds of projects would be a Sabertooth R/C from Dimension Engineering.
Good luck! And once you get started, please post some more about your on-going project either here on the forum or on our project-oriented website, Let’s Make Robots. We are certain the RobotShop community would be interested in both seeing your project in development and also contribute ideas / help.
