Re: Team Tuttle Park Rover
As I was drawing up my sketches I had another idea on the tricycle idea. Instead of powering two wheels I will power the one that I can point. The other two will just coast along. The steering wheel will have 180 degrees of motion. There will be a camera mounted to the steering wheel so we can see where it is pointing. I am also toying with the idea of having two drive wheels close together, like a tractor. Instead of using a servo to point them I will have them powered individually, and move them opposite one another to twist their orientation, then power them together to move the whole thing forward. I think my practical tests will help me to figure it all out. I will start with wood framing and move to metal as I finalize my design.
KISS
I have given myself a budget to play with. I am open to suggestions about how to spend it. I have a QuickCam that I can mount on the rover. Ultimately I will have at least two QuickCams and a 720P capable camcorder. I was actually toying with my idea of having cameras in stereo so we could take the images that they show and create a 3D image of the common parts of the view using simple trigonometry. But I am starting with just one.
The camcorder will be mounted on a pan/tilt device, and I will be able to control both the manual and digital zoom. It should have pretty low power needs considering that it will not need a video display. I will also have a tall boom, I want my comm antenna for talking to the lander to have the best range I can manage.
More later.
