Re: pic: Simbotics FVC Practice Field

I'll make some general comments based on our experience with the rotating platform. I'll note that we used all the correct hardware, and built it to the best of our ability.

With that, I'll start by saying that the entire assembly weighs a considerable amount. My "bicep calibration" would put it around 30lbs. There is a LOT of plywood there. Even with the solid plywood and the correct 12" lazy susan, the rotation is not very smooth/consistent. The plywood STILL warped on us, and it rubs slightly every rotation. A good solid push gets it around 1 - 1.5 rotations.

With our initial robot prototypes, we were able to get a couple different robots up onto the platform. I would say that the platform does NOT move/tilt any considerable amount. The platform also stays put, and you need to consciously try to rotate the platform. It doesn't just move when you tap it. Rolling the 2x ball into a vertical post barely moves the platform 5 or 10 degrees. Overall, we were successful in creating a robot that could manipulate the platform pretty easily. However, I wouldn't jump and say that the design was anything close to "practical." YMMV.

Feel free to ask anymore questions. Best of luck!

BEN
