Yes, I was talking about B. I was thinking that we would have preset controls to go to 0, 90, 180, and 270 degrees. We would turn at these speeds for the preset commands. We would do some testing and would have it programmed to turn at slower speeds when we turn the modules manually. Would this work?
I will try to calculate the torque needed, if i can find the coefficient of friction for the wheels we are going to use.
As for the pots, we have discussed sensors but have not planned mounts yet. I was thinking for mounting purposes that we should attach it to the shaft of the globe motor. I am kinda woried though about the wheels shifting into slightly different angles. Should this be a concern. As for other sensors, for the test system we are going to throw on as many sensors as we see a possible use for, for programming practice and to see what works well and doesnt.
