So our current design uses 4 wheel mecanum drive. We have the tough boxes set up in the standard gear ratio of 12.75 to 1. We are using 6 inch wheels....Not sure how fast it will go...We have only used 8 inch sticky wheels in the past, or the slippery wheels we used for lunacy.
The arm in its current design has a maximum reach of 8' 8" not including the gripper which adds a few inches. We are hoping to squeeze a few more inches out of the sliding mechanism and to make the arm a few inches longer, but we were not originally planning to go for the top row. (last year we tried to do everything and ended up doing nothing much.) We would love to do more, but we currently only have access to a band saw, drill press, welder, and angle grinder. :-)
This is the tower that our arm sits on. it is 1 inch aluminum that we are drilling 1/2 inch holes in.
This is the arm, we are using a 60 tooth sprocket to turn it. We figured out a way to use the key shaft to couple the sprocket to the arm so we won't be using the set screws as depicted in the model. We should have updated pics by the end of the weekend. We are using the slides to extend the arm. We had to cut 4 inches off of the ends of a 3rd slide to give us 28 inches of travel.
Here is an exploded view.
This is how we are mounting our jaguars. We are doing this so that each motor is a unit
