Final Machine

The final machine that we made varied quite significantly from the first CAD that we drew up with the largest change being the design of the upper arm on the pole. The changes have been documented in an earlier post on the blog.

The final machine had a was driven by two planetary gearbox with gear ratios of 100:1. The torque was then transmitted to the axles through a gear ratio of 1.5:1. The axles were supported at the sidewalls and a bearing holder made from the aluminum stock that we were given.

We had to make some changes to the base plate to accommodate the size of the gears. Changes included shifting the positions of the bearing holders and changing the placement of holes for the motor mounts. Also, we had to make holes in the base plate so that the gears had space to rotate.

Here are pictures of the (almost) final assembled machine. We later added a rubber pad to the side slope.
