Conveyor-1.1

Design

We determined yesterday that the next biggest issue to solve is the sprocket at the bottom of the conveyor that prevents the transfer of Rings. We think moving the sprocket forward and down in the direction of the chain so that the chain remains in the same place, but the sprocket is farther away from the transition point, to allow for more chain flex. To make this change, we can just move the sprocket shaft into pillow blocks on the front of its c-channel.

Conveyor-1.0

Create

The basic idea for the conveyor that brings Rings to the top of Mobile Goal Branches was designed in CAD, but its specific implementation was left to interpretation, because we did not know how the Rings would behave in real life. Now that we know flaps are the best overall at moving Rings, we can easily build the conveyor.

Intake-1.2

Design

While it might be hard to funnel Rings on standoffs as discussed in yesterday’s reflection, it still might work to intake a wider range of Rings then funnel at the very end as we shoot onto the Mobile Goal Branches, so we should still consider using standoffs, but in a wider configuration. To make this wider standoff intake with our limited chain attachment links, we used two sprockets connected with c-channels.

Intake-1.0

Now that the lift was done, it was time for the intake. Really, we wanted to try the rubber band roller because they had worked well for other game elements in previous years, but we still did not know how well it would work for Rings, so we decided to try multiple options.

Today we finished the lift. The only changes we made to the CAD were the two metal crossbars going between each side of the lift. We added these bars just so we can more easily test the intake roller and the ring conveyor. While mirroring the left side to create the right side, we did not put the bearings directly above the bearing for the bottom roller, because there is not going to be a motor on the right side, so we will not need an extra sprocket to transfer power to the conveyor.
