Here is 2767s gear intake. It rode on the bottom of the chassis, not many people saw it out from underneath the robot.
We mounted the two talons on the intake. It also had two photo eyes to tell us where the gear was in it's travel to the rear of the intake. In order to limit the wiring of the photo eyes back to the roborio, we used our sentinel board to receive the signal wires, its available at andymark. You can see the red board on the talon in the picture.
