Green 3 Day 3 Reese's cups

We finished building the robotic drop arm and secured the bottle in the arm. We then attached an ultrasonic sensor to detect the conveyor robot. It then drops another robotic arm to signal for the conveyor robot to stop. The robot then dispenses the Reese's cups. It pours twice and then lifts the arm to allow the conveyor robot to move on. It then will repeat the process.
