  Conveyor System:

  conveyor system pros and cons -

Design 1: Motors Only
Pros:
• Constant speed (assuming battery voltage does not drop dramatically)
• More space below the conveyor to accommodate the drivetrain transmissions and motors.
• Smooth transmission between different stages of the conveyor to the turret.
• Less possible states for the last stage of the design.
Cons:
• Cannot actually push the ball past the turret line. There needs to be a hand off so there will be a transition stage.
Design 2: Pneumatics and Motors
Pros:
• Need one less motor.
• Compressor is already on the robot.
• Higher handoff to the turret, goes past the turret line.
• Lower height than turret.
• When the supply is available, speed and force of ball feed will be consistant.
Cons:
• Takes up more space in the back bottom part of the robot.
• Requires ball to settle time into cup prior to firing.
• Lose contact with ball when going into last stage.
• Hard to manufacture the bowl for the launcher unless we buy it, work around could be square on point.
• Amy and Mr. Wolf feel that the linear action is more complicated than the rotary action.
