DEWBOT XII Portcullis Lift

Autonomous Portcullis & Cheval de Frise crossings on Newton

During our strategy development, we determined that DEWBOT XII needed to be able to go through the Portcullis & Cheval de Frise, both in teleop and autonomous. The Portcullis Lift is the mechanical device enabling this.

Portcullis Lift Objectives

• Raise the Portcullis and allow the robot to pass through
• Lower two sections of the Cheval de Frise, allowing the robot to cross over
• Perform these operations in either autonomous or teleop mode
• Perform crossing in such a way as to support scoring in high goal during autonomous

Portcullis Lift Specifications

• Raise the Portcullis - allowing crossing
• Lower (2) raised Cheval de Frise sections - allowing crossing
• Robot must cross Portcullis & Cheval de Frise facing forward (in the direction of shooting)
• Mechanism cannot extend beyond 15 inches from the frame perimeter
