 ====Tube Grabber====
-The tube grabber was a small module containing one motor to turn a unobtainium roller that would hold the tube in the tube grabber. The bottom of the tube grabber had flat plastic "fingers" that would support the bottom of a tube as it was being moved up and down during game play. When a tube was taken in, it'd be rotated upward at about a 30 degree angle so the tube could be easily placed on the rack.<ref name="CDBrandon">[[Brandon Adams|Brandon Adams']] [http://www.chiefdelphi.com/forums/showpost.php?p=599364&postcount=5 Chief Delphi Post]</ref>

 The tube grabber would move up in down via the tube elevator by 80/20 wheeled linear slides.{{citation needed}}

 The 80/20 supports that held the tube grabber in place as it moved up and down during game play was actually two long pieces of 80/20. Due to the sizing restriction at the beginning of a match, the two 80/20 pieces would be folded down in the shape of a triangle until the match began. After the match began, a pre-compressed pneumatic cylinder would push up the top half of the structure until it was locked in by a simple locking mechanism thought up of by [[Sunny Gupta]]. Pneumatics was no longer needed for the remainder of the match.
-The rope winch was a simple winch that was placed at the bottom of the robot with small CIM with a BaneBots gearhead and encoder.<ref name="CDBrandom">[[Brandon Adams|Brandon Adams']] [http://www.chiefdelphi.com/forums/showpost.php?p=599364&postcount=5 Chief Delphi Post]</ref> The rope from the winch went up to the top of the elevator, around a pulley, and back down to the tube grabber. The system only pulled on the tube grabber when it needed to go up, relying on gravity to pull it back down.

 During scrimmage, the tube grabber would get jammed in the elevator structure causing the rope winch to put a lot of tension on the rope, causing it to break. It was fixed by using a stronger rope.
 ===Drivetrain===
-The drivetrain of the robot was a four wheel drive with two AndyMark plaction wheels in the front and two omniwheels in the back.
