• A frame constructed from Aluminum Tube Stock
• Team 254 typically constructs robot frames using aluminum square and rectangular tubes - Usually (1" x 1" or 1" x 2" Tube Outside Diameter and 1/8" or 1/16" Tube Wall Thickness)
• Team 254 welds tubes together to create a frame, but it can also be built using gussets, bolts and rivets as well.
• Some teams cut "pockets" into tubes, but pocketing tubes reduces strength greatly while not reducing a ton of weight. It is usually stronger and lighter to just use tubing with a thinner wall thickness.

Applications of tube stock frames can include drivebase, superstructure and manipulator frames:

• Team 254's Drivebase frames typically consist of two side rails connected by two or more ladder bars connecting the rails.  Some robot drivebases are closed (have ladder bars at very front and back of frame rails), while some have open fronts, as in the example at right.  Most drivebases have more than two ladder bars, with some bars in the middle to provide additional structural rigidity.
• Team 254 has built numerous superstructures and manipulators out of tube stock, including arms in 2004 and 2005, elevators in 2007 and 2008 and conveyor frames in 2006 and 2009.
