Wheel Design

The wheel design has been completed.  The wheels weigh 0.30lbs each and construction will begin tomorrow.

2010 Wheel Design

Build Day 4

At Team 254’s lab today, we had an extremely large number of people working hard to complete some common objectives.

In the manufacturing department, several students continued cutting stock for the bearing blocks.  Many of the bearing blocks have already completed their primary operation on the CNC mill.

In the design department, a very large group of students worked downstairs all afternoon to continue to develop prototypes for ball launching devices.  Some have been modified and improved to be tremendously more powerful than their previous states.  Upstairs in the CAD department, a small group worked hard all afternoon to CAD the Drive Gearbox.  As of 10:00 PM, the gearbox shafts are mostly done, but still need to be toleranced, which will be completed tonight to finalize the shaft drawings.  In the morning, the drawings will be sent to 968 and Pacific Precision for the shafts to be completed this week.

This week, the design team will finalize the gearbox and design the drive wheels so that the gearbox plates can be manufactured by Team 233 in Florida.  The manufacturing department will continue to manufacture the bearing blocks and will move on to the wheels once the bearing blocks are completed.

Build Day 1

After returning from our Kickoff meeting at Bellarmine, Team 254 returned to the lab to start field construction.  We sorted through the carpet to find the biggest and least worn continuous pieces and lay them out.  They were then seamed together with carpet tape.

We also constructed one of the field “bumps” from the official FIRST drawings using 3/4″ plywood.  We then proceeded to place different configurations of wheels on robots and roll them, unpowered, over the bump.

We’re currently looking into building a powered drive train for 8 wheels with rigid frame rails for additional testing.
