Build Day 1 Meeting Minutes

• Ideal design would utilize a  rigid 6 wheel / 8 wheel structure
• Ideal design would also incorporate a mechanism that will allow the robot to traverse over bumps quickly
• Both teams are wondering on the usage of 8″ inch wheels. (Additional gearing)
• Recommended Protyping: Build 6″ wheel chassis on 6 wh/8 wh base
• Didn’t discuss ball manipulation mechanism
• Winching should be relatively easy
• The transmission should be the most important part of this game
• 254 disagrees to lifting up two other robots(Reasoning: 50 lbs of parts for 6 points)
• 254 recommends that we should winch ourselves
• 254 will test 8″ and 6″ diameter wheels on 06 bot.
• 968 will do CAD on wheel base distance with various wheels and distance from center to center.

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.
