Tasks This Meeting: 

Meet our new mentor - Brian Roe (former Battlebot builder and champion) and run some ideas by him.  We also hope to modify some of our existing pieces to make them more efficient.

Reflections For This Meeting: 

We all had a great time working with Brian, and are so greatful to have been able to use some of his equipment and expertise working on our robot.


Today we had the chance to go visit Brian Roe, who has an 1800 square foot machine shop in his back yard.  We met him at the Auburn Community Festival a week previous, and he expressed interest in helping us with our robot.  We of course were delighted to be able to work with him, and set up a time when we could come to his shop and work on some pieces.  The main purpose for going was to add a hole to some of our axle hubs, so we would have two screws to secure the hubs to the axle.  With out stancing, we were noticing the current axle hubs were not gripping enough, which was causing our robot to not be able to move up and down.  He suggested we add another hole at a 90 degree angle to the first in order to have a much stronger connection to the shaft.  He showed us how to use some of his equipment, and then the team took it from there and started working.  We had two team members working on drilling the extra hole, using his drill press, and two members working on threading the holes and testing to make sure the screws worked.  We were there for almost 5 hours, but got a lot done in that time.  We would like to give a huge thank you to Brian for letting us use his shop and spending the time to work with us!

We put two axle hubs on the plate, so we could drill two without having to take the time to replace each one.
