Re: the firefly effect
These past few days the robot has been moved several times to various indivudual's houses. Each time, we lost a little weight. Our first year, a nutdriver was dropped into a piece of square aluminum tubing. It stayed there all through competition until sometime the next year.

Re: the firefly effect
only thing that i know of that we have dropped off were lots and lots of metal shavings, we did drop the frame off of the table while we were working a few times but everyone always caught it before it went completely off

We don't have any quarter-inch nuts left at school--not because they kept falling off during crashes but because we actually used them up! |
Re: the firefly effect
We *always* end up with random T-nuts falling off of our robot.

Re: the firefly effect
our robot took a beating every time it came down the ramp. we had a few bolts come loose, not to mention part of the camera flew off. afterwards, we had to tighten just about every bolt on the frame (nice and tight this time).

Re: the firefly effect
This is where nylock nuts prove their usefulness. If you can deal with the hassle of putting them on, you never have to worry about losing them.

Re: the firefly effect
Oh.
ANd here I thought the Firefly effect was more like creating something fresh and original that will be unjustly ignored by the general public and eventually cancelled. Silly me. :rolleyes: |
Re: the firefly effect
well that too . .

Re: the firefly effect
So far, the only resemblence our robot had to the Serenity was the camera module puking off the CMUCam board when our shooters were turned on for the first time. (And the second, and the third, until we finally made a custom mount and screwed it in place :) )

Re: the firefly effect
We didn't have a lot of random nuts and bolts falling off our robot this year. This year we've used a ton of pop rivots instead of zip ties or bolts, so that has been a real weight saver. Careful inspection of the robot as it is being asembled, coupled with precise fabrication of high quality parts can usually help solve the issue of lots of random pieces of hardware coming off your robot.
Loctite and ny-lock nuts are your friends. :) |
Re: the firefly effect
We were testing our camera/shooter mechanism, and our motors were slightly out of sync...leading to some vibration...leading to the camera wiggling loose, falling onto the shooter, and flying off the robot at 14 m/s, only to bounce off of a table and land in someone's pocket.
That was when we decided zip ties were our friends. |
Re: the firefly effect
Our camera shot off it's position due to the vibation of the large rotating wheel of our shooter. It flew across the room crashed into the ground and fortunately it was undamaged.

Re: the firefly effect
This year we've had the basic nuts and bolts fall off our robot.
Last year we had our robot's arm fall off during practice, we were doing some driving practice the day after we got it working for the first time. We pick up a tetra and drive over to the goal, raise the arm and just as we're about to move into capping position the arm just falls clean off. As it turned out the bolts that held the arm to the rotating block were just threaded into 1/4 aluminum which just tore out, we later fixed it by bolting it through... it seem to work better go figure :rolleyes: |
