Re: Got Weight?
On the aluminum frame with the 1/4" holes in it, I used a Uni-Bit (one of those stepped-bits with wider rings for each size hole) to drill out EVERY hole to 5/16". We may need to go to 3/8", but for now this has worked.
Also, we drilled out nearly every peice of Lexan on the robot in cool designs and patterns. |

Re: Got Weight?
We took off about 20lb in 6 hours on sunday... it was quite the feat, but we learned some interesting things...
Like did you know that it takes 6 2"dia holes in 1/8" lexan to take out 0.1lb? And that 3 1 1/2" bolts with their washer & nut weigh 0.1lb? But it takes 50+ 1/2" holes in 1/16" alumnum to take out 0.1lb! Thats a very overworked drillpress! We took out as much unnecessary support, bolts, lexan, steel plate, etc as we could. Ashley kept track of how much we had lost each half hour, and it was cool to see the giant bucket of parts & hacked off pieces in the end. Now our poor little robot is all skin and bones! |

Re: Got Weight?
It's a little to late for this tip I use, but I design my least favorite (aka risky, cute but not worth much, or complicated) components to be massive. That way I have one more excuse to get rid of them.

Re: Got Weight?
if you bring your robot to a place with less gravity hmmm... lets say the moon for example you will be all set and plenty under weight.

Re: Got Weight?
It was mentioned twice before but my personal favorite tool in the Dremel. That means any screw that is too long gets the axe. Believe it or not, it does help. More so with the longer screws. Then again, our robot is all nuts and bolts so obviously, it would make a difference to us.
(Of course, we also swissed our robot. now we are comfortably under weight =D) |

Re: Got Weight?
Zip ties are your friends. I can't tell you exactly how much lighter they are, but they sure are much lighter than steel.
We were so concerned about weight, we even used smaller zip ties in areas of little stress. I love zip ties. |
