Robot Part Weight List

[Don Wright]

So, since this is probably the time of the season where teams are really starting to realize their designs and doing some weight calculations to see how close to the limit you are, or if x motor can power y device, or if your robot is going to tip over, I thought it would be nice to have one common location for weights for different devices. I'll start with what I have so far, and if people add to the list below my post, I will update this first post with the new parts. Also, I will show parts as verified if somebody confirms a weight. At least it will give you a starting point for weight watching (tm?).

Can anybody show me how to do a table, if possible?

BTW...NBD is Nothing But DeWalts

Also, at the end, I'm listing items I am going to try and find weights for by searching or weighing myself when I get to the lab tomorrow. But, if you have any information about anything, I will add it to the list. Thanks!

Team 234, Cyberblue has an excellent spreadsheet for calculating weight. You can download it here:

I can't seem to be able to open that Excel file... It just locks up. I did download it to my machine before opening too...
