Our Robot weight woes.. to rebuild or not to rebuild

[coldfusion1279]

Silly questions to ask yourself first:

Are your scales calibrated?
Was your battery in place?
Bumpers on or off?

Moving on to my suggestions:

1. Allow me to reiterate the comment about wheels... Those look like they weight 6 pounds each! Replacing just 2 of them for omnis will save you several pounds. On this same note, omni's will improve your turning ability on carpet, which is a known problem with pneumatics.

2. Change out any aluminum for lighter gauge. Even your Al tubing looks thick. Change out the easy pieces first, then swiss cheese the rest!

3. Saw off the ends of bolts that are too long.

4. Tidy up wiring by trimming unnecessary slack.

If I think of anything else that's helpful, I'll edit my post.

Good Luck!
