Re: Types of Metal
We've had a lot of success the past two years using standard 3/4 in wide, 1/16th in wall aluminum tubing. It's certainly not adjustable without making your own holes, but it is very light, very strong, and very easy to work with. You can use hacksaws and hand drills to build the robot if you want to.
In 2007 Mark Johnson, one of our mentors, did the welding, while in this past year we used screws for initial construction, and then replaced as much of the screws as possible with glue and rivets. (though much of the robot is still held together by screws, for lack of time).
We've used 80/20 in the past, and the problems we had with it were weight and at least I personally never felt like the bolts and sliders held together quite as well as a good bolt and locknut or even screws. However this is just based on feeling, we didn't really have an issue with that. It's very nice for areas that need a lot of adjustment, so don't rule it out altogether.
The kitbot frame is also pretty decent for the most part. You can easily make a very successful robot out of it.
