Where did you get your robot's dimensions?

Hi everyone,

Just a short question: Where did you get your robot’s dimensions from?

A few possibilities as I see them:

  • Sketches drawn by component designers
  • Team measured everything after building it
  • You measured everything after building it

The reason why I am asking is that for me it was supposed to be 1, but it then changed to 3 and the ‘everything’ is still not true.
I have to admit that my team is not guilty of anything at all, we had a very stressy building phase with a lot of design changes and by now everyone is happy that our robot works just fine (me included).

LoL, if you saw us do our size check at VCU, you would have seen the half inch extra room we have in each dimension. :wink: Our bot was obviously designed with that in mind, but we constantly checked while building and changing desings.

The parts made with laser cut had a dwg original file, so I just imported with inventor. But all the rest had to be measured with rullers and other measuring tools.
And by the way, we used the metric system all the time. It’s the brazilian standard (I think most countries’ standard too) and so many dimensions had to be converted.

It doesn’t have to do anythng with the post, but I think that the SI (System International des Unites) is used everywhere except in the US (even in Britain, as far as I know, although they measure temperatures in Fahrenheit).
We had some fun on our robot: metric and imperial system mixed. But we all love Bosch extruded aluminum :-).

Oh, yes, 20x20mm extruded aluminum, 35 inches long. :slight_smile: Joy.

Measure the robot? What kind of silly idea is this?

Actually our team just made a base frame of 29’ x 35’…Then worked up from there.

As it turns out as we needed to loose about 6 pounds we changed it so that it is now about 29 x 30 (or so) and about a foot and a half tall.

Pure luck that it fit. :smiley:

It just fit?

How did you do THAT? We took one of the four stripes that come out of the extrused aluminum out; looks very good and sves weight (actually quite a bit).
