Hello guys,
Just wanted to know how big are are some of your featherweights.
The one I have just CADed is 500mm wide by 350 length by about 100mm high.
Is that waay to big to have polycarb and steel?
Whenever I CAD something its always tiny or massive.:(
Thanks
Massacre's body is 330 by 310. the wheels, skirts and wedge will push it out to about 400-500 square. much bigger than i'm happy with . the body is 60mm high.
That's a very typical size for a feather. It's pretty hard to say if you'd be okay building with those materials, it depends on internals, design, and thickness. If it's a pusher though, yes, within reason that shouldn't be a problem.
As a general rule I'd aim to make robots as small as they can be (again, within reason) for the internals, as dead space is weight that can be used up more usefully elsewhere.
Tormenta 2 is roughly 400mm x 600mm tip to tip, which I'd say is on the larger side.
Conker 1 was 480mm wide, 380mm long and 270mm tall.
Conker 2 is a massive 560mm wide, 440mm long and 260mm tall.
Conker 3 is a mere 320mm wide, 450mm long and 180mm tall.
It varies a lot.
ok thanks guys.
Through a load of trial and error on this very subject I've found that you'll need about 400mm x 400mm of space to easily cram everything in. You can go smaller but its a struggle if your using the normal drill motor approach.
Seraph is 800mm wide 1000mm long and 500mm tall :mrgreen:

yes is the short answer (the items will physically fit). The long answer, it depends. You need to work out the dimensions of all your parts and work out if they will fit.
Make a card board cut out if it helps or do some cad modelling on the computer.

If it uses 2*15a Electronize stacked on top of each other, a tank style NIMH 12V battery / lipo equivalent and a staggered drill motor drive with 100mm wheels, it will fit.
But it can only run @ Robochallenge events translation spinning. No one else has insurance for spinners.
Thanks for the replies, very useful. I will work out the dimensions of the parts.
