Hi everyone!


I’m trying to reduce the mass of my newest design. I’m having a few weight issues (feather weight) it’s a Swiss army bot currently, so the armour could be dynamic depending on the load out for example non spinner matches i could swap to something lighter to allow for my crusher.

currently with all the armour for the drive pod in 5mm steel I’m coming in at 10.5kg with lid, I’m aiming for 6.5
if i change the rear and sides only and the rest steel to poly 5mm I’m about 7.2kg in both instances the base is 3mm aluminium.

The problem arose when i stretched the bot 40mm to accommodate a larger battery pack.

I guess what I’m asking having never seen a featherweight up close what options are there and what kind of thickness should it be? i presume anything plastic hdpe, poly etc should really be 10-20mm?

I tried adding some holes in the rear but for the weight it saved it did not feel worth the compromise.
another option would be to reduce the size and find a battery workaround but id hate to get everything milled and find it needs dismatling completely to remove a pack!
