Great thanks :)
Put some HDPE over antabuse. I think I overdid it a bit going for 6mm as it's not 200g :/ 100g for the armour and 100g for the innards. Thinking of going down to 3.. which *should* bring me down to exactly 150g.

I'm not surprised that's 200g It's not standard practice to make all your robot from the same thickness material. Try and build a robot with sides. Have 6mm side peices and then you can screw thinner panels to it. Also, maybes try for a wedge?
No, I now realise that :) I was planning to put thinner material on the sides but with the wheels external to it. Is that sensible? Or not? Would 3mm HDPE be appropriate? I am also planning a wedge but it was starting to look like it might not fit into the cube (and the weight was shooting up and up) so I just made it as a box for now.
Cheers
It's better to have thinner stuff on top because ants don't much attack from the top. I built Baby Hell and Bulletproof with 6mm side panels with the wheels inside, and 1mm top and base plates. Seems to have stood up OK thus far :).
Dave- is that 1mm polycarb of HDPE? That sounds like a good plan...
Bulletproof is polycarbonate. Baby Hell is 3d printed nylon. 1mm HDPE is a bit too bendy for a base.
Okay. I think I'll go for some 2mm polycarb for the base and top then. Then see what weight I have left for the sides. How do you fix the polycarb together in Bulletproof?
M2.5 bolts through the lid and base and tapped into the 6mm edge of the polycarbonate.
