Nice work so far Giles, is all the aluminium there 2024 then? Should be tough as hell
Firm doing the CNC is in Ireland, so not local, but he's a good guy.
@Andy, some of the internal mounts are 6082, the claw standoffs are 7075 and the frame is all 2024.
@Maxamus, Mantis 2 will be somewhere between 13.2 and 13.6 I imagine, CAD is saying just below 13kg right now, with small wiring bits missing. 2024 is 2.78g/cm3 and 6082 is 2.71g/cm3, so the difference is minimal.
hmm ok as the info i got from here says other wise. meh it is the internet it's fully of lies

I've always gone by the ASM database. I've not encountered that makeitfrom website before, although I like the comparison thing.

yeah it useful. might be worth using the higher estimation as it is easier to add weight then remove it
Sorry to sound dim witted (i manufacture robots on the coffee table), but is it a case of you drawing it all out in cad and then sending the files to a company who then mill it / cnc it etc? So in effect if I learnt cad I could stand half a hope in hell at producing something like that?
Most probably yea. I still have to make all the standoffs shafts and gears etc on my lathe and do lots of other parts, but the main frames can be easily cnc'd or water jet cut and assembled. My first robot (spinner wedge) was all just water jet profiles bolted together with m6 threaded bars, definitely coffee table levels of assembly.
A few more images of frame and drive pods
