I was wondering why people don't drill holes into their machines much to lighten them, they prefer to mill it down, or use 2wd compared to 4wd, is there a particular reason for this, are holes considered ugly? Are they particularly damaging to the integrity of a robot?
They just don't really save that much weight. Especially compared to, in your example, dropping 2 motors, wheels, esc(s) and al the material savings that go with that reduction in size and mounting pieces.
when things are peppered with holes it don't look too great.
nothing really wrong with them though
Makes sense, if I have to use them I'll have them in the bottom, kind of razer-esque.
It's better to alter and optimise your design before building if you reckon you're gonna be overweight. I saved over a kilo on the original Drumroll by chopping out large sections of Nylon and peppering the base with holes. But if I'd given the design more thought, I could have changed the material type and/or thickness before building to reduce weight and save myself from butchering the chassis. Having said that, drilling holes can be quite fun and you can mess about with funky shapes and patterns :crazy:
If mine is overweight, it will be because of a buffering tank, I don't know if I will use one yet. I doubt the armour will be too thick, its roughly .5ali base and .7 ali checkerplate top armour. I can't be too sure yet, because half the robot is in various boxes, in post offices! :lol:
5mm and 7mm ali? Or 0.5mm and 0.7mm ali?
If it's the second option, and if this is for a featherweight, you'd be better off armouring it in paper.
Your joking, right? :(
I'm not planning on using this in full combat events, no spinners! What sort of thickness would it need? Should I be looking at a steel compound?
Now I realise my mistake. I meant 5mm and 7mm, lol! :rofl:
Is that strong enough?
Its 5mm Ali Jamie, the old Daiske II :) Can't imagine a 0.05mm Ali baseplate holding everything together too well :lol:
Anyways, the armour should hold together right? I'm doubting myself now...
Also, will it need an L bracket to attach the HDPE sides to the base better? (With weight allowance it'll be armoured too, but for now its suppossed to keep the drive in place.)
