How Could I Improve...

7mm Hardox is very thick, and it may be a bit too heavy, but if someone says it is, thin it off by 3mm, but it looks as though it can handle 7mm Hardox.

About the dimensions, if you want it invertible, go for 20cm, or UNDER 20cm. 16cm is very low, 14cm is EXTREMELY low, and that height can allow you to be good against flippers and allow super handling.

I would go for 20cm in height because any less might make it tough for you to hold something. For dimensions, I would have:

L: 80cm (110cm including the bottom crusher lip) W: 80cm H: 20cm

Just some suggestions

Improving, yes. Ok, hardly.

With dimensions we mean how long is it, how wide, how high? Thats not someting you calculate, you design it that way.

You make some odd choices. 12x9.6V packs? How do you connect them? 5 in series, 2 of those series in parralel? what do you do with the remaining 2 packs? If not, you can never power the LEMs and even then 2 lines of 48V NiMh will not keep your robot running any longer than a minute.

A 14 tonnes hydraulic crusher on 12V is madness, you would need to draw so much current you will melt the batteries. 24V or 36V is much more feasible.

Says 48v so all 12 9.6 packs are in series, so its going to run for about 40 secs before its flat or burns out the batteries
Sorry mate not gonna work.

14cm body is perfectly ok, Biohazard is 11cm tall

If you are going to use a part, please try and get an understanding of how it works first. The M-Mac Actuator I presume you have seen in Dans stats and decided to use it. Well, in fact you seem to have copy and pasted it... I had to explain to him how it worked, and since that I dont think it has been used. Hydraulics require pumps and hydraulic fluid and are not run on electrics. I know very little about hydraulic systems, so perhaps someone else can help you out with this.

14cm high is not ok for a hydraulic crusher.

I think you just need something to run the pump (can be electric, petrol, or mysterious other power sources which you apparently have to talk to the FRA hydraulics expert to know about) and something to open the valves, and I think electric hydraulic valves come under the obvious, no need to state category.

yea it is Leo, TX-108 was only 16cm high and it fitted all hydraulic parts in

[leorcc]

I always include the arm in the height Craig. For me the height includes the weapon, I also do that with axes on my robot (I usually state height with and without axe).

ok point taken, 16cm body height
