*realises he forgot that on every hydraulic robot he designed*

Would a LEM be good enough, or do you need specific ones?

If a LEM is good enough for Kan-openers pump, its good enough for pretty much every robot.

Thanks for that, off to change all my pumps from running on fairy dust

Name: Pain
Shape: Suicidal Tendencies
Color: Grey
Speed: 18MPH
Weight:220lb (100KG)
Armour: 7mm Hardox
Chassis: Titanium
Drive: 2 LEM130s 48v
Power: 12 x 9.6-volt NiMh Radio Controlled Car Batteries, each weighing 12oz.
Motivation: 6 inner 6.5inch wheels
Turning Cirle: 0
Dimension in CM (LxWxH: Unknown
Weaponry: 2 crushing pincer (Vertical) with 14 ton pressure at the tip Its powered by an (1) M-Mac M40 Hydraulic Actuator running at 12v , which can give 14 tonnes of pressure. The actuator has already been used in Robotic Combat, so this robot is realistic. The crusher is custom made out of S7 tool steel and heat treated to give it maximum strength , so it can rip through Titanium easily. For the weapon to function properly, the robot contains 12 x 9.6-volt NiMh Radio Controlled Car Batteries, each weighing 12oz.
Strenght: Powerful Crusher, good armour and speed
Weakness: Hates Spinners
Self-Righter: Invertible
is my vapour improving?

7mm Hardox is even more overweight than 10mm ti...I wouldnt use more than 4 or 3.2mm thick on a hydraulic robot with 6WD (it doesnt get any thinner)

Also, why are you stating batteries and voltage for a hydraulic actuator? I know they need electrical power to work, but the batteries powering the actuator fall into the category of safe to assume its there, so doesnt need to be stated and they confuse what the weapon is a bit.

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.

[joey_picus]

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).

[craig_anto]

ok point taken, 16cm body height

Isnt that the same actuator which needed at least 96volts to work?
