How Could I Improve...

[andrewj]

Ah, the things you are referring to are known as linear actuators. They are pretty much electrically operated rams. But like you, I know little about them I€™m afraid.

Otherwise, the stats now look pretty much perfect. No doubt someone will point out some more details for the pneumatics and batteries could be given, but as I barely include this myself I can€™t really comment.

Coinst

Not bad at all, very WX 6.0 style. :wink:

Lower the speed a little, add some battery details and it€™s fine.

Namie€™s Style

How low is low pressure? Again, if you have any details on ram sizes, that always helps.

Another almost faultless first attempt at a vapourbot.

Ah. I thought they were different things...never mind, and thanks for the help

I really need to edit Sir Spinalot. But Im having a hard time doing that.

How so?

I presume you mean 24 volts?

Otherwise, in my completely unqualified opinion it looks good, no glaring problems apart from the batteries...I think just saying what type and how many would be enough, maybe 4 NiCd packs or something like that.

A Sweet Summer€™s Night On Hammer Hill

Is the rear also curved as well as the sides? What sort of LEM€™s are you using - 130, 170, 200? Why are you only running them at 14v? To help the writers, use 25mph rather than 11m/s. ~25mph is also a little high for my liking, but that is personal preference. What are your skirts made of? What thickness is the steel you are using? How are you planning on changing the gears for the axe? How long is the axe and what is it made of? Can the linear actuated arm be used as a weapon? Why don€™t you just use the axe to self right you? Why do people still intentionally provide weaknesses in their stats for opponents to exploit?

Nice bot Dave!

Didnt notice that, lem 130s at 24 volts
To help the writers, use 25mph rather than 11m/s. ~25mph is also a little high for my liking, but that is personal preference.

I did say it was the max speed, just because a vehicle has a top speed of 100+ mph doesnt mean it has to drive at top speed all the time, its just nice to have a little extra power to escape sticky situations

What are your skirts made of?
I dont know, what do you suggest?

What thickness is the steel you are using?
Does 10mm bars sound alright?

How are you planning on changing the gears for the axe?
By the use of a switch on the controller

How long is the axe and what is it made of?
would you say 50cm is a good length?
And Steel for material. Although Im thinking about having a sword-blade attached to the arm itself.

Can the linear actuated arm be used as a weapon?
Not really,

Why don€™t you just use the axe to self right you?
The axe might get stuck in the floor.

Why do people still intentionally provide weaknesses in their stats for opponents to exploit?

Good point

Joey - Batteries were never my strong point

Batteries are pretty simple:

SLA: Sealed Lead Acid. Usually 12V sometimes 6V. High current output but heavies. For 24V you would need 2 SLAs, 3 for 36V. Most common are 7Ah, 9Ah, 12Ah, 15Ah, and 17Ah. The more Amphours the batteries, the heavier they are and the longer they can produce power. a 7Ah SLA is about 2.7 kg, a 17Ah around 7kg.

Nicad: Nickel Cadmium. 1.2V per cell, most common are 2200mAh and 3000mAh. roughly 85 grams per cell. you would need 20 for 24V, 30 for 36V. They cannot provide as much current in 1 pack as an SLA can, so you will need to put 2 packs side by side at least for Boshes, and for your precious lems and magmotors I would not attempt anything less than 4 packs side by side, or you will blow them up and burn.

Nimh: nickel-metal hydride. Its pretty much the same story as Nicad, but they keep their voltage up longer (also 1.2V per cell) but they cant give as much current as Nicads in one go. They are also lighter, around 65grams per cell. I drive 1 heavy on Nimh and i use for 2 boshes 3 24V packs of 3700mAh. Most used cells are Sanyo 3600mAh, GP3700mAh, GP4300mAh. They have the least internal resistance so they will not heat up as fast as other nimh.

Then there are Lithium based batteries but in fra rules only LiFePo4 will be allowed in heavies in the future.

The issue with that is that you gearing will not be as suited for acceleration or pushing. So you potentially only gain extra speed that you dont plan on gaining, while losing torque/acceleration that youll be using lots of, repeatedly...

Unless that gearbox has some fancy syncro mesh gears and a clutch, good luck with changing gears while powered... If you want to try it, go to your local hardware store, find a two speed drill and try changing gears while drilling....
