Aaaah, I forgot about the technobots site, thanks!

The sabertooth 2*25 is confusing me, how exactly do I connect it to the reciever? Do I need to buy plugs seperately or do I configure it in a different way? The instructions on it are rather sparse.

you need to buy plugs seperatly.
look at the robot market place sabertooth 2x25 to look on how to set it up

Had a look and found a lead on technobots that looks suitable, ordered it too! Thanks.

Having trouble with weight, I have 7kg worth left for Chassis, and 100 cm by 300 cm area to fill. How do I go about solving this issue? All materials seem to dense, and I have no idea how to drop the weight of the internals considering they're already as low as they can be.

alot of foam

Sorry, I made that sound like I needed the volume filling, what I mean is, I have 7kg left and I have 100 by 300cm of armour that needs fitting and I don't know what would be viable materials at that weight, nor how I could reduce the current weight or size. I'm really at a stand still!

Edit: Solved the issue, I realised that I could reduce the weight, I'm ruddy tired and not thinking straight, sorry about that.

Are Trollied, Wasted, or Hammered available as Robot names, I haven't heard of them before but I thought I'd just check?

3m * 1m of armour? you could cover a heavyweight with that much

Going by your dimensions and design on page 5 you should only need about 4000 sq cm of armour max not 30000

You're currently looking at 2-3 mm of hdpe or 1-2 mm of polycarbonate/cfrp/gfrp and probably nearer the lower end of those ranges so not the best armour.

I didn't notice either that I'd calculated 30000 cm sq (so tired)
After my new designs (Page 5 is quite outdated) I have 3800 cm sq to cover with armour, and according to http://www.jindalstainless.com/toolkit/ ... lator.html 15mm HDPE at high end HDPE standard at directplastics - 96 g/cm^3 (checked the density on their data sheets) equates to 5.5kg rounded? One of us has done wrong calculation, and chances are it's me.

[daliad100]

Correct mass, missing a decimal point in the density though (0.96g/cm^3)

It's time to go to bed when you start designing robots with materials 6 times more dense than the sun as armour
