Re: RogueTwo Robots

yeh but at the point where Jamie wants to change the drum direction he will be upside down

or do you mean as he is upside down he could just try and hit stuff to flip himself the right way but not causing damage to opponents or the teeth???

Re: RogueTwo Robots

Maybe just run it in one direction and hit something to flip you back over? Remember that with your tooth design you won't really deal any damage spinning in the opposite direction...

That was what I was originally planning on doing, but the teeth aren't yet near to being made so I'm going to fiddle round with the design and see how they look with double-edged teeth. There are probably going to be lots of little changes made here and there though throughout the design and build phase so everything I'm saying just now may turn out to be bullplop in the end

Re: RogueTwo Robots

Jamie ive got two of these;

http://www.robotmarketplace.com/product ... NSTER.html both i think from memory are damaged though.. i put them in 360 and never really liked them- they didnt like running together in a dual brushless setup... your welcome to one if you want to try it out? - castle creations do a repair service, could be worth a look in, If your interested message me your address and ill get one posted of to you.

I have that one in my offroad racer with a Castle Neu 2200KV. It is also has reverse so no need to do the relay in between. I wouldn't run 2 of these together as they are not sensored and that can create serious timing issues. But as a single Brushless setup it should be fine. And if you think they have it easy in my car you've never seen me drive.

Re: RogueTwo Robots

Update - It begins!

Well it's taken longer than planned to get started on Drumroll II but at last got started on some stuff today. The materials for the chassis should be arriving tomorrow so main construction work will begin then, but today I focused on preparing the controller box that will house the Scorpion XL and Align brushless controller.

First of all, I called upon the assistance of an old friend, Cybot

This is a spare half-built one I acquired, still got my completed one up in the loft. But it's a good source of small fixings, components and connectors.

So I borrowed four M3 stand-offs to use to mount the Scorpion XL to the base of the box:


I got rid of the green connector blocks on the Xl and soldered leads directly in a bid to eliminate one point of potential loose connections:

I also borrowed some small connectors from Cybot to solder to the BEC and HV pins. It means if I need to connect up either function in the future I just put the other end of the connector in (pretty much a mini removable link) and I'm sorted.

Then I drilled some holes in the outside of the controller box to pass the connectors through and fitted a fan to aid cooling and also mounted the speed controller for the brushless on the outside too. With the heat it'll generate, it needs the more open space:


All I need to do now is mount it in the robot and connect it up
Oh, and still need to whack a Deans on the brushless speedo battery wires; I'm determined to do away with terminal blocks in this machine.

More updates as it progresses.

Re: RogueTwo Robots

looking good

i still have 2 cybots as well did you build the other robot too, looked like a vacum cleaner???

this is completely un related to your build but where did u get that solder from in one of your pics???

Re: RogueTwo Robots

Yeah the other one was called 'Tom' (points for originality)
I started building it, but for some reason I missed issue 74, which contained the first driver board, and so I couldn't attach all the subsequent boards until I had that one, but I never did end up getting it. I didn't have the magazines on subscription, I just got them set aside at my local WH Smith but for some reason, nothing ever arrived after issue 85. A bit gutted that I spent all that only to fall 11 issues short, but having said that, the robots have been sitting up in the loft for the past four years (at least) so it's not like I used them frequently. Not since I got my first combat robot working anyway

The roll of solder was given to me by someone who delivered supplies to my dad's work. I think the company was Kilburn Electronics or something (based in Paisley) and he said that it was a freebie, just as long as I whack a wee sticker on my robot with his company's name on it. But this was back in 2002 or something and a) I din't have a robot built until 2004 and b) my dad moved to a different job soon after. So yeah, a free, big-ass roll of solder of which I've only used about half so far

Re: RogueTwo Robots

I remember looking at some VHS tape long time ago, that had the cybot commercial on it.
So wanted it!

Re: RogueTwo Robots

I remember cybot.
Got all the way up to the motors. Mounted them backwards. Got bored. Left it.
I was young, mind.

Re: RogueTwo Robots

Update - It's allliiiiiiiiiiiiiiiiiiiiiivvvvee

I'm a happy chappy; managed to give Drumroll II a quick test drive tonight and it is unbelievably nippy. Was only doing it in my room so I couldn't get a decent shot of it driving in a straight line, but the spins on the spot illustrate how fast this thing is!

http://www.youtube.com/watch?v=l8u8sYpLRwM

And the best thing is, that was only on one battery pack and therefore half the voltage
Chances are though it will be nigh uncontrollable running on its full voltage so I'll probably have to crack out the dual rates and exponential setting.

So as you can see, the basic chassis has now been bolted together:



The good news is that it's square (give or take a millimetre or two) and very solid. Not weighed it on its own yet but if the end product is overweight there is room for weight loss. Still need to take a cut out for the belt to pass through for the drum which, along with mounting the brushless motor, will wait until the drum is fitted so I can get everything lined up properly.

Couple of holes in the sides to accommodate the drill motors:



And fit some home-made wheels:



Add a receiver, battery and wire it up:



And it was good to roll. It likes to wheelie (which will be eliminated with the weight of the drum and possible hardox outer armour) and I can't help but feel that, with the chunky wheels, it looks a little Tanto-esque at the moment

Anyway I'm pretty pleased with how quickly it's come together - it's taken a few days but only working a couple of hours a day. Still plenty to do on it but having it driving this early on means I can get plenty of practice in. Shouldn't need too much though, as the Scorpion provides some precise control. I still rate Electronize controllers but daaamn, the XL is nice

Re: RogueTwo Robots

Hi Jamle,

Haven't had chance to sort out your esc yet. Might have another pressie for you though...

Whats the height of the inside of the chassis? Just wondering if 360s old disc gearbox and motor will fit inside...

[RogueTwoRobots]

Re: RogueTwo Robots

No probs Dave. The way it's looking at the moment, I'd probably struggle to fit it inside! The current controller is almost right up against the drill motor when the casing of my electronics box is on. But I'd still be happy to give it a bash.

Another pressie?! It's not Christmas yet
Inside height of the chassis is 85mm. Just been looking back at some pics of your old gearbox to imagine if it would fit but can't quite judge it by eye.

Re: RogueTwo Robots

it's looking awsome so far :wink:

Re: RogueTwo Robots

Looking good Jamie, nice and solid and chunky Just wondering how those plates are actually fitted together ? Is it tapped Nylon ? Oh, and those wheels look good, I don't suppose you have any of that tyre material left ? That looks just right for what I want to put on Satanix's wheels (the current ones make transistion a bit bumpy)

[RogueTwoRobots]

Re: RogueTwo Robots

Thanks guys. The chassis is 15mm thick RG1000 (which is a regenerated grade of UHMWPE, very similar properties but cheaper) from Direct Plastics. In short, it is now my favourite form of plastic as it feels like Nylon but cuts like HDPE
It's all drilled and tapped together, 5mm high-tensile bolts. Only got 8 bolts in there so far just to get it together but there will be a few more added here and there.

That tyre is basically your standard mountain bike tyre but I picked it up from the local skip and it is a bit worn down, but that's quite good because it means the profile is quite flat across the way yet still has a good deal of grip. Would probably be ideal to eliminate the bumpiness in Satanix. I've got over half a bike wheel's worth left and while I want to keep a bit spare, there should be enough for a pair of Satanix' wheels. PM me your address and the diameter of your wheels (or the length of the current pieces) and I'll cut some and pop it in the post for you.
