"It's moving, everybody!"

:p ;) ;)

Nice. Pokey enough, isn't it?!

[M]uuhh

25-01-2005, 04:15

i seriously doubt it was moved from a stop position. lol

DaveMark

25-01-2005, 08:32

what do you mean ? it did not move ??? u dont think the car moved ??

the car was stationary

nice... u'd have thought there wouldn't have been enough friction on the tracks to get enough grip! want a long distance shot of it working in daylight now just to confirm what it's doing :D - six

I am the guy building it - you think I spent all that time working on something to just fake it ? :confused: you are a strange lot !

Car moved from a stop position - you even see that on the tape - that tank weighs about as much as me - it requires two people to lift, theres a lot of grip on those tracks

hey james.... you already know i think you're a nutter ;)

nice work

:confused: you are a strange lot !
some people worry me with their lack of intelligence on here.. seriously.

have you never seen robot wars? i know it sucks but they show these things pulling trucks all the time, it's more than possible to do from a stand still.

btw dave, fog lights off, else i'll send a copy to the rozzers and they’ll be round to crush it. (drives me mad) :)

25-01-2005, 10:18

I like it, now all you have to do is stick a mini-ITX (or possibly nan-ITX if they get round to releasing it) system on it and get rid of the remote!

well actually, there is a complete telemetry system ready to go in - location is shown in real time on a laptop overlaid on an aerial map, also two live video feeds and an audio channel - all to a tested range of 3km :)

:eek:

you are actually planning to take over the world aren't you

sssssssssshhhhhhhhh dont let the others catch on

[M]uuhh

25-01-2005, 23:15

what do you mean ? it did not move ??? u dont think the car moved ??

the car was stationary

DaveMark
i was saying, i doubt the robot pulled the car from a stationary position, yes.
I did not say you’re lying or it’s a fake. But from the movie it does not look like it would heavy enough traction/grip to pull it from a stationary position. It is hard to tell on a dark movie like that though.

Anyway, does anyone seriously still watch Robot wars? I used to watch that show on BBC two but haven’t seen it for years! Is it still on?

BTW slarti, those robots on RW tend to have more than one 12v battery.

Jamez_Warner

26-01-2005, 00:05

no most tend to run at 24v which mine is currently being modified to run on for extra power. That small battery lasts under a minute under load

RW is done and dusted, no more are planned

I'll do a nice daylight vid next weekend

James

[M]uuhh

26-01-2005, 00:59

do those tracks have rubber feet?

rusty

26-01-2005, 02:27

no [M]uuhh - they are just metal tracks

i think you should consider butchering some old car tyres for strips of rubber and rivet them as rubber "ribs" to the track segments.

it would not only give you more grip on hard surfaces, but the rib effect would give you more grip in the soft and wet stuff too...

would be pretty easy as well.

just a thought

[M]uuhh

26-01-2005, 05:19

yeah you should put some feet on them. you will get a lot more grip, and a lot less slip ;)

26-01-2005, 09:51

I think that on Robot Wars, Sir Killalot was so heavy and powerful, it could pull an arctic.......

Jamez_Warner

26-01-2005, 09:55

yup, i intended to do that, just got to work out the best way of affixing the rubber...

James

[M]uuhh

26-01-2005, 09:56

think that on Robot Wars, Sir Killalot was so heavy and powerful, it could pull an arctic....... what? that made no sense...

ArTizan

26-01-2005, 10:11

You mean an 'Artic'? As in Articulated lorry i presume? Sir Killalot was so funny though, if you saw him coming for you, just run up some stairs :p

Or an arctic house? (iceberg?)

Jooster

26-01-2005, 10:42

yeah.... i meant as in an articulated lorry.

and stairs... his only weakness :p

DaveMark

27-01-2005, 09:27

Ok time for an update :), I noticed we had alot of doubts on this thred and people were saying no it cant pull a car (even when they had video proof:p)

Here is a 2nd Video of the car pull test (24v Verson, Pulling James as well as the car) This time we have more light.

Ok just posting this on behalf of my mad friend who is building the thing.

He has once again re designed it now he knows the track system works well

New Motors are going in:

http://homepage.ntlworld.com/davemark/images/motor.jpg

The Frame has been totaly re worked:

http://homepage.ntlworld.com/davemark/images/newframe.jpg
http://homepage.ntlworld.com/davemark/images/newframe2.jpg

This now makeing the whole thing longer by a foot and also a bit wider.

And here is a mock of what he is planning :)

http://homepage.ntlworld.com/davemark/images/mock2.jpg

There will be a 3rd guide cog to give the front end more of a angle to clime more :) (stairs for an example)

DaveMark

Jamez_Warner

25-02-2005, 13:01

OK it's getting there, expect some video footage within the next week

It'd be interesting to see one of you holding one end of the rope vs the tank!

Jamez_Warner

25-02-2005, 13:25

not sure there would be much contest ! but i'll try it - maybe I could use it to power ski in the snow :D

Colesy50

25-02-2005, 15:04

the cameras ready and waiting :) ..... cant wait ... ok me and james are wanting to do some push,pull and crush tests ,, any one think of some good items :) .. we allready have a 15" crt lined up :) ...

DaveMark

an iPod :D (just one of those display-ones you get in shops)...that i'd love to see!

or how bout a life-size cutout of George Bush?

Jooster

25-02-2005, 15:07

Like the choice of music in the 2nd vid... funnily enough i was listening to the killers as i watched the vid... and they synched up :eek:

Damian

25-02-2005, 15:09

lol....

Just seen this, lol.. is still looking good!

Nice one warner, maybe you could sell your car and drive it to work, or alternitively keep it in your boot until you get a break-down... could have an attempt at towing you home... lol... would need a fair bit of fuel?!?

:p

Would be a cool vid to see it pulling you on shki's across the snow, lol...
or have a trailor with a seat in for the driver and his remote control...
(lol, an original form of transport at least...)

Thats a monster!!

Looking nice.

Was wondering where the tracks came from. Did you make them from scratch or nick them off something else. Also what are those motors spec's. What gearing (If any) do you have.

Just Curious
Abnormal1

hey, the tracks come from www.rexnord.com - it's designed for bottle conveyors. Expect to pay over £400 new though when you include drive hardware ! best to try and find a factory throwing some out

Motors are rated at 800watts each at 24V, so 1600watts of power with both...

gearing is a 1:3 ratio with MOD1.5 spur gears in the gearbox next to motor, and then a further 1:3.5 from the sprocket through the chain to the rear drive sprocket

like so:

Wolvy_UK

25-02-2005, 21:00

If you ever skid on ice or snow and end up in a ditch, that would be pretty handy to have in your car boot to get you out. :)

What' s it' s purpose though, just the challenge making it, or some other reason ?

Jamez_Warner

25-02-2005, 23:58

erm yeah I do these random things all the time - just ask davemark !

It's just for a laugh, I've had a few tiny model ones and wondered how big I could build one. Also handy for shows and stuff

James

Jamez_Warner

26-02-2005, 00:00

first test resulted in some slight damge to the shed doors it broke through, slight problem with a contact inside the rc>speed control interface though - hoping to have some video for you this weekend
James

DaveMark

26-02-2005, 00:28

mm ok how mad is james :S.. well very !! :) i was quite sane untill i met james :) ... allways up for a laugh .. and never anything normal :) . like he says .. we should have some nice footage for you .. by the weekend ... ..

------------------------------------------------------------------------

i think im going have to start it ... :) we are starting requests for things to get crushed/ put in the ring with the above tank

here is the line up so far

Distruction List

15" CRT
Me (Tug of war)
Ipod (Display model only)
Full Size president Bush
Small remote controll tank

Any other suggestions please post and i will add to this list

ROFL qoute of the day :D

cool_dude

27-02-2005, 20:06

how much did that cost??

Jamez_Warner

27-02-2005, 20:47

currently cost spreadsheet is up to £900

27-02-2005, 23:01

Hey dont know if ive missed it, please correct me if not! But how much does the ATTV weigh?

DaveMark

27-02-2005, 23:08

i think i can aswer for him .. 140KG ish ... ... james correct me if im way out :)

DaveMark

Jamez_Warner

27-02-2005, 23:28

yup it's about that, having difficulty getting an accurate measurement though lol

James

Euphoria

28-02-2005, 09:03

Not exactly light then! Do you think it could pull the car with 4 of you in it?

Jamez_Warner

28-02-2005, 09:11

mark 1 pulled a car with two of us in - I'm going for something along the lines of two cars this time ;)

James

Zozart

28-02-2005, 09:48

That looks awesome. Nice job there! :)

Looking forward to seeing some footage of it being mean to a display-iPod, that'll be something to show my mac-loving friend.

Euphoria

28-02-2005, 21:51

mark 1 pulled a car with two of us in - I'm going for something along the lines of two cars this time ;)

James

How does it get so much power and grip to pull the car? What sorta motor is in there? Electric I'm guessing?

Jamez_Warner

28-02-2005, 22:10

yup 2 two 24V reliance motors, usually used in golf carts etc

3600watts peak on each giving a total peak power of 7200watts - or about 10hp
Obviously would soon overheat if kept stalled like this for any length of time !

car pull on version 1 needed me stood on top to get enough grip, but this one will have rubber pads for tarmac grip plus it weighs more than old one + me put together :rolleyes:

James

Euphoria

28-02-2005, 22:18

What do you use to give it all the weight? Kg weights?!!

It is an impressive machine! Bit more powerful that my TMAXX!!

DaveMark

28-02-2005, 22:20

It’s huge and made of heavy metal and thick metal track! No weights. Just big and heavy

davemark

Jamez_Warner

28-02-2005, 22:23

well consider each of the rear track sprockets are solid steel, the tracks are all 4mm plate stainless steel, 30kg of batteries and lots of angle iron etc. inside. plus heavy old motors

James

Euphoria

28-02-2005, 22:40

Fair enough! Still very impressive :) What gave you the idea to make one/it?

Jamez_Warner

28-02-2005, 23:29

had a smaller one first - fun to play with but couldn't handle even the smallest lumps of mud - so I thought big ! :)

Euphoria

28-02-2005, 23:38

Yeh but what gave you the initial idea to build one? Just outa curiosity!

Jamez_Warner

01-03-2005, 09:27

i just have these random thoughts - ooh that would be fun, lets build one...
dangerous I know !
