Hey,
It looks like axeadent will have to wait.Im going to build a simple clusterbot pusher to get some exsperiance.This is good cause i can drive one and my dad can drive one.Any objections to the name evolution......
Any recomendations on motors,batts ect........
They will be like mini storm 2s without the lifter......same sort of shape though.
Thanks.
Dan.
P.S axeadent will probably be ready for thinktank though.............i hope........

dan, i can currently building the same, my advice is go with 2x 9.6v drills in each machine with some 75 or 100mm wheels. robochallenge are very good for drills,wheels and make some really nice motor mounts.
i dont know of any past or present robots called evolution you get some such as mine prodigy evolution but not just evolution.
the biggest advice i can give though is weight!! you want it strong, but also light, i have had a lot of trouble with weight on mine, try and use polypro for side and rear armour with a mild steel scoop (if your having one) and some small box section for the basic frame, i wouldnt mount your motors opposite though as it would need to be wide, which means more material and then more weight, i would make a chassis out of wood and mount one motor at front left and one at rear right, i havent tried it myself but it would be interesting to see how it drove with this configeration. (i think little hitter is setup like is) or someone elses.
also get your scoop as low to the ground as possible, with only half the weight and 2wd you need to get under other machines to stand a chance. if you want any close up of one of my machines let us know and i can drop you an email.
thats my advice, perhaps some of the more experianced can offer another configeration.

Putting the motors in opposite corners seems a bit odd at first sight, but works well. I was really convinced it was a viable way of setting up the drive at last years UK Champs when I saw how well Little Hitter moved around the arena. My first try at a feather, Throk!, presently just a box on wheels, uses this set up and seems very controllable and is pretty good in a straight line. Its certainly allowed the robot to be very compact.

Thanks guys,
I like the idea of a motor on each end.
They will be the exact same shape as storm 2.
I was thinking of having 6 drill motors in each half of the cluster and having HDPE as armour-i heard it is the lightest avalible.
It might sound OTT and overweight,but i think i MIGHT be able to squeezzzzzzzzzzeeee them in the weight limit.
I might need 6 to,as it weighs half of a normal feather.
Where can i get polypro?
What do you think?

Oh and John on the music list on your profile.............wheres bloc party and Phil Collins?!:)

Backup to axeadent
Heh! Well, that list just scatches the surface really - Ive lost track of how many vinyl albums and CDs I have, but I suppose its the best part of 2,000, about three-quarters vinyl. Not that many by some peoples standards... Phil Collins? Er, well yes, I have his first two solo albums on vinyl and I still think the first one is quite good. Bloc Party are already mentally tagged for further investigation. Presently I seem to be getting into some of the Canadian Bands and artists that collaborate to form the Broken Social Scene, of whom Feist is one. Theres certain parallels with the Scottish bands that get together to make the Reindeer Section albums. Check out Son of Evil Reindeer...

will do!
Thats a lot of records!

i used to have something like 2500-3000 lps as well, and about 400 12 singles. Ive merged my collection with that of a fiend of mine who had even more than me, and we sold all the ones we had double. I bought a pinball machine from the proceeds. :)

Funny that.... people of our age do have a lot of vinyl/CDs but there again music stuff was better then :)

Well, there were no downloads back then, so if you wanted it you had to buy the physical media. Also I suppose music didnt have so much competition. No video tapes or DVDs when I was in my teens and no video games, computer hardware or mobile phones either - the dark ages! I dont know if music meant more or not, but popular music seemed to be part of the progress of popular culture - propelling it even. I dont think theres that sense of music driving forward into the future these days - pop culture progress seems to be measured by games console graphics and mobile phone technology.
Er, wasnt this thread about Axeadent? Still, if youre happy to have it veer off Dan...

I dont mind i raised the music subject anyway.

Oh I can remember getting together with friends, we would visit each others houses on a rotation schedule, with a selection of our discs and some munchies. The host would provide the drinks (lemonade or cola). It was a lot of innocent fun, having a gang of 10 to 15 kids at your home and playing your discs, dancing a bit but mostly listening and chatting.
Mind you, our house in particular was popular, due to our dad being a single parent and having to work shifts -which meant he would be absent every afternoon one week out of three- and us having a football table game, a sjoelbak (a game involving sliding wooden discs over a glossy wooden plank into slots), several air pellet guns and some musical instruments. But it was the discs really, listening together to your preferred selection of music... what a time that was !
I still have a respectable stack of LPs (33-1/3 rpm) and 45 rpmers (even a couple of real ancient 78 rpmers). If I could find a player that I could connect to my computer I could record them.
Heck, if I could find a player I could PLAY them !!

Theres more new record players at all prices than ever at the moment. The Pro-ject range is particular good value.

I started to record my vinyl via the computer - my amp had RCA output that plugged straight into the sound card of my computer. I recorded them digitally using Creative Wavestudio which is now (I believe) freeware. The resulting .wav files can then be burned to CD via Nero or other such burning s/ware.
Mind you - after 12 CDs I only managed to dent the collection as far as my 12 dance singles - there are the rest of the 12s plus LPs - about the same size as Leos collection. Mind you - the wonderful thing about digital sampling is that the scratches and clicks can be removed - I never knew how good one particular 12 sounded until I removed the sound of all the manufacturing faults (bubbles, dents etc) and then pushed the higher frequencies a bit :)

There are now also turntables with USB, so you can convert them to mp3 in one go, and edit afterwards.

For example:

Not ultra cheap, but certainly the cheapest decent USB deck on the market. The ones for £100 or so are relatively low quality plastic jobs and sound quality will not be good.

I hate mp3! Unfortunately I can tell the difference - even at a rate of 320 kbit/s :sad:

It just cannot do sub-bass thats the problem

Backup to axeadent
Im afraid I dont take MP3 and the like particularly seriously, although its useful for background music or in portables. Always sounds a bit fluffy and diffuse, as if there was something wrong with my ears. Low bass does seem to lack power and definition. CDs sound pretty good these days, but I still think a good vinyl record on a decent turntable is better. Unfortunately getting the music out of the groove involves proper engineering, which can never be done really cheaply.
Stu, youre an old fogey with your MP3s. The kids are into vinyl these days!

I had 2 Technics SL-1200 MKII turntables back then, but they cost an arm and a leg (1180 guilders, about 500 euros a piece). They will last a lifetime though, apart from changing needles now and again they never let me down.
So a turntable like that is expensive short term, but its return of investment is great.
As far as MP3s go, yes you miss some dynamics as opposed to vinyl or CD, however for the vast majority of its applications (bars/resaurants, mobile player, ringtones) mp3 is a fine solution. OGG/Vorbis would be even better but i dont ever see that becoming a standard. It has something you might like Karoline, variable bitrates. When the sound quality needs to be higher the bitrate goes up automatically, and down on parts where it is not needs (like silence for instance). High compression yet still high quality.

Another thing wrong with mp3 - Ive only got a CD player in the car :rofl: Plus the problem with music I like is that there are no silent bits :proud:
Back to getting the music out of the groove I never use filters and getting the blips out is a matter of taking time and removing minicule groups of samples of the offending displayed spike. The track I mentioned before was V4 Visions Jungle Bizznizz EP - a white label pressing made so hot that the vinyl must have almost boiled(!!!) hence it was full of dents and bubbles, keeping the damn stylus on it was hard enough and it took me all day to get it almost nearly right - Im quite proud of that clean-up job and it still sounds like vinyl.
