u90photo?authkey=Nw-ajjOggR4#5189447697979536114This robot is in its early stages. construction.

There is still loose cables and all, but it should be pretty awsome.

i think everyone loved fritz's yellow drum machine so i realy wanted one and the only way i knew how was with lego.

my mindstorms robotics invention system will do all the drumming.

while my mindstorms nxt finds the object moves and records the sound.

please make a coment.

and fritz your my hero.... =)

well not really issac asimov is!

update # 1


ok... ive finished building this thingy this (actually quite brittle) little lego drum machine.

i havent started programming yet but it will be pretty difficult.

ive moved some parts around and taken some off but my biggest concern is that when it drumms on something it wont be loud enough because it doesnt use servos. =p so we'll just have to see.


id put up some more pics but i dont know how so if someone could tell me that would be great.

update #2

alrighty! i have finaly got a movie for you all to watch.

i dont really know how to embed it so i ll just give you the address.



its a little rusty at the moment. when it moves forward thats when it starts drumming it pauses, moves back and then so on. the only thing holding me back at the moment is that i need more rechargable batteries for it.

no point wasting normal ones.

update #3

this is my last update.

i am sorry to anounce that my robot had multiple flaws.

#1 structure. it was too weak and broke, ( can be improved )

#2 hybrid nxt and rcx. the two are based on different buiding measurements. ( nxt odds, rcx evens)

                    this put alot of building contections out.

#3 programming, the nxt was a little tricky in programming when i dont really use it that much,

                     plus i havent used the rcx in about 2 years!

#4 batteries. i will get a lot of posts about his but, the price on recharale batteries is pretty high and

                    is also pretty expensive to keep buying the normal non-recharables


well the robot will be scrapped and my idea can be continued by anyone who is willing to.

thank you for reading.

Hey Nebster,

Nice to see some lego in here (seem like everyone's got a picaxe these days - and they're not using it for mining :-). Cool that you built an NXT / RCX hybrid thing!

Like the other guys I can't wait to see video of the thing!

Keep up the good (lego) spirit!

Wacky! If you can get funk out of Lego, you can get funky with anything!!

well its not actually programmed or fully built for that matter so ill say a while.

=) drum machines should be the bots of this site!

When's the movie comin ?

Wow, that's looking pretty good. You did a good job of recreating the spirit of the YDM in Lego. Look at that, Frits, you've started a revolution! I'm looking forward to seeing some video of this thing.
