Functional Wind-up Robot
Eddie_Young posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
If you remember those little clockwork robots, which used to be toys and are now prized collection articles, than you will surely recognize my representation! I've been working on this for some time now and I'm proud to say that this robot walks as well as the real thing! It uses two pullback motors, a couple cogs (gears) and 623 LEGO elements to achieve (I only hope you agree ) both good looks and great functionality. The mechanism with the incorporated motors is made to fit exactly into the case and the case comes off all in one piece (I like my modularity). The mechanism for the legs is the most simple thing ever but making it was as complicated as any of my larger MOCs, because balance played such a vital role in all of it. You can still see it wobble as it walks (I find the wobble quite indearing though ) and a lot of work went into keeping it from falling when it does. I like to think this is my best work yet, so I hope you like it just as much enjoy!!! My Flickr gallery -
Hi all, since I like a lot old tin trains (Marx, Hornby) and in particular the clockwork ones, I always wanted to try to create my own clockwork toy train. The first idea was to use the yellow old clockwork motor from the Basic sets of the 80s. Unfortunately, its wheels were designed to accept tires, so double side border and no capability to go through rail switches. From this forum ("Moc Clockwork Steam Locomotive" from RSB04 user) I understood the possibility to change the standard wheels with train wheels and so I did, adding two rubber bands. I can say it works fine, with all its limitations. I ended up creating a "reloaded" 115 set with parts of the 70s I had around. All cars are very light, and I greased the axles with tamiya Mini4WD grease in order to eliminate noises and to reduce drag. On a circle track, it makes 1 and 3/4 turns. On straight track, it travels more or less 4 meters. It is a toy train, no more no less, but I wanted something more modern.

one day I was playing with an old wind up motor i had. I alwase liked the way these motors spun at a fairly slow pace for a long time, rather than spinning all their power away in the first few seconds after winding like most wind up/pull back motors do. thats when it hit me, sence it has such a long run time, just how far would it go on my layout? well, it worked better than you would think, so i carefully removed the road wheels the motor came with and fitted it with a set of blue/grey era train wheels (easier said than done). i decided id make the loco in the classic 80s style sence the running gear was from that time period. the end result? I tried to make it as small and light as possible, its smaller than it looks in the pic, fits in the palm of your hand. heres it is next to 7722 for size comparison. theres just enough room for a minifig in the cab. his head just barely touches the roof. well it was a fun experiment to say the least, the engine isn't exactly what you would call practical, but it works ok for what it is. its actually pretty suprising what it can do, really under rated motors these.
