maras Posted November 3, 2014 Posted November 3, 2014 Hello everyone, Its been a while since i last joined a lego forum, probably going back to the early 2000's when i was an avid lego mindstorms robotics invention system fan. Im not hugely impressed by the upgrade from RCX 2.0 to NXT/EV3, i think we're are limited to certain projects compared to what we had with the early generation of mindstorms. Anyhow I've always been a huge technic fan, so recently I've stocked up on technic sets: Excavator (42006), Mobile Crane MK II (42009), Pick up truck (42029) and I'm waiting to receive the Volvo L350F (42030), not to mention power functions and more pneumatics (personal favourite) to add to my collection. But ever since i was a kid one creation has stuck with me up until now, until just recently i managed to track it down. The Cyberarm IV created by Hideaki 'Joda' Yabuki. Now I'm only 25, so I'm hoping theres a few veterans here that remember 'Master Joda' and his amazing creations mixed with technic and Mindstorms, he was a legend of the lego world. The problem is the old mindstorms forum has closed down from what i gather so theres no way of seeing this masterpiece in action. By chance has anyone followed the instructions and made it? Im currently in the process of gathering all the parts to build it myself albeit substituting the 2 RCX's for power functions. Once i receive my 6 turntables in the post I'm just about ready to go. Regards, Maras Also if someone could tell me the parts labelled ® in the diagram it would be much appreciated. Im not too concerned if i don't use them but I'm intrigued because I've never come across them before. Any idea where i could find them? Quote
Jeroen Ottens Posted November 3, 2014 Posted November 3, 2014 These are the parts of the (red) micromotor Lego had years ago. Quote
maras Posted November 3, 2014 Author Posted November 3, 2014 These are the parts of the (red) micromotor Lego had years ago. Thanks for the quick reply, ill see if i can track them down and buy them over the internet. Might be hard to come by though. Quote
darksheep Posted November 3, 2014 Posted November 3, 2014 The part marked R is the micro motor and the other parts are special parts designed to clip on to the more and hold it. This the Top part and this is the bottom part . Quote

This the Top part and this is the bottom part . Unfortunately it doesn't look like ill be able to get one of them anymore, from all accounts they're pretty dodgy too and don't last long. Ill just modify a power functions motor to suit, not sure what the advantage is of using one of them. I can't imagine they would have much power. Quote
Balrog Posted November 3, 2014 Posted November 3, 2014 From just looking very closely (because the picture is so small), it might be possible to replace the 2 micromotors with a single regular PF M-motor. Quote

The micromotors are useful for their small size and very slow output which does not require any gearing. From my own experience, the reports of poor reliability are exaggerated. I have about a dozen of them and I've never had one stop working or break. YMMV. Quote

Agreed, i have the power functions remote were i can adjust the speed anyway so it wont be an issue at all.

They're worth a fortune now, id hang on to them for a few years and if you ever need to make a quick dollar you have gold right there. Quote
