@222Doc Pretty nice Job.I am a lego mindstorm maniac builder too.Its an indefinite hobby I guess.I've built a similar lego arm that weighs 3.5 Kg.Although I've created its program, I still need enough time to watch it in action.These days i am going to have my first test.If everything goes well I am going to post a video sooner or later.Cya bro

the weight of an arm this long with a full soda can will tip over if the weight of the main body is not enough. Good question.

What motors did you use for the tracks?

Very impressive! HUGE! I noticed muti-speed transmittion also! May I recommend Nxt port splitter by mindsensors for all the sensors you will need!

what would be nice is a standalone rotation sensor for Pf and other motors that do not have any. we had these back in the rcx days. but a new one is needed with better resolution, oh and studdless too.

I have some questions if ya dont mind.
What are you using to control it?
Is it one nxt and pf battery pack?
Ya, I remeber the old rcx days, I actually used the old fiber-optics for rotation sensors by detecting pulses, but it was same as old rotation sensors at about 8 pulses per rotation.

testing mechanicals here is all PF(IR)8channel rc. i only have one hand set from lego but each two stick controler has 4 channels. the nxt in this film is for ballast and possition. it could run the drive and shift parts opening 3 ports from the PF.
i wish mindsensor would take on this to build a SMALL spot location rotation sensor. the size of the next motors is much to big for multi motor things. these new PF series are very well made for a toy.
