Work in progress 3: Lego factory project v2.0

mag ik je vragen hoe je de power functions motoren met de nxt hebt laten samenwerken? of als dat niet kan hoe je ze om hun beurt hebt laten draaien?

@1chrisdaman1, de power functions motoren zitten via converter kabels aangesloten op de NXT's. NXT -> Oud 9V systeem en dan van oud 9V systeem -> Power functions

Ok, just one more thing: how does the first push thing know how far to go?

[DrywFiltiarn]

@WorldofMindstorms, none of the pushers you see in this video know how far they should go :) They just push until the part they push hits a blocking object. Only the rotation platform for the parts is aware of how far it should turn :)

This looks awesome! But how did you get the PF motors to work so accurately? Mine always take about a quarter of a second to stop after I give the command with the HTIRL. Are you even using that, or something else? But, anyways, it's awesome.

[DrywFiltiarn]

@WorldofMindstorms, the motors are not controlled through PF, they are connected by use of a PF->Old 9V converter cable and another Old 9V -> NXT converter cable, so that's more or less the trick. Also the motors in this robot don't need to be that accurate actually. They all are programmed so they would move further then they can so they will at some point just stall. Programming is all time-based. So if I know on average a movement will take 1 second, I just program it to do 1,5 second.

@DrywFiltiarn Oh, ok that makes sense. I thought you were using touch sensors or something. Thnaks

Functionality notwithstanding, this is beautiful as an object. If real factories had machines this pretty, maybe people wouldn't be so afraid of machines.
