Re: 424's 2007 robot arm is very similar to 340's 2004 robot arm.
'if it aint broke dont fix it'
if something works and is reliable why mess with it. sure, the idea wasn't their own, but there are only so many things you can do with something. why reinvent the wheel.
aside from that KISS is something we all live by.
the more complicated, the harder they are to fix on the spot.
