Re: Team 842,The Forbes Arm, Mach-1
It's a cool mechanism, but I'd like to give credit to team 60 for doing it all the way back in 2000, and carrying it on for years and years.
Granted, 842 did a different take on it by fixing the "wrist" sprocket and do a non 1:1 ratio. A clever way to use the same mechanism to get two rotations from one motor.
We've used it a few times in the past (with a 1:1 ratio) and always called it a "virtual 4-bar", I suppose this would be a "virtual uneven 4-bar".
