Inspired by Mark Spencer's very clever MacBreak Studio episodes exploring advanced linking behaviors recently, I thought it would be fun to try and build a robotic arm with genuine inverse kinematics.

So here it is (the second version is dressed up as a character arm):












In this case the rotation and translation of the upper and lower arm are being driven solely by the movement of the hand - it might seem simple but it's quite a complex issue:

Suffice it to say that with a lot of hidden nulls and some "computational" link tricks that I hadn't tried before it pretty much works.

I don't think that I'll be trying to build a full 2D character just yet - could be very time-consuming.

Still it's good to see that even pretty complex tasks like this are achievable in Motion - you'd think you'd have to have expressions to be able to do it but it just takes a bit of thought and planning and you can often get there.
