  Inverse Kinematics in Motion – Test Project

  Posted by Simon Ubsdell on August 22, 2013 at 11:31 am

  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.
