I'm looking for a good solution for creating an IK rig that behaves like a 6 axis robot arm like one would see in a modern car factory. This means each rotation axis would be heavily constrained to it's own rotation axis.
My target that the rig will follow is a matchmove so it needs to follow it exactly. In theory a six degree robot should be able to follow any point in space, but the math escapes me right now. Have any of you done something like this? Curious to see what's been done in the community.

Thanks in advance,

I'm having a hard time wrapping my head around something so I thought it best to ask the experts out there.

We're about to do a project where a rigid object ( like a box or a tea kettle ) is floating weightlessly in a room. It is being blown around by wind and bumping into objects as it goes. What we would like to do is loosely keyframe the object for basic choreography and timing but have the dynamic object “follow” it, like a target. This way you get the benefit of having keyframed motion influencing the dynamics.

Would a sop solver be the right way to go here? Field force? It's been a while since I used dops so any advice or examples would be appreciated. I'm sure there's an elegant solution out there but I'm just not able to think of it.

Thanks very much!

Hi everyone. I stumbled on this thread and was wondering if you've tried using the Area Chop. It's my go-to node for measure distance. Usually I use a trail sop ( like Antoinne did ) but I only trail it for one frame. I measure t he distance between current and previous frame. Then I store that in an attribute that I pull into chops using a geometry chop. Following that with an area chop gives me a cumulative distance traveled between whatever frame range you choose.

hope this helps.
