Hi all,

I am quite new to Houdini so please excuse me if the answer is super simple.

Been trying to learn how to rig a little lately with small industrial robots (3DOF)
FK systems are simple enough to implement however, I want to create a simple 3 bone IK rig with each bone only given a single rotational axis of freedom. i.e. bone1 one can only rotate around x axis, bone2 - y axis, bone3 - z axis to reach a single goal. 
Is this possible? I hope this can lead me down the path to creating "simple" IK rigs for Industrial robots with 6DOF (but I am dreaming here).

I saw Maya already has a plugin for this sorta thing called Mimic, open source and quite elegantly done > https://www.mimicformaya.com/
I was wondering if its possible to build similar functionality within Houdini.

Yes, it's possible ...Have fun ..search on GITHUB and google ..here you have something that peoples Done with Arduino just search :wub:

Hey Librarian,

Thanks for the link! I went through this walk through few days ago, along with almost 5-6 other rigging tutorials too. (Side FX have some great ones that explain a lot of fundamentals quite well through their rigging series of H16.)

However I cannot find the particular outcome or approach I am after. I think I clearly lack the terminology needed to explain my problem.
Simply put, I need bone1 to only move along x, bone2 to move only along y, bone3 along z. As soon as I have an IK system, it simply does not constrain the 'joints' to individual axis unless I use FK. Even with parenting or creating controller nulls in IK i cannot restrict movement to a single axis. I will attach some screenshots/gifs tomorrow to elaborate and explain myself better.
