Rigging Robot Arm And Cmotion.

16 posts in this topic

Hello, I going to rig my first robot-arm, never did it before, I really want to do it well.

I going to model robot, I already watched few tutorials how to rig, but I still now sure how to animate robot then.

Let's say I've modeled model , like this (coloured bug) and I have it done and ready to animate.

What should I do?

In my project my robot doesn't walk somewhere, he is going to just stay on one place and stomp, maybe little bit move, but not so far.

I assume Cmotion - is the modul to make Cycle motion to somewhere, yeah? but is it good for stomps? My robot just doing very hard slow movements on almost one place (it going to be just 4 sec video where he's appears and doing laser scan).

Please give me advice, maybe some steps.

DO you know some tutorials on youtube for robot arms?

Thank you.

What should I do first?

Let's say I have modeled robot, just a model.

How should I start?

Should I start using Cmotion or I have to rig robot first?

You have to rig the robot first. Cmotion is advanced expression and it basically provides one with multitude of motion on various axis and much more. After you rig the robot, either manually or with character tool then you can apply Cmotion to the legs. This means you will have to create an action in Cmotion (probably Lift on Y) for each leg controller, or to their parent (hub) which will drive the steps and that is easy if you use character tool since it has "add walk" button which does it for you.

If you are new to Cmotion and your rig will be built manually, that might be a bit more work, but use the same logic you can find in good old vibrate tag for Cmotion too, since the principle is the same :)

The difference is that Cmotion is far more powerful and offers a plethora of options....

You can also take a look at my vol.5 which goes really deep with Cmotion among other things ;)

Cheers

Hello, HSrdelic

I have this model from internet.

I was thinking to use Joint Tool and make a custom joints, but then I've realized I don't know how to connect these joints together to get complete rig with entire body, not just a leg.

So I'm using "Character - Character" and there Advanced Biped, because I don't have robot-template there :)

What do you think is this a good idea to use Character Tool for that?

I've looked in internet and everywhere only characters, but nowhere is Mech or any kind of robots. Dont know why, maybe because Character tool made only for bio characters not for hard-sufrace models?

mechs are very varied in terms of parts. it's why there's no template for them.

you'll have to first figure out how each part moves in relation to everything else before you can even start setting up your rig.

Hello HSrdelic,

I've been watching tutorials about rigging, I've tried to use Character Tool - but it didn't work, because there is no option to change count-bones.

I've used Joints, I've made very basic rig, please take a look to screenshots.

What do you think is it a good way to use Joints?

I just parenting part of my arms to joints.

And my biggest question - how should I make toe for leg?

Please look to screenshot where robot bending his toes. I want to make the same.

For mechanical rigs you don't really need joints since (usually)nothing deforms. Placing axis of objects and nulls in logical places, coupled with parenting, hierarchy structure and constrains can do the job :)

I already did job with Joints, looking pretty good on one leg and now I have to do the same with another leg, I don't know how to make it.

Is there any way to make it quicker? Mirror tool or something?

And after all I want to make it to Cmotion to animate.

As long as the mesh is symmetrical I would delete the weighting and mirror it with the mirror tool. Maybe post a scene file of a leg and we can help you out and give you pointers.... The Cmotion stuff will come last and work off of your CONtrollers....

I did rigging of both legs and now I working with Cmotion.

My robot doing only vertical stomps, I need to make him walk like a hard heavy robot.

Let's say he has to walk only few meters, just like BAMM BAMM BAMM and then stop!

Please here is a link to my scene:
