Question by Jufranz · Sep 10, 2011 at 01:17 AM · physicsmodelinghardware

Robotic Arm, how to create

Hey guys,

I'm new to unity so i'm not shure if i'm doing it right.

I have the SensAble Phantom Omi device and I wanted to model its arm. I've tried do create 3 cylinders fixed by 2 joints then when move one parts the others would move along but restricted by the joints. Of course no succes =/

What is the correct method?

Tks =D

I want to say a couple things. To make meshes/objects for games I almost always use Blender. What you do is you model and/or create what you want in Blender (since Unity isn't really a modelling program), then you export it as an Autodesk FBX file, and bring it into Unity. I would suggest downloading Blender (http://www.blender.org/) and then looking up some tutorials for Blender 2.5 on Youtube. Of course there are other 3d modelling programs such as Maya, Autodesk (which are both software you have to buy), and some various ones. I would suggest Blender to a beginner because honestly it doesn't make that big of a deal what you use (in the should I use paid modelling software or free software question) except for a couple little things.

By the way, welcome to Unity! It's a great program.

I just wanna add one tiny correction. That program you're referring to is called 3D Studio $$anonymous$$AX, Autodesk is the company which made that AND $$anonymous$$aya (which, to me, is quite funny because I don't really see the point of one company making two completely separate 3D modelling software titles).

If I model it on blender and export it to the FBX file will it preserve the axis created? If I can create the axis of course.

Or the best way would be create all the pieces separatedly and then create the joints on unity?

Hmm weird i've poseted an answer but it's not here... my bad.

So, i don't need anything fancy. Should I create the parts on blender, add the axis to them and the export or should I create the pieces export them one by one and then add the joints on unity? Does the FBX sabes the joint and axis with it?

Tks =D

Yeah I'm thinking they will, considering that everything I've done in Blender that I exported comes into Unity exports perfectly. Oh yeah and I know you're new so it really doesn't matter, but on Unity Answers generally if you have a question you add a comment to the person who answered your question. But it doesn't matter this time. :D
