3D Model combined with physics engine for RN-1

2011-04-12T11:18:57+01:00

You can get the parts in .obj format from the archive in by files area:
http://robosavvy.com/Builders/Fritzoid/RoboSim.zip
You should be able import these into 3DS no problem.

I still have the source files which were created in Blender and can send them to you if you give me an email address (do not it post here). Contact me through private message or email to arrange delivery.

Robonova 3d Model

2010-04-20T21:59:10+01:00

Can someone post a 3Ds Max version of Robonova's model please?

as you can see my model (in my sig or the other thread) is rigged already and its only a matter of limiting the servos to their 180 degrees, which requires me to burn a few calories and move my finger, the mouse and maybe hit a few keyboard buttons and limit their rotational degrees since they are already axis limited...

as for placing the editor inside the engine that may be easier said than done. i have heard that the current robobasic program compiles robobasic to asm inside of itself, but im not positive that this is the case. If that option is added it will be later, but i agree, it is a good idea to exclude the Hitec program totally if possible because i have noticed plenty of small glitches and such...

thanks for your help!

Hi hivemind,

I would like to include your RN-1 models into Marilou Robotics Studio, with physics behaviors (physics + servos) . What do you think about that ? would you agree me to do that ?

Marilou is free during BETA, and will be free for personnal use (non commercial, at home).

Thank you.

Dunno how much of help I could be but I do have quiet collection of things like 3d studio 7, auto cad electrical, auto desk, Alias Motion Builder, cyber motion 3d designer, lightwave, All Bentley Engineering software, and ANSYS CFX v 10.0....some of these are 3D, others complete cad, engineering and physics. if you ask where I got these ...Let's just say Iraq was a wild tour and the markets sold a lot of stuff.

Lots of open-source projects on Sourceforge geared towards physical robot simulation, the most active ones seem to be:
http://sourceforge.net/projects/simbob
http://sourceforge.net/projects/crisis
http://sourceforge.net/projects/simspark
http://sourceforge.net/projects/opensimulator
http://sourceforge.net/projects/roboss

I havent had time to check them all out.
There is also a "physics editor" http://www.physicseditor.com/ Scythe that allows you to build your models physical representation in WYSIWYG way. Unfortunately its save-file format is in binary currently and cannot be written by scripts ( good if you have several similar servos with similar parameters )
There is also very heavyweight Player/Stage project
playerstage.sourceforge.net/
Stage is aimed at 3D physical simulation, its rendering is being ported to popupar opensource Ogre3D c++ graphics engine and its using ODE physics library. No humanoid models built yet, AFAIK

Robonova Simulator

2006-09-05T19:08:53+01:00

Hello everyone, this is my first post at robosavvy

Hivemind, have you made any progress with the robonova simulator?
I have been doing some research on this, and I might help you with it.
Though right now I don't have a robonova (or any other robot), I am
pretty handy with software tools, 3D graphics and C++ / C#.

Looks like the august release of the Microsoft Robotics Studio has better support for advanced joints. (see http://robosavvy.com/modules.php?name=Forums&file=viewtopic&t=524).

It may be worth trying to import the Robonova model into the robotics studio.

Although the robotic studio does not (?currently?) provide services for RN1 - it may not be too difficult to write some code to generate Robo Basic that can be copy & pasted over to the RN1 software.

Except for my own ezphysics, there are many programatic environments to bind Ogre (which is the best 3D programming abstraction library) and Ageia, ODE, Newton, Tokamak. Check out this page. Microsoft have also developed this layer or have built on top of Ageia; need to dig into this.

I've already gone through the Robotics kit from Microsoft and the main problem with this beta is that it has no support for advanced joints (yet) so any other types of robots except for rolling ones are impossible to simulate in it for now.

The services layer of the kit is interesting but it's also a bit wonky now so all and all not much can be done with the Robotics studio for now

Wow, sounds daunting..

But I'd be willing to help with modeling, rigging, or optimization if you need it.
I've also done some work with unreal, but nothing mind blowing..

A sim like this would also make for a great game..

2006-07-05T13:07:38+01:00

I used webots before. its a pain in the ass to use. controls on it suck and there are more settings in it than there are stars in the sky. i wouldnt suggest using it unless you have a few 100 hours of free time to figure it out and make your enviroment + robot (more of a pain). since the walls dont have collision detection, you need to do like 2x or 3x the work to add collision detection (so the robot doesn't walk through the door!!) i can rant on about this program for hours. just drop me a pm and il rant on

(i first posted this on the other thread and now moved it here.. so i may be off the thread flow kind of ..)

Writing a 3D physics-enabled simulator is a very big piece of work. Having done it, here are the parts that are required:

0) The actual physics simulator - collision&inertial objects, joints and collision detection

1) binding layer between physics simulator and 3D meshes including skeletal mesh

2) Editor for interactively placing the physical objects into the skeletal mesh

3) Finally the "intelligence" that applies forces to the robot's joints (otherwise it's just a ragdoll)

0) simulator - this is a suicide missions that can not succeed as a hobby project also because it is in the process of being standardized by Microsoft, Ageia and other big names. If 6degree tensors, LCP solvers and Lagrange multipliers is your forte', join the ODE.org club or see the career opportunities section at continuousphysics.com

1) - Has been done. Binding between the 3D mesh and the simulated physics objects has been done by several game engines. Except for my own ezphysics, there are many programatic environments to bind Ogre (which is the best 3D programming abstraction library) and Ageia, ODE, Newton, Tokamak. Check out this page. Microsoft have also developed this layer or have built on top of Ageia; need to dig into this.

2) I've worked on this editor piece quite a bit with ezphysics. Haven't uploaded the source code, just the exe, cause it's a big hassle to compile but i'll be happy to share this code. I heard that Maya allows you do do something like that with Havok but Havok costs $200k. I'm sure that Ageia have invested in providing such development environment with 3Dstudio/Maya for their own engine and file formats.

3) If you choose to do 1 and 2, I don't think you'll have much energy left for making the control system for a simulated RN1 which is IMHO where all the real fun resides.. so i can highly recommend against doing 1 and 2 if this is a hobby project.

I'll be happy to help build a humaniod robot simulator.

BTW: There's at least one commercial product - http://www.cyberbotics.com/ and one big academic project - http://www.germanteam.org/GT2005.pdf
