# Software for robot parts interaction modeling

I'm robotic engineer, using OpenSCAD to model robotic components (gears, pulleys, parts, etc). But I need an application to model the physics and interaction of the components (for i.e. how will robot move if I rotate a given gear).

So, is there any software I can use for modelling interactions in Linux? Google SketchUp is good, but I can't use it in Linux.

• Depending on the power of your desktop, you could try to run SketchUp with wine, bochs or maybe vmware. – ott-- Jun 7 '13 at 8:26
• I'm running it in VirtualBox, but It's not always convenient. I need native decision. – Robotex Jun 7 '13 at 11:43
• And when I'm running it in VirtualBox, I need use pirate copy of WindowsXP in it. – Robotex Jun 7 '13 at 11:44

Have you considered modeling the robot in a simulator? V-REP is new and quite good, having lots of examples robots from other famous projects. Gazebo is another popular one that is usually used with ROS (although V-REP also has ROS support). Both run on linux and are open-source.

• V-REP is quite impressive (at least the videos) – Shahbaz Jun 7 '13 at 8:29
• Is it possible to import/export STL in V-REP (for 3d printing) and simulate chain pulleys and gears? – Robotex Jun 7 '13 at 10:40
• I'm not sure about that. I've only briefly used V-REP and am not familiar with all of its features. Sorry! – Robz Jun 10 '13 at 18:59
