CoppeliaSim forums

Hi, I use Coppeliasim to build the convex hull of 7 dof manipulator, and then I want to export it as urdf and meshes flies, Coppeliasim provide simple xml button, but how can I export each of the meshes by one-click instead of one by one?

Thank you!

I see, Thank you very much!

CoppeliaSim only has an URDF importer. The best you can do is save your scene to CoppeliaSim simple XML format, and work on that file to create the URDF pendant.

Cheers

Very nice simulator, Can I export the URDF from 7 DOF manipulator.ttm ? Or where can I download it, I want to import this URDF with STL model into the Matlab Simscape™ Multibody™ toolbox and compare dynamic algorithm. Thank you for your helpful advice!

--- Oh, I'm so sorry, I didn't notice the Inertia matrix divided by the mass: the inertia matrix or tensor. Values are mass-less in shapeDynamicsProperties page . The physics engines are right because the inertial matrix has divided by the mass, so the left \ddot{\theta}_l = 8.66*e4\times 9.81\times...

hello, yesterday I have test a single rigid body rotating under gravity in the y-axis. because the equation is very simple. I can write \tau = M\ddot{\theta} + mgrcos\theta . So I design a cuboid in V-rep. in the following gif, The left body M is 8.66e-4kgm^2 and m = 4e-5kg , and the right cuboid M ...

There is a difference between collidable and respondable . Cheers Two respondable shapes will always produce a collision reaction unless their respective collision masks don't overlap. Thank you! I have to disable respondable , and see some chaos motion of three-link planar under gravity, this is m...

Hello, are you sure that your adjacent links are not colliding? If they are colliding, they will of course prevent the mechanism to bend and take another configuration than a straight line. In the general dynamics properties , try to enable Display contact points to see if there are collisions. If ...

Hi, I am also a beginner in coppeliasim and I think there may be something wrong with your setting. 1. You may enable the motor of the joint just by dubble clicking the icon . 2. You may set the local respondable mask of the links to 1111000, 00001111, one by one just like this. 3.Once you do the t...

Recently, I test Newton-Euler dynamic algorithms in Matlab. Here is my result about the 3R-planar manipulator moving under gravity. https://5imcs.com/posts/1e752288/testAnimated.gif Time step is 0.05. The mass of each link(cuboid,x = 0.10; y = 0.02; z = 0.02;) is 4.000e-5/kg, In order to check my re...
