For some reasons after I start the simulation, the joint start to separate from each other, is there any way I can solve it?

Re: How can I define a soft material or liquid environment?
I wonder can I define a soft object? Since the current material I use for the feet of my robot doesn't look good. How could I define a material that could be simualte as flesh? Can I define "after enter the boundary slow it down" ? Not CoM enter certain height, but object enter the surface...

Re: How can I define a soft material or liquid environment?
I just want to simulate walking in a pond filled with thick liquid, is it possible to do so?

Re: Contrain motion to certain DOF
I wonder does the anchor means floor?
like the "resizableFloor when we build the model?
Also, how can you define a spherical joint between robot and floor while that robot could still move freely? I tried and it looks like there is a fix radius between robot and the joint.

How can I define a soft material or liquid environment?
Hello I want to simulate a biped human model walking in V-REP. I want to simulate the ground reaction force, but don't want to dealing with the balancing problem. Thus, I wonder is there any way I can define a soft material, that I can hang my model in the air, while the feet can touch that material...

Change the frame of Solidwork imported shape?
I am importing the solidwork model I draw into v-rep, however, the coordinate system it gave didn't satisfy me( I want it parrallel to world frame at the beginning), is there anyway I can change that? Or just put a dummy at the center of mass point but don't rotate it, and attached that dummy to the...

Re: What the axis in friction coeff mean?
now I am totally lost. First, I always thought axis of orientation is "3 axis", i.e., the x,y,z axis of the new frame in reference frame, which is the column vectors of orientation matrix. So here we only have one vector for that really confused me. Also, as far as I know, friction force i...

Re: What the axis in friction coeff mean?
Hello, With a surface, you have 2 friction directions that you could handle separately. E.g. you could say that in one direction, the friction is 1, and in the direction perpendicular to the first direction, the friction is 0. This would allow you to mimic a surface structure that lets objects slid...

What the axis in friction coeff mean?
I am currently using the vortex dynamic engine to do simulation. I am confused of the "axis orientation" in the setting for material property. I wonder why it is defaultly define as [0 0 1] (i.e., z axis), does that represent the direction of normal force? Or the direction of friction forc...

Re: Joint disassemble after changing Dynamics engine
I think I solve the problem, it is probably because the ratio between mass and inertia is too large for these dynamic engines.
