I recommend you read the user manual section on Creating dynamic simulations

The reason that your URDF import behaves in an unstable manner is because URDF is an exchange fileformat mainly, that can be used to serve several purposes, and that can be badly created/generated. In your case, the file appears to contain only heavy, non-dynamics optimized meshes (e.g. the wheels ...

Hello,

your scene show an immobile robot: positions appear to be holding in a stable fashion. You are probably using the remote API to move the robot around. I also noticed that you are probably using the legacy remote API, which we do not support anymore. Make sure to switch to the ZeroMQ remote ...

You will have to host the file yourself, and post a link to the file. Have also a look at this post related to possible problems with the URDF importer.

Hello,

yes, the origin of images is at the bottom left. Pixels are organized from left to right, and from bottom to top.
From C++, it is faster to do the transformation yourself, with a simple loop. If you want to flip the image vertically, simply do something like (in case of the depth buffer ...

Hello,

you have following matching API functions:

sim.packFloatTable / sim.unpackFloatTable
sim.packDoubleTable / sim.unpackDoubleTable
sim.packUInt8Table / sim.unpackUInt8Table
sim.packUInt16Table / sim.unpackUInt16Table
sim.packUInt32Table / sim.unpackUInt32Table
sim.packInt32Table / sim ...

Hello,

I cannot reproduce this via the interactive headless mode. Can you try following from the terminal:

./coppeliaSim -H

...

> s1=sim.createPrimitiveShape(sim.primitiveshape_cuboid, {1,1,1})
> s2=sim.createPrimitiveShape(sim.primitiveshape_cuboid, {1,1,1})
> sim.checkCollision(s1, s2 ...

If you want to change the timestep with versions prior to V4.9, use:

Code: Select all

sim.setFloatParam(sim.floatparam_simulation_time_step, 0.01)

Cheers

What CoppeliaSim version are you running? What does it print when you type:

Code: Select all

sim.getProperties(sim.handle_scene)

Cheers

coppelia

Hello,

try with sim.setFloatProperty(sim.handle_scene, "timeStep", 0.01)
Just make sure simulation is not yet running.

Cheers
