Re: UR5 IK Path Generation Fails

Hello, the problem with the second robot is that it starts in a singular configuration, i.e. it loses several DoFs when stretched like that and Ik can't work. The solution: simply slightly move away from that configuration, so that you regain all 6 DoFs again. You can do this by e.g. setting an init...

Please post your scene file, that would be easier to understand what you are talking about.

Re: Easy to crash when using " Create dummies on mesh surface"

Indeed, we are able to reproduce this on some Windows machines... strangely it appears to be related to rendering.

A temporary workaround would be to click (in order to generate a dummy) and shift the mouse a few pixels before releasing the mouse button.

Re: Easy to crash when using " Create dummies on mesh surface"

Thank you for the info. Can you help me identify when the crash happens exactly (the Windows stack trace is not usable)? There are 2 components that play together: addOns/Point sampler service.lua and addOns/Create dummies on mesh surface.lua . Please try to add some printToConsole commands here and...

Re: Easy to crash when using " Create dummies on mesh surface"

Hello,

it seems that the IGL plugin fails to load. Can you confirm again if you type following?

Code: Select all

simIGL = require('simIGL')
Does above instruction alone crash CoppeliaSim?

We will release CoppeliaSim V4.8 in the next few minutes, please try also with that version.

Cheers

Re: Transfer a locomotion policy of a quadruped robot from isaacsim

Hello, URDF portability across applications can be quite challenging. The URDF and your model are extremely heavy and not optimized. Also, the joint control mode should be set to force/torque in your case and many parameters adjusted, such as the armature parameter of the joints (MuJoCo). If running...

Re: How to set a higher FPS before simulation?

Hello, yes, when simulation is running, it runs as fast as possible. When simulation is stopped (and the mouse button not down), the FPS are limited to 8 by default, which is also the number of sysCall_nonSimulation callback calls. Starting with V4.8, to be out in a few hours, you can modify this wi...

Re: I cant make simIK work in python

The best is really to upgrade to V4.8, since most things are inter-connected. V4.8 should be out within a few hours.

Re: How to reduce the time of ‘Simulation scripts called’.

Try to identify what takes most simulation time. If it is e.g. vision, then you can try to acquire images less frequently by setting the vision sensors to explicit handling then explicitly calling sim.handleVisionSensor upon then when a new image is required, which might be much less frequent than t...
