Hello @gyselid ,

I don’t see the robot in the simulation window, so that could definitely cause some issues. Try restarting the simulation and make sure that the robot is spawned before trying to run any other commands to control it. Let me know if you are still having issues after this.

Best,

Hello @gyselid ,

You should see the robot in the simulation, like this:

 ![Captura de pantalla 2025-11-05 a las 17.37.33](https://get-help.theconstruct.ai/uploads/default/original/2X/7/76d5e06328fbb6ca4d161720333629a9afef7d9a.jpeg)

If you don’t see the robot, then you won’t be able to launch Moveit. If the robot does not appear in the simulation, click on the Restart button at the top of the Simulation window, here:

 ![Captura de pantalla 2025-11-05 a las 17.40.05](https://get-help.theconstruct.ai/uploads/default/original/2X/c/c9d63c5a2452f1476f1366a618224a0d62c086aa.jpeg)

This should make the robot spawn if it failed the first time.

Best,

Now the robot is there, but I still get the same error.

Great! So if it’s still failing with the simulation running, then it means there’s something wrong with your Moveit configuration package. You can send me your package to aezquerro@theconstruct.ai, and I’ll give it a look to see what’s wrong.
