I have built the mobile robot from the mobile robot tutorial listed on the Gazebo web site http://www.gazebosim.org/tutorials?tu...

However, the robot does not move.

I am running Gazebo version 11 on Ubuntu 18.04

Here are the joint properties: image description

Did you check that simulation is not paused?

Yes, it is not paused. The sim time is increasing.

Are you in selection mode? (arrow up top) The manipulation modes may prevent the model from moving. Also, if you run with --verbose do you see any errors printed?

Hi, Yes, I am in selection mode. I also ran with --verbose and did not see any errors

Did you try higher forces? Also, does the vehicle move if you right-click -> apply force?

Make sure that your joints are set properly

The vehicle does not move if I right click->apply forces.

How should the joints be set? My files are identical to the ones from the tutorial.

Very strange. Does anything else work on the simulation? Can you drag the model up and it falls due to gravity? Do the simple shapes respond to gravity?

It now works with right click->apply forces if i use large numbers such as 300 Nm however is doesn't work if I use the left panel and apply the torques to the joints as specified in the tutorial.
