Gazebo SImulation not working properly

i am trying to spawn multiple robots in local machine in ros2 humble but i am getting a weird behaviour where my robots are moving up from one side in gazebo

Hi, welcome to the community!

It is hard to know what could be wrong with your gazebo robot from just a screenshot, but if I had to guess, I would say that the weird behavior you are getting can be because of:

  1. Incorrect gazebo physics: this can be either with the robot or the models the robot is interacting with.
  2. Wheel control: This can be a misconfiguration in whatever you have set as your wheel control, either ROS 2 control or a gazebo differential drive plugin.
  3. Problems in the URDF: maybe an incorrect joint or link definition can cause behavior issues.

We provide the tools to understand Gazebo, ROS 2 and URDF in these courses:
