Hey, I've been using 25 robots of the same type in a swarm simulation in Gazebo 2.2.3 on ROS Indigo. After about an hour of simulation at least half the robots are fixed in the centre and I cannot move them with the hand tool. They do not respond to their subscribed topics, and actually change shape. In the attached picture ( ) are the normal robots and in the bottom right are about 10 fixed/stuck in the same place. I can't find anything like this online and there are no errors printed on console. I have no idea how to address this and would much appreciate any ideas.

I would like to add that I have seen this happen when a robot flips on it's side. Is it something to do with Physics breaking?

It's probably better to ask this on , and you should definitely include at least which robot model you're using, and which (if any) gazebo plugins you're using to simulate your robot.

That's a good suggestion, will do.
