Robot falls over

[griz1112]

When I run gundam_rx78_gazebo gundam_rx78_world.launch the robot falls over on its back. Don't see any errors or nodes not starting so stumped as to what is going on.

Could you give us more detailed information? The robot falls over just after you started a simulator? Or after a few seconds? Did you use kinetic vs melodic? From source and binary? if binary do you use default repository or shadow-fixed (or ros-testing)?
I launched the gundam_rx78_world.launch today and the robot falls or we can say crashes down just after simulation starts, on both source and shadow-fixed binary on Melodic, but sudo apt-get dist-upgrade solves. so there might be some wrong package that has been installed.

It looks like the bottom joints compress then it starts falling backwards. I’m using melodic. Looks like it tries to right itself then flips high in the air. I can make a video if you like. Dan

please make sure that you dist-upgrade the system? and added the video you can also add the output of `curl -sL https://goo.gl/Dj5BCp | bash` so that we can check the installed software versions.

Para mi funciona cambiando en el package gundam_rx78_gazebo el archivo \launch\gundam_rx78_walk.launch en la línea 16 por -z 0.29 -P 0.0, pero podrían probar cambiando el 0.29 por otros valores, ya que en otros casos varia, y en el mismo package el archivo launch\empty_world.xml lo conmentamos toda la linia 22 <!-- <node name="start_simulator" pkg="gundam_rx78_gazebo" type="start_simulator.py" unless="$(arg paused)" /> -->
Luego lanzamos el robot
roslaunch gundam_rx78_gazebo gundam_rx78_walk.launch

Para el caso de gundam_rx78_world.launch deberia funcionar de la misma manera

I have the same issue here, I launch gundam_rx78_world.launch and the robot spawn leaning backward, just like this, i tried changing the urdf of the robot on multiple positions but it does not work. I'm using ROS Noetic on Ubuntu 20.04.
