Hi @Arkapravo. I have the URDF model ready actually, but the problem is that inertia properties of DarwinOP are much lower than the example in the tutorial, which means that unusual behavior could happen.

2012-06-07 10:20:50 -0500 asked a question Simulating Small Robots in Gazebo

Hi there, I'm Trying to simulate a model of DarwinOp (an small size humanoid robot). Right now I'm writing URDF files for the robot but I noticed that gazebo doesn't like small robots. From URDF tutorial :

When using realtime controllers, inertia elements of zero (or almost zero) like <inertia ixx="0.1" ixy="0" ixz="0" iyy="0.1" iyz="0" izz="0.1"/> can cause the robot model to collapse without warning, and all links will appear with their origins coinciding with the world origin.

I've tested the partial model in gazebo and saw some weird behaviors (e.g robot flying around or collapsing to the origin).

Is there any solution to that?

it just needs administrative permission. Use shell in superadmin mode, type:

sudo bash

it will ask for your password,type your current account password. then type the rosemake command, this will resolve the problem of creating directories.
