ICRA 2023 quadruped competition simulation map

  • Version 2.0.1

Package summary

A repository for ICRA2023 Quadruped Robot Challenges. Used for build, test, and deployment.


Overview

  • A repository for ICRA2023 Quadruped Robot Challenges. Used for build, test, and deployment.
  • This repository provides a ROS URDF package for simulation map.
  • You can download and check map overview from here.
  • You can find information about the challenge on the notion page

Installation methods

ROS must be installed.

1. ROS

Tested on ros-melodic and ros-noetic versions. ROS Install

2. Dependencies

sudo apt-get install ros-$ROS_DISTRO-xacro ros-$ROS_DISTRO-urdf ros-$ROS_DISTRO-urdf-tutorial
sudo apt-get install ros-$ROS_DISTRO-joint-state-publisher

3. Gazebo

sudo apt-get install ros-$ROS_DISTRO-gazebo-ros-pkgs ros-$ROS_DISTRO-gazebo-ros-control

4. Tutorial

clone the URDF package

cd $ROS_WORKSPACE
mkdir src
cd src
git clone https://github.com/rise-lab-skku/ICRA2023_Quadruped_Competition

build & install

cd ..
catkin_make

visualization with Rviz

roslaunch ICRA2023_Quadruped_Competition rviz.launch 

import urdf environment from gazebo

roslaunch ICRA2023_Quadruped_Competition gazebo_world.launch 

You can use the launch argument to select and load only maps of that difficulty level.

roslaunch ICRA2023_Quadruped_Competition gazebo_world.launch course:=hard # or easy

In this version, we only provide a method to import the urdf environment from gazebo simulation. If you want to use another simulator, import urdf/map.urdf directly

Simulation Speed in Gazebo about ICRA2023 Quadruped Robot Challenges

Dear Jeongmin:
Hi!
I try to use your the ​ICRA2023 Quadruped Robot Challenges envirment​ in Gazebo but when my robot touch down in the map terrain, it suddenly get slowing down and the robot can barely move​.
The real_time_factor is almost 0.05, but once the robot leave the surface it can speed up to 1.

P.S. the physics config used in my world is

<physics name='default_physics' default='0' type='ode'>
<max_step_size>0.001</max_step_size>
<real_time_factor>1</real_time_factor>
<real_time_update_rate>1000</real_time_update_rate>
</physics>

and my system is ubuntu 20.04 and use ROS noetic.

Am I in a correct configuration?
And is there any way to speed up my simlation?

Thanks a lot!
