Build

Clone the repository

Prepare workspace & install dependencies (So far only tested with UR robot arm)

mkdir -p ~/robossembler_ws/src && cd ~/robossembler_ws/src
git clone https://gitlab.com/robosphere/robossembler-ros2
vcs import . < robossembler-ros2/repos/sim.rbs.repos
cd ..
rosdep install -y -r -q --from-paths src --ignore-src --rosdistro humble
colcon build --cmake-args -DCMAKE_BUILD_TYPE=Release --symlink-install

Additionally, if you want to use Cartesian controllers, such as stiffness or others, you need to execute the following:

# in directory robossembler_ws/src
vcs import . < robossembler-ros2/repos/cartesian_controllers.repos

This will also install ros2_control and gz_ros2_control as packages, so it is recommended to delete global packages if they have been installed.

Set Gazebo enviroment variables

Replace [WS_FOLDER] with your workspace folder

echo "export IGN_GAZEBO_RESOURCE_PATH=${IGN_GAZEBO_RESOURCE_PATH}:~/[WS_FOLDER]/install/rbs_simulation/share/rbs_simulation/" >> ~/.bashrc
# or if you have alredy built the workspace
echo "export IGN_GAZEBO_RESOURCE_PATH=${IGN_GAZEBO_RESOURCE_PATH}:~/$(ros2 pkg prefix rbs_simulation)/share/rbs_simulation/" >> ~/.bashrc

Examples

Activate current ROS2 enviroment:

. install/setup.bash
