mocap4ros2_vicon

This project provides support for ROS2 integration with Vicon cameras (MOCAP systems based on vision) as part of the project MOCAP4ROS2.

Installation

Dependencies:

Vicon drivers for ROS2 are based on Vicon DataStream SDK 1.11.0. When compiling the mocap4r2_vicon_driver, SDK is downloaded and installed, requiring packages wget and p7zip-full for this. Also, our package depends on other two repositories from MOCAP4ROS2 Project:

• mocap4r2_msgs
• mocap4r2_control

A rosinstall file is provided to automatically manage them.

Installation steps:

The following commands cover all the necessary steps to install DataStream SDK, dependencies and Vicon driver:

## dependencies
sudo apt-get install wget git p7zip-full 

## create workspace
mkdir -p ~/mocap4r2_ws/src
cd ~/mocap4r2_ws/src

## clone vicon repository
git clone https://github.com/MOCAP4ROS2-Project/mocap4ros2_vicon.git -b master
## clone necessary mocap repositories
cp mocap4ros2_vicon/mocap4ros2.rosinstall .rosinstall
wstool update

## manage ros2 dependencies for our workspace
# rosdep init may not be needed
sudo rosdep init
rosdep update
rosdep install --from-paths . --ignore-packages-from-source --rosdistro humble -y

## build all
cd ~/mocap4r2_ws/
colcon build --symlink-install --packages-up-to mocap4r2_vicon_driver

Configuration

Check config/mocap4r2_vicon_driver_params.yaml for the available parameters. Note that host_name should be the IP address and port of the machine running VICON tracker.

Launching

After sourcing the workspace, the Vicon driver can be started using the provided launcher:

ros2 launch mocap4r2_vicon_driver mocap4r2_vicon_driver_launch.py

Remember that the vicon driver is a lifecycle node, so it needs to be signaled to start:

ros2 lifecycle set /mocap4r2_vicon_driver_node activate
