leggedrobotics/xpp

Xpp is a ROS package for the visualization of motion-plans for legged robots. It draws support areas, contact forces and motion trajectories in RVIZ and displays URDFs for specific robots, including a one-legged, a two-legged hopper and HyQ. More example motions can be seen in this video, generated by the library towr.

Install

The recommended way to install is through the ROS binaries:

sudo apt-get install ros-<ros-distro>-xpp

Build from source

In case you don't want to install from the ROS binaries, this package requires Eigen and ROS:

sudo apt-get install ros-<ros-distro>-desktop-full
sudo apt-get install libeigen3-dev

Then you can build the package in your catkin workspace

cd catkin_workspace/src
git clone https://github.com/leggedrobotics/xpp.git
cd ..
catkin_make
source ./devel/setup.bash

Unit Tests

Make sure everything installed correctly by running the unit tests through

catkin_make run_tests

or if you are using catkin tools.

catkin build xpp_vis --no-deps --verbose --catkin-make-args run_tests

Usage

A few examples for different robots are provided in the xpp_examples package, e.g. xpp_examples/src/monoped_pub.cc. For starters, run

roslaunch xpp_examples hyq_bag.launch  // or any other launch file in this package
