OCS2_ROS2 Toolbox

1. Summary

OCS2_ROS2 is developed based on OCS2, it was refactored to be compatible with ROS2 and modern cmake. Below is the current todolist of the project:

• modern cmake
• basic 6 examples in official documents
• WSL2 support
• Fix Quadrotor example's unexpected behavior
• Fix Mobile Manipolator's interactive marker
• perceptive locomotion demo
• tinyxml2 problem in Ubuntu 24.04 ROS2 Jazzy
• raisim demo
• mpc_net demo

The IDE I used is CLion, you can follow the guide to set up the IDE.

2. Installation
