casannis_walking

Trajectory Optimization based on CasADi, implemented for IIT's Centauro robot.

✔️ Offline/online trajectory optimization for quadruped robots and quadruped manipulators carrying heavy payload.
✔️ Implemented using CasADi and its interface to Ipopt solver.
✔️ Implemented in Python, based on ROS.

Dependencies

The repo has been tested on Ubuntu 18.04 and 20.04, using the XbotCore 2 and Cartesian Interface developed within the HHCM lab of IIT. To use the repo you will need:

• centauro_contact_detection
• iit-centauro-ros-pkg
• xbot2_examples
• centauro_cartesio
• cartesio_collision_support (optional)
• yiannis_centauro_pytools (optional)
• hhcm_perception (optional)

Install & Build

casannis_walking is a catkin package. To install it you need to git clone into your workspace:

git clone https://github.com/ADVRHumanoids/casannis_walking.git

Build with catkin_make / catkin build

Run

The repo is not maintained to enable off-the-self deploying, but rather consists a record of the work done for the corresponding publication mentioned below. People interested are encouraged to contact the author.

For offline trajectory optimization try
