Readme

Contains a list of reactive planners specialized in locomotion of legged robots. The reactive planner adapts the step location and timing of the gait based on feedbck from the CoM states and sends the desired swing foot trajectories to an instantanous controller for tracking.

Installation

Standard dependencies

Here all the pip and apt install-able stuff

Download the package

Install treep and colcon .

Build the package

Then follow the instructions below:

# install treep and colcon
pip install -U treep colcon-common-extensions
