four wheel steering controller

Hello All,

I am looking at the code in the four_wheel_steering_controller package found in the ros-controllers repository: https://github.com/ros-controls/ros_c...

I am wondering if someone can provide sources or explanations for the derivations of the four wheel drive/steering kinematics implemented in this controller. I can't for the life of me find anything on the web and starring at nested tan functions is difficult to visualize..

Thank you all,

Probably to late,

but I just found Linorobot as I was looking to switch from diff drive controller to 4wd.

Linorobot is a suite of Open Source ROS compatible robots that aims to provide students, developers, and researchers a low-cost platform in creating new exciting applications on top of ROS.

Supports multiple types of robot base:
