diff_drive_controller without wheel encoders?
I'm working on a skid steer style robot, and I would like to use the diff_drive_controller to control the drive system (including acceleration limits). The robot uses a fusion of GPS and IMU data to get localization but does not have wheel encoders. I'm new to ROS and ros_control. Is there a way to implement the controller without wheel encoders for the joint state?
Did you ever find an easy solution to this?
