 # Graceful Motion Controller
-The graceful motion controller implements a controller based on the works of Jong Jin Park in "Graceful Navigation for Mobile Robots in Dynamic and Uncertain Environments". (2016). In this implementation, a `motion_target` is set at a distance away from the robot that is exponentially stable to generate a smooth trajectory for the robot to follow.
