 # Statement of Need
 Modern robotics is moving more and more past the traditional robot systems that have hard-coded paths and stiff manipulators. Many use cases require the robots to work in semi-structured environments. These environments impose uncertainties that could cause collisions. Furthermore, many advanced assembly, manufacturing, and household scenarios such as insertions or wiping motions require the robot to excert a controlled force on the environment. Finally, the robot workspace is becoming increasingly shared with human workers to leverage both agents and allow them to complement each other.
