+The main function in \file{mean\_correction.cc} is mostly the same as in
+\file{main.cc}, except that it does not use a \class{ControlledMotion}
+instance but a \class{CorrectedMeanMotion} instance to control the Roomba. The
+profile that \class{CorrectedMeanMotion} uses is determined by the floor type
+given on the command line.

+\subsection{Implementation for Experiment~3: Application
+\prog{soft\_start\_test}}
+As the implementation for Experiment~2, the application \prog{soft\_start\_test}
+which is built from the file \file{soft\_start.cc} has the same basic layout as
+\file{main.cc} from Experiment~1. As previously, it defines a custom movement in
+the class \class{SoftStartMotion} (file \file{soft\_start\_motion.h}), which
+is also compatible with the interface defined by \class{ControlledMotion}. This
+class causes the Roomba to constantly accelerate at the start of the movement,
+and also constantly decelerate at the end of its movement, until the target
+distance or angle is reached.
+
+Internally, the class defines a time interval for the duration of the start and
+stop processes, and breaks down the process into multiple acceleration steps
+which each increase the velocity by a constant value, so for sufficient steps,
+the acceleration remains nearly constant. Therefore, a timer is used, which
+increases resp. decreases the velocity over time (depending if starting or
+stopping), until the target velocity or zero is reached, and sends \cmd{Drive}
+commands to the Roomba over the \ac{ROI}. The methods \fnfont{move\_distance}
+and \fnfont{turn\_to} on the other hand calculate the distance at which
+the deceleration process begins, and fire the initial timer to increase the
+velocity.
