As given by the research question above, one of the central parameters is the question of cost. Since the cost of industrial equipment can be many multiples of the cost of commercially available products, studying alternatives becomes attractive. As given by the research question above, one of the central parameters is the question of cost. Since the cost of industrial equipment can be many multiples of the cost of commercially available products, studying alternatives becomes attractive.
As an example, the cost price of the Intel RealSense L515 used in this project was €380\footnote{Due to Intel announcing that they are discontinuing their LIDAR sensor series, the price of this particular product has risen up to €570 as of January 2022.}, whereas the SICK LM400 used by Fojtik\cite{fojtik2014} can cost upwards of €4000\footnote{This price is an aggregate estimate based on multiple online merchants as of January 2022}. As an example, the cost price of the Intel RealSense L515 used in this project was \euro{380}\footnote{Due to Intel announcing that they are discontinuing their LIDAR sensor series, the price of this particular product has risen up to \euro{570} as of January 2022.}, whereas the SICK LM400 used by Fojtik\cite{fojtik2014} can cost upwards of \euro{4000}\footnote{This price is an aggregate estimate based on multiple online merchants as of January 2022}.

The individual software elements and libraries such as ZeroMQ and Qt were shown to be robust enough to carry out the configuration process.
