On week three I started by completing the code for the fog screen machine’s controller. I made a class for serial communication between the Fetch robot and the Arduino board. I tested the code and it worked as expected. I worked on the introduction section of the research paper with my lab partners. We are now going to improve it. Moreover, my lab partner and I are going to 3D print a new case for the controller. The case will be a bit larger and will be better suited for the controller’s components.
