Final result
After a long work, many solutions found due to unexpected problems and many hours spent
in the laboratory, we finally managed to complete our project. Indeed, our robot performs
to perfection the specifications that we set at the begining. As you can see on the video,
the robot works as expected in two phases: the update of the time and the writing of time
every minute.
Functional Roboclock
Possible improvements
Although our robot works as expected, we believe that some improvements can be made:
Better tip for writing
The tip was cut on a white board marker. It therefore dries very quickly which is not
practical for extended use. Another writing system or an easy way to recharge the tip can
therefore improve the quality of the robot.
Writing in calligraphy format
Use the motors at the same time to be able to write calligraphy digits instead of the digital
format. However, this improvement requires further programming and a change of certain
components in order to no longer control the motors sequentially.
Provide cooling
Although they were equipped with heat sinks, the two voltage regulators (see here) heat a
lot. Provide a cooling system to prevent damage to the electronics can be beneficial for the
longevity of the robot.
