1.7 - Conclusion and Future Work

Conclusion

The window washer was just an idea at first, but we made our idea real by working through many different prototypes and iterations. It became apparent throughout our design and manufacturing process that simplicity often outshines complexity due to its ability to adapt to changing designs. Ultimately, our system achieved the goal it was designed for: to wash windows. The window washer was able to execute the process of moving down and washing the window when affixed to a surface.

Future Work

The window washer could be further improved by supplying the correct motor voltage to allow the apparatus to move both upward and downward rather than only downward. If two 9V batteries were used, the input voltage could be regulated to 12V via the Arduino to address this issue.

To continue developing the project, the overall size of the system would need to be increased so that window wipers matching the width of industry-standard windows could be attached. Another improvement would be designing for two degrees of freedom to allow for lateral motion, likely through a carriage system mounted at the top of the window to support the apparatus.

Future students taking Robot Mechanism Design should carefully consider the practical applications of the components they choose for their projects. It is important to check device specifications and ensure the required operating parameters are achievable. An issue to avoid is overcomplicating a design for a problem that can be solved with a much simpler solution. Always think objectively about the primary goal you are trying to achieve.
