7. Conclusions and Future Work - SV

In conclusion, my 6-bar mechanism performed as expected. The model mimics the PMKS simulation to a high degree of accuracy. The PMKS operates at a full 360 rotation of the input angle, and I was able to achieve a majority of that. It took me a bit longer than expected to manufacture and create the model due to my inexperience with laser cutters and nuts/bolts. In the future, I would be able to manufacture a mechanism like this far more efficiently. 

I encountered several problems during the construction of the mechanism, many of which could be fixed in the future with better planning. Using nuts as spacers come with the disadvantage that with constant motion, the nuts begin to rotate around the threads, leading to loose pin joints. In the future, I would design better spacers, perhaps laser-cutted out of acrylic or wood. In addition, I would also use an arduino with servo motor so that I can operate the mechanism without any manual input. Due to the tight tolerances on my model, there are high levels of friction which did not allow for smooth movement across the sliders.
