02.7 - Conclusions & Future Work
Lessons
Through this project we learned about using MATLAB for kinematic analysis to help aid our design process as well as Solid Works, motor selection, and programming. On the hands-on side, we developed soldering, laser cutting, and 3D printing skills.
Accomplishments
Successfully produced our desired motion profile for oars in tandem.
Developed a boat body for our oar set up
Experimented with flotation devices
Improvement Areas
For future work on this project, we would like to continue exploring the floating aspect of our boat. We would like to explore alternative base designs that are both compact and buoyant to reach the ability to self-propel in water. Additionally, we would like to experiment with different designs for the oar, and how it interfaces with the rest of the boat. Ideally, we would have a better “grip” on the driven end of the oar. Lastly, we would like to adjust the design so that the oar does not roll as it moves in the water, but instead always remains perpendicular to the horizontal motion.
Tips
Don’t be afraid to iterate – our design changed and evolved many times
Start being hands-on early! You will realize parts don’t fit or make sense to operate in real life
When working with gears, vibrations or play can lead to poor meshing due to interference.
Where possible, use spade connectors, Wago/lever nuts, and any other method to securely connect electronics without soldering. This will allow for easier prototyping but also allow for easier replacement/repairs if something breaks.
