Rubberband car
Competition: won 2nd
Given 3 iterations to design and 3D printed a compact rubber band-powered car. 2nd CAD project, using Solid Works. Focused on optimizing the powertrain for maximum distance and speed. Iterated on designs to overcome friction and balance weight distribution.
In association with
Design for tolerance
Given a Lego axel dimension in 2D drawing, 3D prints parts that will fit this axel.
Coupling Bands
To increase the potential energy stored, we coupled the bands the increase the “length of the spring”.
Iteration 1
As this project isn’t graded, being creative its own winner.
Start with a basic shape, then brainstorm mechanism that could work:
2 chassis design. As the car drives, the chassis would separate to generate energy.
Iteration 2
Improved shape. However, it didn’t expand as the energy within rubber band was too great, pulling the car back together.
Iteration 3
Toying around in solid works to make the most impressive shape.
Removal of the decoupling system.
Came 2nd in the distance competition, but first in the look department.
