Design (Last Tested April 11th, 2018)
The most significant feature of the design is the alternative propulsion system that was previously researched and developed. The propulsion system is comprised of multiple features characteristic of the direct drive system in modern vehicles (“Direct Drive”). One motor is placed directly by the front wheel, making contact through the use of a 3D-printed sphere adhered to it with superglue. Electrical tape is placed both onto the wheel itself as well as the sphere to ensure sufficient contact and friction was achieved while the vehicle was performing. The stability of the motor-wheel system is further strengthened through the use of a rubber band around the L-shaped arm and motor carriage. The trapezoidal wings initially apart of the design were chosen to be removed due to their deterrence of optimal performance.
The updated features allowed for multiple outcomes. First, there was extremely high energy efficiency, having only about one-third of the energy shown with the original propeller propulsion system being used. Second, any coasting effects were eliminated, allowing for exact traveling and stopping motions. Third, the results were much more consistent due to there being less friction present. And finally, the thinner design allowed for better aerodynamics.
