Design Testing

**ClICK ON DATES BELOW TO EXPAND**

September 26th

Designing vehicle to specifications was crucial to the design. After all, the entire design project would not be feasible without a vehicle and a roadway. Therefore the vehicle was designed and built with voltage sensors and current sensors on the back window of the vehicle. Also a power switch was installed in order to turn the vehicle on and off without having to undo the bolts to reach the vehicle's internal

circuitry. Top left photo is an internal shot of the vehicle. Top right photo is the top shot of the vehicle, showing switches, voltmeters, and ammeter. The top left ammeter and voltmeter measures the voltage and current drawn from the batteries from the motors while the right (green) voltmeter indicates voltage level for charging. On the bottom is the vehicle charging circuit. It was embedded here, so the audience can see the circuit under charge. To show the indication of charge, the circuit will light up and blink on the battery value it is charging on.

Designing the roadway is the first step in building a track for the vehicle to run laps around, for testing purposes. Above is a photo of the roadway being cut, shaped, and designed. It is catered to the vehicle and is a crucial part of the design. Afterwards, plates were cut, shaped, aligned, and glued to the track. The alignment and gluing of the plates was crucial to the design, because if the plates touch, a 300VAC line short would occur, and injuries could be procured. Afterwards, it was realized that the roadway caught too much traction to the vehicle, causing it to run off course. So a barrier along with parchment paper (to lessen the impact of traction) was designed in order to keep the vehicle on track.

November 15th

There was a redesign upon the roadway circuit due to countless weeks of attempts due to many factors, including parts that just weren't viable, due to being produced from China (low quality parts that failed through many attempts). Time was of the essence, so the redesign was crucial. The left photo is the original design, the center is an improved (hopeful) design that consisted of a function generator and the amplification circuit, while the right is the finalized circuit design.

November 23rd-27th

Testing as a final circuit was a success. Circuit shows charging voltage (right side), as analyzed, variations in the circuit could be seen. This is due to the fact that the system isn't at nominal resonant frequency. This is something that can be improved upon later in future work. Top photo shows charging circuit successfully being lit. The center left video shows the circuit running without WPT initiated. The center right video shows the system running around successfully lapping the roadway utilizing WPT. The bottom left shows the unsuccessful lap around the track. The bottom right shows the successful lap around the track.
