Electric Vehicle
Overview
I created this electric vehicle individually for the 2024-25 Science Olympiad "Electric Vehicle" event. My partner helped with testing the vehicle.
At the 2025 UPenn Invitational, I placed 2/72 (behind the Nationals winner!), and at the 2025 Princeton Invitational, I placed 4/57.
At the 2025 Maryland State Championship, I placed 2/28. At the 2025 East Maryland Regional, I placed 1/48.

Assembly & Testing
Integrated test of BLDC motor and MT6701 Rotary Absolute Magnetic Encoder.
Arduino Nano outputs PWM for BLDC ESC, and reads MT6701 through I2C.
First ground test with HDF (hardboard) CNC plates, at its full speed.
Plates were too heavy and ESC was configured suboptimally in BLHeli_32 Suite, hence poor performance.
The electric vehicle mid-rebuild, with redesigned 1.5mm G10 fiberglass CNC plates.
Vehicle had significantly reduced weight, and was significantly faster.
