In the video, I was testing the DC motors and their stability. The flywheels were not a snug fit on the motors, causing them to slip slightly and misalign while spinning. In later iterations, I 3D-printed multiple flywheels to find the best fit with minimal slippage. The motors were also slightly misaligned due to differences in how they were taped and the vibrations from high-speed movement. While the setup was relatively stable, further adjustments were needed to ensure proper alignment of both the motors and flywheels so they remained centered on the ping pong ball.
