FRC Day 12 & 13 Build Blog
Day 12 and Day 13: Programming and Prototypes Prototyping A lot of things got done with prototyping today. We were able to assess the merits of topspin vs backspin, and we determined that the backspin shooter was better for the following reasons after extensive testing: Balls do not jump out of the…

FRC Day 7 Build Blog
Day 7: Shooter and Prototypes Prototyping Double Wheel Flywheel Today, we added wooden bars to prevent the ball from moving back and forth, as well as moving the polycord to the outside to limit disturbance. We then tested it, and it was very consistent and accurate. After fine tuning for a time…
