Two-Axis Nerf Turret
In 24 hours my team built a two-axis Nerf turret that spins a full 360 degrees, feeds from a gravity magazine, and rides on a custom thrust bearing. An Arduino and a Raspberry Pi handled the motors and servos. I cycled through several indexer designs for the servo rotation, tightening rigidity and tolerances as we assembled. We placed second out of 40 teams, scoring highest on complexity and completeness.
