Overflow is a primarily custom robot for this year's SkyStone game, consisting of an Actobotics holonomic drivetrain, a spring-loaded intake, and a ball bearing linear slide system, built using various 3D printed and laser cut materials. The intake springs open at the beginning of the game for an extra 3 inches of reach outside the 18x18x18 sizing constraint, and the springs allow the intake arms to adapt to nearly all possible Stone orientations. Our lift then takes over with the Zero-Torque Linkage system, which is parametrically designed to never backdrive. The nearly weightless Vertical 4 Bar allows Overflow to stack 11 stones high.
