More parts for the Perler Bead robot
On the left, a sorting disc I'm testing. It mounts directly to a micro servo (press-fit onto the spline gear). It has a circular hole that can hold one bead while the robot examines its color, then at the proper time it can shuffle the bead off to one side or the other, to direct it toward the build surface or to a discard pile.
On the right is the one-piece vibrating funnel, with an early prototype of the bead hopper mounted above it.
