With this set of four 3D-printed extras, you can use Fable to teach highly realistic robotics:
Pick & Place Robot: Program Fable to pick up an item at one location and deliver it at another, e.g. a table tennis ball picked up by the fork and delivered with precision on the stand.
Maze Robot: Program Fable to tilt and turn a small ball through the maze.
Feeding Robot: Program Fable to pick up food with the spoon.
