The pieces of the Daedalus interlock thanks to metallic rods running into grooves that form a labyrinth inside the puzzle. As pieces move, the paths formed by the grooves change.
Although the rods and grooves can be designed with Burrtools, the software can't solve the puzzle because the solution involves many rotations.
"Daedalus seems to be a classic interlocking 3x3x3 cube, but, on the internal hidden faces, pins inside grooves, can define it, like an internal evolutionary maze. When a piece moves, a part of the maze moves with. Each unit of the cube has edges cut which permit rotations. All the possible moves can be used. One unique solution. Level : 49 (23, 9, 8, 3, 3, 1, 2) rotations required." -Gregory Benedetti
