My guess is that Excalibur tried too hard to save money both with the design
outsourcing and the arm's parts and so lost their investment.

The arm in the picture looks like a limited motion 3 DOF plus a simple gripper.
(I've seen other pictures of the chess pieces and they all have similar tops and
are relatively close in height.)  Twenty years ago this would have been a
novelty (c.f. Novag's Adversary), but today I'd think that most buyers would
want an arm capable of handling a regulation sized board.  That means squares
with a 5 cm (minimum) edge length, not 2 or 3 cm.
