Robot Bowl was available in two different dedicated cabinets, an upright and a cocktail, both of them used the same internal hardware.
* The Robot Bowl upright was of the common 1970s 'short cabinet' design, as the machine had no marquee and was only as tall as the monitor. The cabinet itself was covered in dark woodgrain laminate (very popular back then), and all decorative touches were on the large monitor bezel, which depicted a cartoon scene of a gray robot bowling. The robot looks a lot like the Tin Woodsman from 'The Wizard of Oz', except for the top of his head, and the fact that he is plugged in with an extension cord. He is labeled 'XXIDY MFG.' on his back. Some machines also had a decorative 'ball return' on the front at the very bottom of the cabinet.
* The Robot Bowl cocktail was a square box with a perfectly round top, the player controls were on either side of the monitor (and you actually had to look at the game sideways to play). This machine had no decoration of any kind.
