R.O.B. (Robotic Operating Buddy) was an accessory for the Nintendo Entertainment System (NES). Receiving commands via the TV screen flashing signals through its eyes, R.O.B. supported only two games which involved R.O.B. moving around plastic discs.
Released in 1985, R.O.B. had a short product lifespan with support for only two games, Gyromite and Stack-Up (the “Robot Series”). R.O.B. was released in the US with the intention of portraying the NES as something novel – a “robot game system” – in order to differentiate it from the failed “video game systems” of the 1983 video game crash. It was available in a Deluxe Set, a configuration for the console that included, among other things, R.O.B. and Gyromite.
R.O.B. receives commands via optical flashes (there are six different types) in the screen. Just like the NES Zapper, R.O.B. only functions correctly when coupled with a CRT type television. A puzzle-platformer, Gyromite involves player collecting dynamite before the time runs out, with several red and blue pillars blocking his way. Player commands R.O.B. to place gyros on red and blue buttons (pushing the A or B button on the second NES controller), thus moving the pillar of the corresponding color. Stack-Up was sold with its own plastic blocks, and includes a series of mini games for R.O.B.
