You can do this by opening and closing gates (blue and red gates) and leaving turnips to make them stop. In another varation the Prof is sleep-walking and you must get him through the maze.
The idea is that you play the proffesor while ROB puts "gyros" down on button to open doors.V-e-r-y slowwwly. zzzzz! In truth, the game is more fun if you just forget ROB and use your other hand to open the gates yourself. BUT I have to admit, ROB was a cool marketting ploy. Anyone here play STACKUP? Gyromite alone get a C+ from me but ROB gets a D-. A cool collectible, not fun to actually play with! SORRY, R2!!!!
The only purpose it served actually was to give the impression to retailers that it was a toy, that just happened to also play videogames. Once the system established itself and Nintendo had made retailers realize a market for home video games still existed, it quickly disappeared.
gyro C)make gyro spin D) pick up Gyro E) Put gyro down on button
'A"....ZZZZZZZZZzzzzzz..... really by that time most kids would be asleep. Far better to work so that it just gave the IMPRESSION that Rob was "alive" rather then relying on that slow-motion
movement. Press "pause, Rob would blink his eyes, open and close claws...maybe even speak.and the gates would open. Of course, it would still make ROB Extrenuous, but kids would've gotten more "fun" out of it, I'd bet!
