1992 was tethered; I'm not sure about 1993. 1994 was wireless. I think the control system was from Motorola then, so I'd guess it was probably the same system from 1993 or 1994 until 1998. In 1994 you had only 6 control channels, each of which was Forward/Stop/Reverse -- no speed controllers, no sensors, no programming.

I'd certainly agree with that. The entire 1992 game manual was only 10 pages long!

Size and weight went up very quickly at the beginning, but have been more-or-less the same for quite a while

year / size / weight
1992 / 38cm x 50cm x 34cm / 11 kg
1994 / cylinder 38in high x 36 in diameter / 65 lbs
2000 / 30in x 36in x 60in / 130 lbs

I can't verify other years, but I think 1993 was somewhere between the 1992 and 1994 sizes, and I think the current size has been around since 1998 or 1999. (I'm approximating 30x36 and 28x38, and 130 w/ battery and 120 + battery as the same.)
