Nope. The really long ones are Mindstorms. They come in handy for remote control. The shortest one (15) and the long middle (70) are from the space shuttle. The 20.5 come in ZNAP and Mindstorms. I don't know about the shorties being in the expansion (...) (25 years ago, 22-Nov-00, to lugnet.robotics, lugnet.technic)

I believe the 2 middle lengths are from Minstorms RIS. The longer ones are used in the 8480 Space Shuttle and the very short ones came in the Minstorms expansions (ie: Robo Sports and Extreme Creatures) as well as the smaller Z-nap sets.
