There are two Cybotrons. One is an Australian rock band from the 70s and the other is Juan Atkins and Richard Davis from Detroit. While the latter had some rock influence as well, they predominantly did “Detroit electro” driven by drum machines like the 808, prime example being Clear.

Nope. I’m talking about the same Cybotron. Jon-5 was an early member and he was a guitar player. Eventually he quit since the direction changed. But there's still some guitars in some tracks in the Enter album. And Juan Atkins later left because Richard Davis wanted to focus on rock again.

Atkins’ contributions to techno go well beyond Cybotron.

When Atkins left the group, he started recording solo under the aliases Model 500 and (later) Infiniti. The early Model 500 releases like “No UFOs”, in addition to being absolute classics, demonstrate the progression from electro to what we would now call Detroit techno. He also collaborated with many of the Berlin techno pioneers in the 90s, forming a key link between the two cities.

Not to mention that Atkins mentored May, Saunderson, and many of the other techno originators.

(ps. Cybotron is not really techno, IMO. It is better categorized as electro with a few prog-rock and post-punk flourishes, a sort of proto-techno. But pointing this out makes you kind of a pedantic bore, so most are happy to go along with calling Cybotron techno.)
