[MMM]

With just one back translation:

The speeder is stopped on a crowded street by several combat-hardened stormtroopers who look over the two robots.

to

スピード違反は、混雑した通りに2台のロボットに目を� �す、いくつかの戦闘硬化ストームトルーパーで停止し� �いる

ro

Speeding, the two robots look through the crowded streets, fighting has stopped in curing some Stormtroopers.

Notice how the actors of the verb "to look" is shifted from the stormtroopers to the robots. Also notice how the noun "speeder" has been changed to a verb and the the adjective "combat-hardened" has become the noun "fighting". The stopped speeder is now "stopped fighting". I don't know where "curing" came from.
