Translation:We can't find the robots.
Unfortunately, you can't use -vam as a solitary word. If you're in a situation where you really don't know what the things are, the simplest option is probably to use Dochvam (or Dochmeyvam). In this case, you do know what they are and the best style in Klingon is to go ahead and repeat it:
qoqmey bonejbogh bIHbe' qoqvam'e'
"These robots are not the robots you are searching for."
