Is the usage of the word 'already' in the following sentence correct?

We have used an already calibrated camera fixed on the robot.

  • It's fine but you need to hyphenate. A better choice would be "pre-calibrated"

Yes, this usage is correct. Note that it is conventional to use a hyphen when you are writing a compound adjective (see rule 6.39 given in this answer, which draws from CMoS):

already-calibrated camera

As you are probably aware, this means the same thing as:

We have used a camera that has already been calibrated, fixed on the robot.

Here are some examples from COCA that use "already" to modify an adjective in this way:
