Just have look at the other sensor and give me reply if they can be used with the FRC robots

As Jason said, pretty much anything can be made to work, but the LEGO NXT Ultrasonic sensor works off of I2C communications, as opposed to something simple like an analog output. So getting the LEGO NXT sensor to work on the IFI RC is going to be extremely difficult compared to the maxbotix. I2C is a whole communication protocol that you'd have to implement yourself on the RC using digital IOs. Think of it as akin to reading a speedometer by pressing a button to light up and individual segment/bar on a 7-segment LCD, versus looking at where the needle's pointing. You might get more accuracy if you do it the first way fast enough, but it'd be pretty painstaking.
