Hi kannajin,
There are many ways you can use DAQ in a project. If you want to control a robotic arm, you can use the DAQ device analog outputs to control the motor drives that power the motors. You could also use one of our motion control systems. The link below is to the Student Corner on our Developer Zone. There are many more resources for students there. If you give a bit more detail about the requirements of your project and your major, I'd be happy to give you more adivce.
