Knex Auto-Turret?

I need help making a knex auto-turret (a turret  that can lock-on to targets and fire at them) with a single cyberknex set because i dont have another $60. Does anyone have any ideas on how to make it lock-on and follow something? That is all i need help with.

well your gonna need a infared targeting system for one pretty easy to build.

well if you dont wanna do that just make it a a trip wire in each direction and a gun in each direction and hook the ropes up to the triggers of the guns
easy enough?
