I know it's a small detail, but I was just curious if anyone knew what the "eyes", or domes were on both sides of REX's head? You know, the two cylinders with glass balls inside of them? (I know, I am terrible at describing, but I'm sure you get my meaning)

Also, what are the 3 cylinders on each side of REX's legs? There right beside the rocket pods, on the knees.

I'm sorry, I was just curious if they were purely cosmetic, or had a purpose.
