What model to use

I did a very simple study and I'm not sure what model to use for analysis. This was my setup:

1st Column -- Observations: 1, 2, 3, 4, ..., 30
2nd Column -- X: [30 different values]
3rd Column -- Y: [30 different values]

I have a robot placing an item on a platform. I give it the same command to place it in the same spot 30 times. I measure the X-coordinate and Y-coordinate of where the item is placed after each placement. The X and Y values are independent of one another. I just want to analyze the X and Y locations over the 30 observations. There is no interaction between X and Y.

What do you suggest?

Thanks,
Lisa
