[HELP] Moving an object in a two-axis way

[Smolt]

Hello,

Firstly, I'm sorry if I posted this in the wrong topic, I'm new to the forum.

Secondly, sorry for my poor english, especially in this kind of topic. I hope you'll manage to understand me !

So my goal is to make a "two axis deplacement system" (the same system as the Etch a sketch uses, look here : http://en.wikipedia.org/wiki/Etch_A_Sketch)

I would use this system to move a camera. It would need to move it 8 times (in order to take 9 images : 3 rows of 3 images).

However it would need to be really precise (theorically each deplacement is 18 millimeters on the x axis and 13.5 millimeters on the y axis. It would of course need to overlap for a better coverage) and strong, because the camera weights 265g and is 113*68*33 millimeters.

I would place the system in a wooden box crafted to the right size and then hold it in a way that the camera is vertical. Most importantly, it would need to move the least possible on the z axis.

Do you know if it is possible to make this kind of system using lego NXT 2.0 , or maybe other Lego technic parts ? If it is possible, do you have any idea on how to make it ?

Anyway, thank you for reading this,

Best regards, Smolt

I don't see any reason you couldn't do it with rack gears and a control center just like the 8094 plotter.

Thanks Blackbird, I dont have this set but I'll try to use it as an inspiration.

There is a YouTube video of a sudoku solver using an NXT.
