New NXT X-Y Plotter ‘Draws’ Attention

without comments

The NXT X-Y axis plotter showcasing some simple shapes it drew.

When you think of a printer, what images come to mind? Generally, printers are considered necessary but frustrating (Office Space, anyone?) pieces of office equipment and like most other cubicle furnishings they are usually pretty boring.

Not so much anymore.

McNamara has yet again created something functional yet stylish, this time by turning an NXT and some Mindstorm parts into a surprisingly accurate X-Y axis plotter. Quite possibly the coolest thing about the plotter, though, is that (taken from McNamara’s blog) “An X–Y plotter is a plotter that operates in two axes of motion (“X” and “Y”)… The term was used to differentiate it from standard plotters which had control only of the “y” axis, the “x” axis being continuously fed to provide a plot of some variable with time.” This mean that the pen itself moves in both the X and Y directions (technically it moves in all 3 axis of motion, but the Z axis doesn’t come into play on this plotter, except to move the pen on and off the dry-erase board) and that the table stays in a static position; very cool.

Don’t take our word for it though; check it out on McNamara’s blog (complete with pictures, video, code, and building instructions)!
