Lego NXT Mindstorms- Print-O-Bot

[stephthao]

that is not cool man because some body made a printer with no wires beat that.

[222Doc]

@stephthao what are you talking about? There is no NXT that is wireless.

[01tommrazek]

@222Doc He thinks he can compare this to a real printer... Great job!

[222Doc]

@bababoy10 each shape is a set of motor moves in a loop. since in this contest they only had a rule that it must print three differant shapes and how many it could do in a set time. The NXT brick stores the programs you write in the brick.

good work!!!!!

[chewbarf]

lol u could make like a CNC Mill out of that lol nice job cool dude

[polskaswinia]

hej nice work

[ipoddhill]

will you e mail me the building instructions

[222Doc]

never did any for this, though this is a rather simple project. I used some lego wheels on each side, they are powered by the side motor, this makes the paper move forward or back as needed.

[diegodaudt]

is that a Sharpie?

[222Doc]

Circles; well somewhat, it would have been more complcated program. Also the more angle you atempt you see a zig zagy aspect to the figure. The rotation resulution of the motors is good but you will push those limtes soon if you try to right too small or with steep angle. From the distance this is filmed the lines seem smooth but if zoom in you see this zig zagyness.

can it draw circles?

[Delfinigirl]

Can you give us a bilding instruction, please?

[ronaldmcrae]

Nice work.

[Volatus]

Wow! It's a vector printer! :D

Sweeeeet. Now make it print my 400-page movie collection. Double sided. With pictures. <.<

(j/k...)

Excellent work! :D

[222Doc]

lol

[finnpetter]

search for 'it-printer' or 'finnpetter' to see a lego printer i made and programmed in just 2 hours.

[loffesenior]

nightmare to program?

[222Doc]

its in nxt-g. that makes things a bit simpler. but i had to borrow a few tricks that Brian Davis documented in the use of "crowbar's" in a loop.

[ibon1994]

u no dats some sick work man most of these lego creation a crap

[12alle12]

nice work

[hunterxd2]

thx for the brick link tip. it goes via pay pal isnt it? i hope so i have 40 dollars on it

[222Doc]

yes most only except paypal, some even take visa. check the sellers splash page. each seller is seperate, bricklink is kind of a ebay for lego, but much better

[hunterxd2]

thx m8 now i have bought that rails for technic gears

[AidanHockey34]

wow great work. im guessing that you were inspiered by tilt-a-ped`s weight shifting mechanisim and turnded it into a ploter.

it runs smooth and true. lol love the name, very original!

[222Doc]

only had to borrow the track gears, fairly simple to build. Program was bit harder had to learn Brian's "crowbar" to get multi threaded programing in a loop.

[AidanHockey34]

makeing any type of shape or letter is hard.

so, in the end, this program works great!

btw, were do you get your track gears?

i have tried L Ed but i dont want to spend $10 on 12 track gears. bricklink sells them for about $.14 each.

[222Doc]

bricklink is the better deal. though at the time i had a large order from LegoED for gears and pneumatic parts so i did order them from ED. you also get 10 worm gears, but still it is 45cents a part. go bricklink for them, though you need to find a seller that has alot, they tend to be more per part when they have many.

[marjan15]

what about a circle? :)

[222Doc]

possible but much harder to get smooth lines. a few test i did they came out kind of jagged. its hard to see but even the diamond/triangles are not smooth abit jagged.
