Let's Make Robots! | RobotShop

The Write LMR Challenge

The rules here are simple:

  • Make a robot that one way or the other writes either "letsmakerobots.com", or "LMR" the way you like it.
  • Shoot it on video, enter it as a robot.
  • Best entries will be promoted / used to promote LMR - Fame, envy, marvel, admiration and respect is the prize!

Your robot can shape the letters in clay, burn it on your sisters dog with a laser, build them out of breadcrumbs.. or draw it with a pencil on a piece of paper. Anything goes, as long as the letters are clearly written, and the video shows the progress.

Sample code is VERY welcome - perhaps this can be done simple by a "start-here-robot" - that would be way cool, and with some simple code that others could adapt and try at home!

Make sure that you have plenty of light on the video - best shot outside in daylight - it is going to be featured, so we need it to be sunny ;)

I would be VERY impressed if a Techie could do this - I just don't think they are up for it, they would be making it too complicated :D:D

(You have been challenged, Techies!) Looking forward to see some cool Arty writers!

Can i build it with nxt?

or else i dont stand a chance.


Of course! Build it with wet paper towels if you'd like, as long as it is "a robot" that is writing LMR or letsmakerobots.com, that is the only rule.

I did this in Lego with my RCX. All I'd have to do to get it to write LMR is give it an alternative bitmap. (The two bitmaps at the bottome ar those the machine was fed with. If you click them, you can see teh results out from the plotter.)

Of course, I dismantled it when we moved house about 10 years ago, so, I'll not be entering this version, but if we don't get a winner, I'll rebuild it for publicity. Actually, this is only part of the project. I never finished it, but it was supposed to be a photocopier.

Question: what would make this machine a "robot"? Is a pen plotter within your definition of "robot"?

I would say that a robot would have to be somewhat mobile here to really qualify; A homemade plotter would be cool, sure, but I think the visuals would work better if

  • the output was larger than the robot, and
  • the robot itself was moving in order to fulfill the task

Just look at all the blog repeaters out there:


eggshell-robotics and botjunkie for starters. Let's just hope /. doesn't get wind of this story!

I told you; Fame is waiting for the first to make it :D
...even if it's just a floor turtle from the 1970's?

Yes, but of course!

And you can also change the fontface, if you want letters to be made out of the same line, use small letters (lmr) etc.

With respect to the burning of the LMR logo onto my sisters dog with a laser, can LMR give me any veterinary liability insurance? I suspect my sister will want the dog to have plastic surgery after I shoot my video in order to correct the tissue damage and to restore some of the fur.

Also, can you list UK suppliers of anaesthetics? I shouldn't want to test my canine laser tatoo machine with the animal still conscious. I suspect it will struggle resulting in the logo being quite unreadable. That's probably not really the image you want to advertise anyway as it would make the workmanship look quite terrible.

Can the deadline please be extended a little? The dog's leg is still in plaster as it got broken while I was testing my entry for the "Robot to Lift Your Sister's Dog to the Top of the Eiffel Tower" challenge last month. Stupid, really. My sister told me I should have incorporated a parachute.

PS - no animals were actually harmed in the making of this comedy message.
