Let's Make Robots!

The Write-LMR-Challenge

LMR_logocontest.jpg
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 ;)

Oh, wicked!!

On the R / the last turn, Id spin rather than slide.

Cool, thanks for taking up this old challenge again :)

I think this one needs to be added to the entries:

May not be submitted / oficial, Dan? But It's on youtube, and I love it :D

BaseOverApex's picture
Yeah, Dan. What are you thinking!??!!?

There would have been a lot of effort in programming that.

It would be good publicity if we could have this competition on Youtube. More interesting than their staring contest (except for the Jessica Alba entry, she's cute). Other robot builders would have to join to enter the competition.

fritsl's picture
Do you know how one can get such a competition on youtube?
OddBot's picture

I've never had anything to do with youtube before I started posting videos for here.

After reading their guidlines and revisiting the Jessica Alba video I watched it seems that the video is just like any of our videos that we upload. (do we know any celebrities? she has 7.7 million views after about 8 months)

According to your stats a lot of people found us through search engine results, we should try and utilise that.

It seems to me that we should just upload some good LMR writter video's with a competition annoucement attached at the end. Adding a few words such as competition to the tags should help. The Logo kit is a good start but better video tagging will help a lot since this is what search engines look at. We may need to look at what words we can add to our tags that will help to reach a wider audience such as cool, funny, prizes, competition etc. We need a couple of our videos to go Viral so we need some weird and wonderful machine doing some outrageous things. 

Video YDM busking in the street. Maybe I should have SplatBot run around in a shopping center with some money on a stick and then squirt anyone who tries to take it?

Some of my recent videos have had (not by design) names that may attract other viewers (drunken roo and wet dream). I'm watching them to see how their view ratings perform compared to the other videos with more boring names. So far after less than a week "drunken roo" has 116 views compared to 78 views for "Oh no"even though both were posted at the same time for the same project (pictomatix). After only 2 days "wet dream" with 115 views is outperforming "splatbot mkII demo video 4" with 90 views. This is not conclusive at this point. Give it a month or two but if the titles are also looked at by search engines then we should consider more interesting names than "splatbot mkII demo video 4".

I'm now editing the tags on my better videos to include words such as cool, firepower, fun etc depending on the content.

absolutely amazing!!

and what a nice type font   ;)

OddBot's picture
I've pretty well sorted the font to keep the letters vertical instead of radiating outward from the centre. But in this attempt I did not allow enough time from when the pump first starts to when it's actually writting. It takes about 1/10sec for the water to start flowing. Once I've sorted the new nozles out to increase the pressure I'll probably have to adjust it all anyway.
Ant's picture

how about a sensor that detects when the water flows, ie two pins at the nozzle that measures resistance,or one of those switches that have the long metal  bar that will get pushed out of the way from the water? Or is this all just overkill when you can just use a delay?

 

OddBot's picture
The time it takes for the water to reach the nozzle is pretty constant. When I changed the code for the two colours I didn't allow for the pumps stopping and starting again. For example, in the video, The R starts up higher than it should because I forgot to add the delay. Once I was on the beach it was too late to change the code.
OddBot's picture

Partial success! My new font seems ok but the two new nozzles on the cannons have a slightly larger hole which is dropping the pressure. The letters are not as high as they should be. See the video for a sneak preview of SplatBot MkII.

fritsl's picture

Wow, so nice, so cool!! I have nver seen anything like this.

Let me be the first one to comment "Demolition Man" :)

An arty suggestion: Let the font be in one color, but add a square around the text in color 2. ANd to look really cool, Start by making the square! :)

 

Can't wait to se the final work, thanks ever so much for sharing progress, it's highly entertaining and inspiring!!

 (I'd really wish it was my project!)

OddBot's picture
I hope this will inspire your creativity. As for the square, I'll give it a go but I might set it up with a different font for writing on a wall. I don't know how square it'll be after translating it to allow for the radial component. We'll just have to see. I'haven't found a wall that I'm allow to discolour yet. At least the ocean cleans up my mess on the sand.
OddBot's picture

I considered a wall but as the water runs down it will ruin the letters. The other thing I was considering was visibility. The water shows up well on the road.

I'm now replotting the text to compensate for the radial output.

The top shows the points plotted against servo positions.

The bottom shows how it should hopefully look.

This should make a big improvement on the next video.

fritsl's picture
Wickeeeeed!!!
OddBot's picture
This is SplatBot's 9th attempt at writting LMR, the wind wasn't helping so I'll try again on a calmer day. I'm also changing the font to try and compensate for the radial movement of the gun.
guibot's picture

very good endeed!   congrats  ;)

perhaps you could try a wall instead of the floor?

BaseOverApex's picture

Yes, I'd definitely go for walls. It would be more easy to calculate the "squirt vectors" if you're working in a 2D plane on a normal with your squirt gun.

That said, this is already VERY IMPRESSIVE!

fritsl's picture

OH YES!!!!

I'd say this is the first robot REALLY meeting up to the challenge!!

F*ck me, that is so cool!!!

WhizzyWriter.JPGHmmm...

Too tired to post WhizzyWriter details right now.

Maybe tomorrow.

All this arty stuff's killing me. Here's the home movie.

OMG, its awesome.. Greath job, think its a auto win hahaha

 Its crazy well done.

but does this one qualify to enter?

Of course it does!
BaseOverApex's picture

 Does THIS count as a robot, or do I need more wheels?

BIG SMILE

Well done BOA. Oh, the many ways in which this website is keeping people from doing what they were planning to do in the weekend!

Make those knobs turn and let that be your propulsion and THEN you can call it a robot! At any rate; we ARE expecting a technical follow up post!

BaseOverApex's picture

Dominoes.jpgI don't have time to do this myself, but if someone else does, please feel free to pick it up and run with it.

This is a video of a little $8 toy which lays a trail of dominoes behind it.

It's steerable. My thinking is that it wouldn't take too much to stick a servo on the steering head. It already has a drive motor. It doesn't even need an H-bridge control as it has no requirement to ever go backwards.

It would be sweet if someone could write LMR in dominoes!

I'm afraid I can't remember where we got the toy, but it couldn't be too hard to replicate.

Unfortunately (see video) it sometimes knocks them over. Need a better mechanism.

guibot's picture
While coding new interactivity into Farrusco, and trying to achieve more control on the way it moves, I though it would be cool to see what happens if I mount one little servo to hold a pen, and tell him to write ‘LMR’

This is the result  :)         http://letsmakerobots.com/node/2306

(Using a little Dutch influence, there to wow the judges.)

 T12_Attempt_1.jpg

For my next trick, I think I will try to get a servo to operate a paint aerosol. If I can do that, I can mount it on BigChaser and go and grafitti LETSMAKEROBOTS on the road outside my house. Actually, I think there's a big fine for doing that. Wait a minute, if my robot does it, no-one would know it was me!!

Pop Quiz: Can anyone tell me what this represents: ABEKLMORST ?
robologist's picture

the letters in Lets Make Robots

or alphabetizing as you said

BaseOverApex's picture

 

Did I give too much away? Yeah - that's what I was looking for. Nice, though, that one instance of each of the letters in "letsmakerobots" is an anagram of stromkabel.

 

fritsl's picture

stormkabel?! i kinda like that! stormkabel.com is available :D

I also like your robo, BOA :) Thanks! (a little pathetic, but I still like it :D)

BaseOverApex's picture

You're just sore because I don't grasp your notion for stalking plastic heads. ;-)

stromkabel - Electric Cable
BaseOverApex's picture

All the letters in the word "stromkabel" arranged in alphabetical order. A BEAUTIFUL coincidence (you'll see why later), but not the answer I was looking for.

 

BaseOverApex's picture

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.

Just look at all the blog repeaters out there:

http://www.google.nl/search?q=The+Write-LMR-Challenge

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

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

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.

BaseOverApex's picture

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"?

fritsl's picture

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
Nick's picture

Can i build it with nxt?

or else i dont stand a chance.

:P

fritsl's picture
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.
fritsl's picture

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!
