Let's Make Robots!

LMR is going to Maker Faire NYC 2011

See us at Maker Faire!

What's MakerFaire?

From the MakerFaire.com website: "Maker Faire is the premier event for grassroots American innovation. As the World's Largest DIY Festival, this two-day family friendly Faire has something for everyone - a showcase of invention, creativity and resourcefulness and a celebration of the Maker mindset."


New York Hall of Science

September 17th and 18th, 2011


They are specifically looking for robotics (among many other things, of course). How can the biggest (and coolest) community of robot makers NOT be there?

Who's coming?

I need some more volunteers who are willing to spend at least four hours at the LMR table during the Faire. I believe four hours qualifies you for a day pass, and eight hours gets you a weekend pass to the Faire.

Here are the responses I have so far:

  • Me (Andrew Terranova, aka ignoblegnome)
  • flummer is coming from Denmark! He's volunteered to help with set-up, running the LMR table and tear-down. Good man!
  • GeneralGeek says he will come, but needs to leave town Sunday morning.
  • JoeBTheKing can come hang out at the LMR table for a while
  • Krumlink came to his senses and decided 15 hours from Michigan is too crazy... then he lost them again and said he might come down with his maker group.
  • TinHead will be in Boston sometime during September, and may be able to drive down to NYC for the Faire.

What are we doing/bringing?

Update 2011-09-12: Posted a video sneak peek of our stuff at MakerFaire. 

Here's what I wrote in the application for our project description:

LetsMakeRobots.com is the largest online community for hobby robot builders. At Make Faire, we'll demonstrate the famous Yellow Drum Machine (YDM) created by Frits Lyneborg, as well as other robots by our members. 

The YDM is a funky little free-range drumbot that roams around and makes beats on whatever he finds. He even samples and plays back sounds to mix with his music.

We may also have some fun projects for you to try yourself! If you've ever wanted to build a robot, you should stop by.

Our web page on MakerFaire.com: http://letsmakerobots.com/files/userpics/u2691/RBA1.jpg

Here's what we have so far:


  • Update 2011-09-11: Frits sent me his original YDM to demo at the Faire! He's all ready to go!

  • Patrick McCabe has offered to send along his maze solving robot.
  • Update 2011-08-31: Patrick is kindly including 3 sets of the AAA NiMh batteries his bot runs on. I have a charger that will work for those batteries, so we'll be all set for constant demonstrations.
  • Update 2011-09-11: I got the bot! I need to buy some white board to build his maze.

  • guibot is sending me a Farrusco kit!
  • Update 2011-09-11: I have the kit in hand. All ready to build at MakerFaire!


  • GeneralGeek may be able to bring his symet.

  • OddBot has offered to send me the original Chopsticks!
  • Update 2011-08-31: You can track his progress as he travels from China to the US!
  • Update 2011-09-11: I have received Chopsticks and tested him out. Some minor tweaks suggested by OddBot were implemented. I need to solder a connector to his power leads so I can connect the batteries I have.

  • Update 2011-08-25: I'm hoping I am going to leverage my preparations for an hands-on exhibit at the Children's Museum of Somerset NJ, and have some kits so people can come and make a simple robot at the Faire. The kits will be a simple SpurtBot line follower.
  • Update 2011-09-11: Design is finalized and I have most of the parts. Hopefully finishing this up today!

  • Update 2011-08-26: This just in... propellerheadgeek has offered to send me one of his Eric the Turtle robots! Laser-cuts sweetness.

  • Update 2011-09-12: Ro-Bot-X is sending one of his Robot Builder's Arduino (RBA) kits, which we'll build into something at the Faire.

  • JAX is frantically trying to finish a bot to send as well! Good luck, JAX!


Let me know if you can come. Also post your ideas, or if you would like to send something for us to display at the event. 

What's the setup like?


We should have a "standard" table with two chairs. I originally said we could be outside, but I just send the Faire organizers an email asking if we could be inside so the sunlight won't interfere with all the IR and other light dependent sensors on our robots.

Update 2011-08-25: We will have an indoor setup with two tables and four chairs provided.

Update 2011-09-11: We'll be in Zone A' on Robot Square inside the NY Hall of Science. Check out the MakerFaire NYC Program Guide.

I'd like to set up one end of the table as a "robot rodeo". We may build an edge around it so robots don't fall off too easily, and there will probably be a black on white maze for Patrick's maze solver and any line followers.


I've requested 15A AC power service available so we can use soldering irons, hot glue guns, recharge batteries, etc. I'll bring a power strip. I'll have a NiCad/NiMH battery charger on hand too.


We have a banner design by flummer, which I will look into getting printed locally. I'm hoping to bring along some aluminium poles to display the banner above the table. I'm also planning on a standing table display featuring the Logobot.

I priced printing for the banner at Vista Print and Cafe Press. Both came in at about $55. I'll check a local print shop and see if I can do any better.

Update: 2011-08-31: Shirts

Hey, flummer also designed some shirt logos! They will be iron-on transfers, so LMR members coming to MakerFaire should bring a dark colored cotton shirt they would like to have the designs on.

Small Logo for front-breast, pocket or sleeve:


Large logo for shirt back or front:

I did send the kit, have fun with it. I will have to order new boards with the name changed to the Robot Builder's R-duino (same pronunciation, different spelling), as the "Arduino" name is trademarked and it seems that I can't use it in a product without approval and pay a license fee. Let me know if you need the assembly guide, as I had to remove it from the site until I correct it.

Cool. Shoot me the tracking number via PM, if there is one.

I can probably figure out the assembly myself. You posted plenty of good info on your board.


My decision to go with something new and different has stymied my submission for the Robot Rodeo. I can't get my ultrasonic sensor to comply so my robot is dead in the water. It's too bad. I had that sucker playing high-quality PICAXE tunes with no way to shut it up hehe. There's nothing like Indiana Jones and Final Countdown belting out of a piezo speaker!

Too bad, JAX! I hope you succeed in figuring out your robot sometime soon, though. Sounds fun.

Since we can't have an outdoor table, I won't bring my symet. a solar powered robot without solar energy isn't very interesting....

If your still looking for robots I'll be happy to bring mine - not that they are that interesting - just a quick and dirty line-follower, and my variation of the SHR.

Let me know, I'm leaving for NY Friday afternoon.

Excellent! Bring 'em on!

We'll have some line following tracks set up for the SpurtBots and a maze for Patrick's Maze Solving Bot, plus materials to make more, so your line follower will have a place to play, and maybe some friends.

I'm going to bring my own robot, Penny, who started out as an SHR, got 'upgraded' to an Arduino, and may get another upgrade right at the Faire.

I am planning on being at Maker Faire NYC for most of Saturday.  I'll be bringing my walking robot with me.  I can show it off, but I can't guarentee how long or when it will be working.

Hey, we're sadly lacking in walking robots. Definitely bring it by for a visit, and stay as long as you like!

I just realized who you are and which walking robot you are talking about. You mean the 'Robo Puppy' that you showed at the Steampunk Worlds Fair a couple of years ago!

Awesome! Please do stop by. That thing is wicked cool, and it'll be nice to see you again.
