Hello LMR Community!


 Hi Friends,
We've been watching and reading the LMR site for several months now, and we have really enjoyed it! We recently decided to begin posting regular blogs on LMR that will include customer photos, build logs, new product announcements, guest articles, helpful tech tips, and more. We hope you'll stop by every now and then to see what we're up to.  

For Halloween I Gave My Robot a Brain, or Fun With a Backpropagation Neural Network

I’ve long been fascinated by the concept of artificial intelligence and its application to robotics.

MAKE: Jaimie and the Giant Robot

Some of you know Jaimie Mantzel and his awesome Giant Robot Project. Well, a couple of guys are putting together a documentary about him. They've already shot all the footage, but they are looking for help on post production and with film festival entry fees. Read more on MAKE...

Hello , I am Josh Starnes

I started building robots beginning of last year. I live  in Tennessee USA.  There are not many local places to buy parts so many of my orders come from China or a couple choice online stores.  If I have everything I needed at once I would have a robot together in a matter of hours but it is usually the waiting game. I find parts , order then wait 2-4 weeks to get here and start back my work.  Though I am a begginner in robotics, I am a Jack of all trades. I can weld , solder , draw .

Mecanum Robot

In my blog about the Shanghai Maker Carnival i wrote about the workshop and our VIP guests but not much about the other stuff. here it goes, the other stuff. One of the interesting objects was the Mecanum Robot (well, actually remote controlled), a project of my colleague Angelo. He build that monster, improved, failed, improved again to make it work. You might imagine how much fun it was to test it in the office :-)

A win... but with a partial (82%) sour after-taste!

So today I finally got my hands on what I came to call my "DAGU loot", a selection of DAGU items that I acquired using the credit I won from participating and winning 1st prize on the Doodle Bot Art Competition with my Little Stella and her artistic talents.

First off, kudos for OddBot for issuing yet another Challenge and overall being a pillar of this community and DAGU for sponsoring it.

Maker Carnival Shanghai 2013

Well, I just want to review the Maker Carnival in Shanghai last weekend (Oct. 19 & 20). 

It was the second Maker Carnival in Shanghai and I may say it was a huge success. Many peopel came not only for watching but also asking questions and got in terested in the general Hacker/Maker activities.

DFRobot as a sponsor of the Maker Carnival had a booth showing new products and projects. Her you can see the Insect bot mini prototype.

Power Issue Solved

Quote of the day:

Is my robot a cyborg, becouse it has blood sweat and tears into it?

Hello everybody,

Yesterday I put this robot together, but it has a power issue.

Introducing myself

 
Hello everyone,
My name is Albert and I'm from the Netherlands.

Update on my status with BeagleBone Black delivery

Well, almost a month ago, Mukund showed me the BeagleBone Black over on facebook. Then, I was considering buying a Raspberry Pi and a Freeduino Uno, and since the company was located just 30kms from my home and had next day shipping facility, I was pretty happy with it. But Black had an appeal to me. It was both a Raspberry Pi and an Arduino Uno and better at it than the combination of both. All this and the fact that it was cheaper at that time, I persuaded both myself and my parents to buy it. Then started the problems

RepRap Stepper Driver v1.2 and Next Gen CNC

In the picture from top-left, clockwise to bottom-left: the terminal block (24V power up to 13A), the 2 X-axis drivers, the Y-axis driver (blue heat sink), and the Z-axis driver (blue heat sink), the Arduino controller (direction x3/enable x3/step x3), and just below the terminal block there is a small 9V regulator board to shift 24V down to 9V for the Arduino.  Everything is mounted on an MDF board, and the board is mounted with baling wire.

 

Funny story at my expenses

People, I already posted a pictures once hurting myselve. Now it's time again to get your laught at my expenses.

maybe you already know that from my facebook or G+ account but here we go again. 

What do you see? Ok, it's my big right toe... that much I will tell you.

Here another picture to make it more obvious.

Now, guess what happened?

Yantra 2.0 Robotics Competition

It was the biggest in our small history, and will definitely be a proud one to cherish. The Yantra 2.0 Robotics Compeition was held on October 1st, under the Covered Hall of our national stadium, the Dasarath Rangashala. It was organized by Karkhana, a company that's striving towards expanding the boundaries of innovation in Nepal, and Robotics Association of Nepal, the biggest national robots governing body out here. E-sewa were the event sponsors of the competition.

LMRians, here are a few glimpses of the competition. :-)

First blog entry

Hi Guys,

I joined this forum to make robots. I have never built robots. I understand software very well. I am  thinking of making a robot which has arms, moves arounnd and should play chess by lifting real pieces. I will post the pics once I complete the design.

Print your own CtC!

 

While I was at Maker Faire this year, I was booth-neighbors with the great Fredini who was 3d scanning folks the whole weekend. I was one of the luck folks to be scanned!

 

If you want your very own, printable Chris the Carpenter, please visit:

Very clean designed DELTA 3D printer

How does it look? Not only the design but the printouts are pretty neat as well.

As I know it start from about USD $1000+

How do you program a screen with Arduino?

How do you program a tv screen? I want to do it with arduino, so I can put it on one of my current robots, an entertaining stationary robot head on my desk. I provided some pics of the screen I'm using. Please comment.

 

Using gestures and voice commands to control the robot

Couple of months ago we decide to participate in Intel's perceptual computing challenge (http://perceptualchallenge.intel.com). The idea was to extend driver cockpit application to control Veterobot (http://veterobot.org) with gestures and voice recognition. We are using detected thumb position in 3D space. Position along horizontal axis is used as a steering signal and distance to the camera (depth) to control acceleration (forward and backward).

It was a fun exercise but some more tuning is still required to achieve smooth control experience. So it is work in progress.
