Life with Little Free time!

Right... It has been Way to long since I have had enough time to jump back into this amazing community so this is a quick Catch up on what has happened and what I've learnt in the last 9 months! (Why-Lumi once said if it's not on LMR it hasn't actually happened! & Some Pretty AWESOME Stuff has happened!)

 

The Low down....(More Info will Follow)

Moved to Australia, Got a Crap 60hr a week job driving-NO TIME for ROBOTS :-(

The case for lurking on LMR before starting on a large (ish?) robotics venture...

Ok... so let me start with... I've been humbled by the sheer simplicity with which some of these bots on here are made.  Functional and clean.

 

The one article that has made me rethink my strategy the most is  Oddbot's article Pushing the limits with encoders  

 

Pushing the limits with encoders

This is now a tutorial and can be found here: http://letsmakerobots.com/node/39098

I've been working on some code so that a simple Mini Driver using a lowly ATmega8A can drive two motors with encoders and 8 servos. This may not sound hard at first until you remember that the Servo library kills PWM on the ATmega8. To make matters worse, D2 and D3 are the external interrupt pins but we need them for driving the servos.

4.5 Children

4.5 Children

Thought i would catalog these here as a first for LMR (4:11:2013)...... (before any other maker feels the siberian wind)

These are the first members to be added to my family of Matryoshka dolls .

I designed them with "Blender" and 3D printed on my "Ultimaker" at 0.2mm Zaxis step. (so room for more Vodka)

Dagu Classy Chassis

What more can we ask for..... Awsome presentation of our very own LMRer OddBots & Tyler (Dagu) Classy Chassis.

BirdBoard!

I think I'm the first (other than Bird himself) to finish a "BirdBoard."  It took maybe 3 hours and some frustration with the convention that has circuit layout software label both caps and jumpers with "C" but check it out-It works!  Now to put it on a robot...  Thanks to both bird and Ossipee for their help on this.  When I make a robot with it I'll tell the whole story again, but suffice it to say this thing really is an elegant little bugger!

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 .

Why are we so crazy? More lubby dubby bull$#*!

In light of the recent forum topics and discussions in the shoutbox I felt that I also would like to contribute the 'lubby dubby' bull$#*!.

I joined this site just over a year ago now. I was nearing the completion of year 12 and had been doing YouTube stuff for about 2 months. I had learnt how to use Arduino and had created several little creations. However, having a history with robotics I was drawn back to my robotic ways.

Raspberry Pi bot on RC 3 wheeler base

I have:

Raspberry Pi, geekroo board, 3-wheeled rc car minus controller from charity shop, assorted bitsnpieces from old toys, printers, scanners etc. like motors, gears, and such,not much knowledge but great enthusiasm.

I want to build:

A robot. Obstacle avoiding? Controlled with smart phone? Include a webcam?(RPI camera has been ordered)

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...

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.

WMRVersionAlbertENG

Good evening everyone,

I would like to share the WMR code I use to make my robot work. The code is based on a code with a German description. I managed to translate it to Dutch and after that I translated it to English. I would like some feedback on this, because it's quitte possible, that I made a few mistakes after translating two times. The command lines work fine, but it's the description. Fingers crossed.

Albert.

Protowrxs Prusa 3d Printer

So with so many LMR enthusiasts building, buying, printing, or renting 3D printers I figured I’d jump on the bandwagon and go along for the ride. I can really see the joy in being able to just print cool things off ThingiVerse much less the thought of designing some little mount, feature, cover or whatever for a robot you may be building.

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.

So, this weather hmm?

Ok, this blog is meant to post content related to the progress of my little garden monitor.

Objectives:

- Low power node (using an atmega chip)

- Measures: temperature, humidity, luminosity, soil moisture

- Reports it back to a central node (via nRF24L01+ modules) at specified time intervals

Service Droid V3.0

I was talking to a friend last night and he pointed out the Service Droid would be better on the Rover 5 Chassis. This is what I have so far.

The Service Droid is a cheap robot body with a reasonable amount of functionality. The idea is that you can fit it with whatever sensors and processor you want.

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?

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!

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.

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. :-)

Robotizing an old Power Wheels toy.

I recently acquired an old "power wheels" T-Rex kids ride on toy. So my choices now are:

1) use the drivetrain for a robot - I started a robot page but no progress to report yet

2) use the whole body and convert to a robot - could be a test-bed for self-driving vehicle
