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

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.

 

Idea for Treaded Robot

I've been meaning to show Dickel my experiments with Vex treads. His MDi #2 continues to look amazing but Dickel has expressed some concern about the frame of his treads. Rather than using increased thickness of polystyrene, I wonder if some sort of box shape could be used to increase the stiffness of the structure.

Here are some photos of prototype tread mechanism.

Smart Doodle Bot: ES100 MC Group 7

Hello!

My ES100 group will be building a Doodle Bot for our group project.  Since we haven't started building our robot, we are posting a blog about it instead of a project page.  Hopefully, we'll have exciting pictures to post soon!

Since this will be our first robot my group has ever built, please pardon our naivete.

We look forward to learning from this talented robot community!

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.

Smart Doodle Bot: ES100 MC Group 3

Hi everyone!

We're wrinting this blog as part of a college project for our ES 100 Introduction to Engineering and Design Class.  This will be the first robot we have ever made.  The purpose of this project is to make a robot that can draw, make music, and dance.  

We're purchasing the "smart doodle bot" from Hobby King to get started.  We put our order in on September 8th.  Hopefully, it will come in soon because we could only purchase it from Hong Kong.

BoB the Biped and Me: BoB finally gets his lights.

Finally got viable PCBs for the LED array. Even still I burned up two out of three of the boards and several microcontrollers with various mistakes but the last one was a winner.

Introduction to GR Sakura - Development board

Sakura? What's that ?

A royal sake brand ?Premium car Polish?(Sorry Oddbot ...had to put that in...)

A cherry blossom tree?(Well it means that literally!)

Simply put I guess you've never heard of it.But now you Are reading about it and if you're reading ..You'll soon Know about it.(Well that's rather my intention anyways).So here goes... the first introduction to GR Sakura Development Board here on LMR.

First lets start with a nerdy introduction...

Campus Party London 2013 - Aftermath

This is the place where you will find the detailed report, pictures, videos of the Campus Party event 2013 in London with the view of our Letsmakerobots guys (well, and the guys from Roboternetz with whom we shared the table).

If you have been there then please let me know if you want to show or write something, so we can show it here in one big blog post.

Campus Party in London was held in the O2 Arena, one huge dome with a cinema, lots of restaurants and the big event area.

Morgan 3D printer adventure!

Thanks to Ossipee and his jedi mind tricks I have started working on another RepRap. My first RepRap was a Rostock which was on the cutting edge at the time and now I'm building another rather immature model. I have Ossipee to thank for the ongoing Rostock adventure as well!

Since the Morgan is so new, documentation is still in a state of flux with quite a few people documenting various virtual and real-world builds. While this is good it also has a way of muddying the already murky RepRap waters...
