A deleted scene from Iron Man 1

I think you guys will appreciate this scene from Iron Man 1. 

SmartRap, build has moved forward

Between job stuff and family priorites, my SmartRap doesn't build by itself.

But little step by little step, I have nice progress :)

The build itself is ready, I started to plug and test things.

This evening, I flashed the Marlin firmware and tested the head servo.

Enough for a tired man todey, hope to continue to plug the rest of the cables soon.

Controlling a Raspberry Pi / Arduino Bot from the Internet Part 3 of 3

This is part three of a three part Series to explain how I control my BotTwo semi-

R1D1

This is my first robot project.

I am an electronics and computer systems engineer with over 20 years experience.

The Mailman

 

Long time no see...

I just wanted to share with you something I worked on during the month of January. I particpated in a robot competition here at M.I.T called MASLAB. My robot and team ended up taking 1st place. The details can be found on my website.

I'm sorry that I don't have the time to write a proper robot post about it on LMR.

Learning Electronics Via The J5 Obstacle Avoidance Robot

Hello to the LMR community. This first blog post is basically just an introduction for me and what I am about.

 

Creating a Picaxe 08M LCD Driver ( 2 wire Driver )

A few weeks back I decided to make another attempt at driving an LCD using picaxe. My first attempt was almost a year ago, however when the $6 LCD failed to display anything I wrote it off as defective.

But after a long night where i found it hard to sleep i stumbled on a  site that should me clearly how to power up and set the contras with backlight on. 15 minutes in and i was hooked. LCD light boxes displayed as i adjusted the contrast using a 1oK pot.

SmartRap received

Here we are: I received all the parts to build my own SmartRap

For the moment, just a quick unboxing:

LMR in Google

I am replying to the message Frits posted on the start page.

I did a qick check about the google presence and there is no sign of disappearance. I am sure it just had a small hickup due the website changing (owner) and/or registration.

As we all want LMR to be the #1 I am also putting links whereever I see fit. Please do the same but do not spam other forums, just place the link where you think it's appropriate.

 

Dagu Robotic Arm 6DoF - Bacuri02 Project

I recently received my Dagu Robotic Arm 6 DOF with Arexx control board 32 servos.

My original project is to use an Arduino Mega to control the arm and then make a wifi connection joystick control.

As I have not received my Arduino Mega board, I started tinkering in Arexx control board that I received along with the robotic arm. Along with the kit also came with a CD ROM which I believed the program to be installed on the computer to control the arm.

Now that was FAAAST!

Hey there guys,

A week earlier, our fantastic LMR member Lumi was kind enough to sponsor me a gripper arm and a pan tilt bracket (for 3DOF). I was planning to use it in a project for a local exhibition. More on that soon! Let's see how the shipping went.

Mega blocks - DRC seeker working...

Well.... I set myself the task of creating a robot that would learn an object then go and find it using vision....

Mission accomplished.... well, its probably not very robust but that's a problem for another day...

Today's task was the Mega Block challenge -  an area bordered by Mega Blocks (it's what the kids use and have quite detailed images on them that I can use as objects to find):

Short post on Successful data out of OSLRF-01 Laser Range Finder

It's late and I'm going to bed. My eyes are blurry, and I've got a headache... but!!!

I'm getting reliable (for the most part) Distance readings out of the OSLRF-01 as evidenced here in my putty dump.  The "ACTUAL" distance to target was in fact 2.67m.  I've got a fairly consistent reflection or ghost at 0.67 and few more stragglers that I will work to filter, but I'm quite pleased.

DRC: object recognition using Raspberry Pi

Well... now for some simple object recognition...

The program flow:

a) take an image; take a subsection as the reference object - calculate and store the SIFT descriptors for this image

SIFT descriptors

b) rotate DRC by 180 degrees.

c) take an image

d) calc SIFT descriptors and look for matches with the reference

e) if not many matches - rotate a little and go back to c)

Prototype of OSLRF01 Arduino Scanning LIDAR (Under $150)

I've finally got pictures to show off the OSLRF-01 Open Source Laser Range Finder.  I've mounted it to a sturdy servo, and am running both currently with An Arduino FIO ... simply because that's the only available Arduino I have at the moment. 

I am also getting boards made up around the ATtiny84 that will sit as a daughterboard on this unit.   But the FIO prototype is to help me get functional code working NOW...

Biped Howto: Moving servos

+++ UPDATE (12-march-2014): Rename title as "Biped Howto".

Hi, I will try to explain, in a very simplistic manner, the way in which servo motors can be controlled.

Servo motors are controlled by a PWM signal, in which the active part of the signal (known as duty cycle) define the amount of degrees the servo will rotate.

AI.Frame funding

I've got in contact with the people behind the AI.Frame robots and there are some quite interesting designs. We've got some kits to try them. Now AI.Frame is going the next step and want to collect some funds for a first batch production.

You might recognize some stuff in the pictures. Yeah, my friend and me took that pictures in our DFRobot office.

Vader Vibes

Starting this blog as a place for me to throw down my thoughts about options for my Service Droid, VADER:

http://letsmakerobots.com/node/39884

At times where I'm anxious to work on Vader but can't, atleast I can blog about it!  Right now is a good example: my 2 month old daughter is asleep in my arms. I may be having to type with one hand but the progress feels good!

First off, I'm considering a tweak to the acronym."Very Advanced" is a little over the top. Maybe "Virtually Advanced" or "Very Amateur".

I just received my OSLRF laser Range Finder!

So I received this awesome package in the mail yesterday from LightWare Optoelectronics in South Africa.

Made In Nepal Expo 2014 : A Glimpse

Hey there guys!

Whenver there's a relatively huge event in Nepal, the organizers resort to "Bhrikuti Mandap" as the venue. So was the case this time. The Made in Nepal Expo 2014 was held from 14th - 17th Feb 2014, at Bhrikuti Mandap. 

As the event name suggested, the event hosted hundreds of stalls that ranged from furniture to clothing and from pottery to 21st century art-work, in short, everything that's made in Nepal. Of course, why would I post this if there weren't some robots on display?

Pictures! Your Up Next!

 

 

Autonomous Navigation Robot

The process of monitoring and controlling the movement of a craft or a vehicle from one place to another is termed as Navigation. By employing and implementing a suitable design, we can create a vehicle that can navigate from one point to another without a driver. Autonomous Navigation Vehicle (AGV) is an automated vehicle that does not require operation from an operator.
