Project 2: Tidying up

Last two days have been frustrating - work has prevented me from working on developing my skills.

I did, however, manage to shorten the huge loom of wiring that came attached to the motors; there was a little board with 6 straight-through connections already attached near the motors on the base, so I soldered the 2 wires of each motor, plus the battery wires, to one side. The other side i continued the connections to the motors shield.

Project 2: And so it starts...

So, today, full of motivation (now I have figured out a rough plan for my project), decided to start learning the techniques to help me build my project.

Today, using a donated toy base (tracked, with 2 12v motors and gearboxes to boot), I added:

  • an Arduino Uno
  • Arduino Motorshield
  • Two 4xAA battery packs (in series to provide 12v). 
  • A Bluetooth module.

Using some arduino code I had developed for my Wall-e task I was able to move my tank around - ruddy good times!

Project 2 - my first project!

I've always has an interest in robotics and suchlike, however never really committed to taking that interest forward; coding and suchlike are my favourite parts but i am inept when it comes to the hardware side.

I keep going through phases where i plan to learn, to do... but never do.

Recently i actually started a project, however - to take a Wall-e toy, rip out the innards, give it a few motors and servos and add an Arduino (with motor shield and bluetooth Module) to keep it together.

ADC0809 AD 8 Channel Analog to Digital Conversion Module and Propeller QS

OK, so one late night I bought one of these with the thought of using it on a Propeller board as they have no analog inputs and it be really nice to have some for motor driver current sensors and other sensors that are analog. Now after learnig a bit more I see this will eat a lot of pins on the Prop and to be honest, I have no idea how to make it all work. I think I understand the code. 
lots of questions abound...

super fast robotic arm!

OK, I never thought we would see this so soon....

Using the Arduino PID Library for precise position control of X and Y axis on RepScrap printer

I've updated the test code I'm using to manage my X and Y axis DC motor / linear encoder closed loop controller.

A simple HTTP communication protocol between wifi and Arduino

How to let the sensed data (e.g., temperature) on the Arduino send to the remote server? 

The following code is used to realize this function.

void setup()

{

 Serial.begin(115200);

}

void loop()

{

   int n=analogRead(A0);

   float vol=n*(5.0/1023*100);

   upload_sensor(vol);

   delay(5000);

}

 

void upload_sensor(float vol) 

     // send the HTTP PUT request: 

     char buf[200];

Further Progress on framing my RepScrap 3D printer.

Well, this is what the RepScrap looks like today.

 

Arduissimo: MultiCore Arduino indiegogo project

Well I am core crazy, or is that crazy at the core? Maybe it all the 64 core servers I support.... But whatever, had to share this!

Yahmez Goodies!

On the 20th of April, I got a quote from the post office reminding me to collect all oversized packages that did not fit in the mailbox. Surprised ( as I did not had a mailbox ) and curious ( wondering what might the oversized package be! ), I rushed to the Post Office with the small piece of quote in my hand. ( That's the unofficial system we have out here! )

 I retrieved the package that mentioned PRIORITY MAIL in BIG LETTERS. I flipped the package and the entire story became crystal clear as it read " Robot Parts x 10".

Robots Ready to Rumble!

Maker Faire NYC will be here before you know it… and, it’s a great opportunity for thousands of people to see and interact with all the cool robots you’ve made!

Aren’t able to attend? No problem, you can ship your robot to us - and we’ll take care of the show-and-tell.

Xinjiang, robots and bombs!

Well another year has gone by and it is time to visit Xinjiang again. Xinjiang is far north west in China and borders onto several other countries. We regularly attend their science festival in Karamay and then go for a short tour around this beautiful part of China.

My Repscrap: DC motors and rotary encoders for Z-Axis too?

 

 I took a few pictures this morning, to give me something to think about while I was at the cottage for the weekend.

Why I Respect my Robot Elders

I've been forced to take holiday from work, Bek has closed my lab until June 1st, and I don't do down-time well.  Given I'm without a lab for the moment, I'm forced to seek other outlets for my brain.  So, I thought I'd write a few reflections regarding my experiences at LMR in the last two years I've been a member.

I thought I'd write about something I've noticed about LMR in regards to the influx of knowledge: Respect for our Robot Elders.

What's a Robot Elder?

newbie

Hello guys and girls,I am a new user and would like to gladly greet you all.I am terrible with robots but will improve with the LMR community.This blog entry contains a few ideas I will soon use to create some robots . Idea number one is that my first robot will be a line runner.I have not come up with a design but I know it will be very simple.The whole point of creating the robot is to improve my skills with robotics. My second idea is a navigator robot which will lead to the destination that is pinpointed.

beware of sainsmart!

some of you know about my experience with sainsmart some of you do not. and some have had their own.

this is a warning to all new people that may be interested in buying from them . DO SO AT YOUR OWN RISK

Just when you thought your robot costs are out of control...

Saw this on the Robotics Tomorrow website. When you watch the video, at first you might think he's a cute little guy, but actually, he is rather large, and EXPENSIVE! Starts at $50,000  
Makes the cost of what we make seem so affordable. Next time your significant other complains of your robot expenses, show them this bot... (he is rather cute though...)

I am a giant!

     Because as you know your height is the same as the distance from  fingertip to fingertip.   And the distance between my fingertips is over nine miles.

     And that means you have to be careful when using butcher knives.

     But don't panic, it was only about mm lost.  But that’s not to say i wasn't attached to that particular mm.

     So before using any kind of cutting tool think of the worst case scenario and don't have your fingers there.

A Military Science Exhibition/Competition - MSTC

Hello there guys. Long time no see. I was wrapped in a US college application season this year so got a bit busy with things.

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.

please find the attachment.

thank you.

Why I Hate Arduino

The title of this blog entry is going to make a lot more enemies for me. Not that I need any help there. But perhaps the content will take some of the edge off of it. I really don't hate Arduino, but there are a lot of things about it that bother or concern me, and some that just downright irritate me. And, to be honest, many of the things that bother me about Arduino is how people (try to) use it beyond it's reasonable capabilities. But the Arduino does little to alleviate that, and that again annoys me.
