Let's Make Robots!


Our First Robot - Build Day 1


Ever since we purchased our Arduino and tinkered around with a few simple electronics projects, we been itching to make a real robot.  Well the time has come where we had a few extra dollars to spend and we splurged and purchased the following to help us along:

Number up to 180 from C# serial print mapped to servo movement

Okay, I'm thinking the title probably isn't very descriptive but it's late and it's the best I can do. Basically, I've written a program in C# (I shall unveil this on here in a few days) that ouputs a value between 0 and 180 based on certain conditions. I want to be able to take this value and print it over the serial and read it at the Arduino end as an integer, so i can just have myServo.write(int).

At the moment, in C# I'm using sp.Write(int.ToString()); but I can use the same command to write a byte array and a char array.

Arduino Blutooth

Hi I have an android phone and i want to be able to send my text messages, emails, and other stuff to my arduino by using bluetooth. Is that possible? How would you get the phone to send that?

New DAGU products for 2012

Well 2012 is off to a great start with a brand new Arduino compatible controller, A car controlled by your phone and a robot arm with teaching pendant from DAGU.

The Micro Magician is designed for small robots running on low voltage batteries. The controller works on voltages from 3.6V to 9V.The heart of the controller is an ATmega168 running on 3.3V with an 8MHz clock. Check out the great new features!

Basic "Start Here" Robot (with Arduino)

I am brand new to robotics and I am about to try and build my first robot as a learning experience to get familiar with the basics (based on the "Start Here" design by Frits). I'll be using and Arduino Uno board instead of a Picaxe however.  After reading some other posts I have come up with a list of parts and several questions. I actually have some of these parts already but wanted to sanity check that I am on the right track. I am pretty comfortable with learning the programming aspect of this but want to make sure I have a good start on the right hardware configuration.

ATTiny programmer shield

I got some ATTiny and now need to transfer the program from the Arduino IDE to the ATTiny without a programmer.

The solution is, just make your own programmer shield. Based on this tutorial http://hlt.media.mit.edu/?p=1229 I created my programmer shield for the Arduino Duemilanove. It's not pretty since it's just a ugly board out of my box but it works. Preparing the Arduino duemilanove according to this tutorial and then hook up the ATTiny into the header pin socket, open your sketch and click upload. Done!!!

Arduino/ servo/ RC basics

I'll start off admitting that I'm a complete novice at robot building, so pardon me for what is probably stupid questions. I have bought an arduino with the intention of building a robot and have an idea of doing so mainly with servos, and I know that I can probably run them off the arduino without any problems helped by the arduino servo library, but can I just plug them in directly to the arduino or do I need a resistor in between or something? And question 2 How do I make my robot controllable via R/C? How do I put those circuits(?) together?

arduino and SLAM


I am developing a robot platform for children for educational purposes. My aim is to build a sub 100$ bot with arduino brains. I myself is a good programmer, and if I were to do it for myself, I would use an ARM or a better platform, but I have to constraint this project with arduino.

I have already designed some parts, and I have access to a 3d printer, so it is going all well. I already have a servo/sharp IR sensor scanner, and currently I am using a tamiya tracked vehicle for platform.

So Oddbot. . .

As I sit here with a tricked out Rover 5, a 4channel motor controller and a Mega 2650, it occurs to me just how much I'm asking of a poor little, (well, for an Atmel--Maybe not so little.) microcontroller.

And so I wonder. . .Have you given any thought to a "Spider Due?"

Apologies if I've inadvertantly stumbled into the Dagu vault of secrets.

First Robot Plan

I'm about to start my first robot project so i thought i would document my progress, I don't imagine anyone else will be interested so i'm mainly doing this so i have a record.Controller PCB

For a project at Uni I have made a Wireless controller and a motor driver PCBs. They both include a built in arduino and communicate via XBees. I get to keep the PCBs from the project and have bought the ATmega328 chips, XBees and a chassis as these are the parts we had to return.

I plan to use this as a base for my robot and add more features as and when i can.

clearing a serial lcd with arduino

i was wondering if i could use a serial command to clear a serial lcd. i am new to arduino so any help  is appreciated.

Arduino Serial Question


I was wondering if anyone could tell me how to send a string to the arduino and just echo it back to the serial monitor but also create a NEW LINE.  Right now I got it to take a string and echo it back exactly but every time I send the string form the computer to the ard it just tacks the echo from the ard right back onto the end of the previous data that is showing in the monitor.  


For example: 

I get this:

Comparing multiple Arduino inputs



This is probably very simple, but is there an easy way to find which of multiple arduino inputs is greatest/least?

All I can think of is using lots of  if/else's. I tried googling it but found no relevent results.


I am thinking of between 10-16 inputs, so if/ else's would not be very practical.



Arduino Xbee shield problem


I am trying to communicate between 2 arduinos using 2 xbee shields. I am trying to configure the Xbee shield with PAN ID, address etc. I am using X-CTU utility on a windows 7 64 bit operating system. I am able to configure one of the XBee modules with all the necessary parameters. I am not able to repeat the same for the other module.
