Dagu Rover 5 & Arduino Uno /Help

Hello everyone.

I'm trying to make a robot for experimentation, something i can use in my studies aswell. I'm studying Electronics & Computer engeneering, first year, and i want a platform that i can improve in the years to come. 

I started playing around with LEDs and an arduino some time ago, this week i bought a Dagu Rover 5 with 4 motors and 4 encoders. The problem is i don't have the 4 channel DC motor controller. 

Building the perfect Beast (robot chassis)

2012 may be the year of the Dragon for China but it is the year of the robot chassis for me. I am trying to create a new range of robot chassis's and I'd like to know what features my robot building friends would like to see in a chassis. Obviously low cost and high quality are preferable but what else?

For example size? As far as I can see there is already a range of sizes on the market. Is there a size that's missing? I was looking at some cool wheels that were about 250mm (10 inch). Would you want a huge chassis and for what purpose?

DAGU Playful Puppy Robot Review

 

Introduction

OddBot (Russell) sent me a DAGU Playful Puppy Robot kit to check out. This little guy is really neat.

S.C.O.R.P.I.O.N. Potato cannon mounted on 6WD robot

Ok, to begin with it is just a normal SparkFun "new product post" but check out the last few minutes of the video. They mounted a potato cannon on a 6WD Wild Thumper chassis!

Who thought robots and potatoes could be so much fun?

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!

Dagu 4 channel motor driver fried

Hi,

I have fried my 4 channel motor driver and don't know how this can happpen. As you can see in the picture the Dual FET IC  U10 for motor 4 is blown away. This happened during a first test of my IOIO-SHR v2 robot. Before connecting the motor driver the program has been tested with an oscilloscope, all Outputs are working as expected. All connections has been double checked. Power supply testet with an voltmeter. Each PWM pin can be controlled from the Android phone with a Slider of my test app. PWM frequency was 1kHz.

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.

Question for Rover 5 users about alternate wheel options.

SO, having completed my holiday obligations, it's time for a little present from me TO me.  I've been collecting assorted parts, and experimenting with Arduino code and have decided that pretty much everything I want to do with a robot base can be most efficiently, cost-effectively accomplished with a Rover 5, and it's at the top of my "Been a good boy" list.

The only thing I don't like about it is those rubber treads that seem to keep falling off.  And since it's my intention to get the Rover 5 with 4 motors and encoders, I've decided to go with independent wheels.

different versions of dagu controller behave differently?

Hi,

I posted this yesterday in someone else's thread and was advised to start a new one.  My message from yesterday:

This is my first post, so forgive me if I break protocol.  I bought a rover 5 and then bought a dagu 4 channel controller from a british outfit (robosavvy) and was able to create my first robot.  Super cool!

This is the first prototype of the Balancing Robot. In this version , I used two sharp sensors to control the motors.this is as first step till the IMU comes from … Read more

Best way to Power an 8 servo - Quadbot

Hi. I want to power a Dagu Qadbot without sources, only batteries, but don't know the best way to Do it. It uses 8 micro servo - 8g, 4~6V, and draw a current that I don't know the specific value as I didn't find a Datasheet.

 

So, as I'm almost sure that only Arduino will not be able to power the 8 servos, I'm thinking about 2 solutions:

 

1st - Use 4AA Battery to power - the Arduino i parallel with the servos. This way I'd power the servos directly and just connect the digital pin to the arduino. 

This is my second puppy robot and the first to use a QuadBot kit. The robot is quite simple, just a pan / tilt kit mounted on a QuadBot chassis with DAGU's new … Read more

Support site for DAGU kits and products

G'day Everyone,

I have been designing products for DAGU for over 2 years now. During this time I have always tried to provide technical support and help in general here on LMR. I will still continue to do so but previously I had trouble uploading manuals because of upload limits.

This is modullo, one of my first elaborated robotic platforms. It hasn't got an actual purpose yet, I'm at the stage of adding various sensors and integrating them … Read more

Mapping of Pins on the Dagu Spider Motor Controller

I made a mapping of the Dagu Spider Motor Controller pins. The cells in red are what you see on the board itself. Other info has been placed adjacent to those cells for easy reference of functions, alternate names etc.

 

Curiously I am wondering if there is actually a typo mistake on the board with one of the pins being labelled as "TXD1/D1" when it should be "TXD0/D1" instead. Is that an error?

 

Please give feedback on the accuracy of the mapping.

 

Dagu Rover 5 shedding tracks on turns

Hi guys, Hope this is the right forum. I'm building a robot based on the Dagu Rover 5 chassis and experiencing problems with it shedding it's tracks. The motor angle is about 45 degs. Anybody had any experience with these and stopping the tracks coming off (even on smooth hardwood floor) during a turn? I'm hoping someone has done a modification or something to keep them on, other wise this Robot may be getting itself converted to tires :-( Thanks guys Shane

Rover 5 - Dagu Spider and 4 Channel Motor Controller

Ok so i recently purchased the Rover 5 Kit from Robotsavvy by Dagu.

With Help from Oddbot i have put wires from the encoder into the Motor Controller (in the right place i think)

But i have no idea which pins go to the arduino and also where on the arduino they go to.

 

Image of what ive done and the question :

 

Any help would be appreciated.

 

Bradley.

Problems with object tracking using a Dagu compound eye and pan tilt set up.

  Currently I am having problems with object tracking.  My current set up is a Dagu compound eye on a Dagu pan/tilt braket with 2 micro servos in it for turning.  All of that is hooked up to a picaxe 28x1 board correctly, but I run into my problem with my code.  My code kinda worked but was really jerky and will still move when there is nothing there.  Also sometimes it will go like it has a mind of its own.  I thought it was moving when there was nothing there because I made it read the two eyes on opposite sides and jus

Advice on building a pan/tilt robot arm

 

Hello LMR folks,

I am in need of some advice over a robot project I plan to build. I have a small amount of experience with using an Arduino, soldering and general circuit making, but I've never used motors yet.

What I plan to do is to have a "robot arm" attached to the ceiling with a camera at the end of it. The arm need to be able to rotate the camera around and depending on some conditions tilt it at different angles.
