Wild Thumper, progress but help/advice requested

Hi all,

I had a lot of trouble with motor driver boards and my Wild Thumper 4WD chassis - in the end I bought a more expensive motor controller said to handle 60A. I am controlling the paired (left/right side) motors by PWM signal and  it now drives forward/backwards/left/right etc.

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.

Wild Thumper 6WD & Encoders

Hi all!

I'm the owner of Wild Thumper 6WD without encoders. It's really hard to get WT 6WD with encoders or motors for that platform with encoders at the place I live in. So I have to solve this problem in different way. Could you help me with my questions?

1) In basic model of 6WD with encoders on which axis encoders are installed?

2) Does it make sense to put encoders on all six wheels?

GY-521 and motion in a straight line

Hello all

I have a few questions about using GY-521 MPU-6050 gyro. If you have experience - please, help. 

1) Different sources indicate different allowable voltage - 3.3V or 3.3 / 5V. Can I use it with my 5V Arduino?

2) Is GY-521 enought for motion in a straight line of such platforms as dagu 4wd/6wd wild thumper?

Many thanks in advance.

Few questions about Spider Controller (DAGU)

Hello all!

I'm newbie and I have few questions about Spider Controller (from DAGU).

1) When USB is plugged and the battery is plugged too - which source of power controller will be use for servos?

2) As i understand, If i use analog servos I should plug it to PWM-outputs. And digitall servo can be plugged to any output. Am i right?

3) Can't understand what is the role of ON/OFF switcher. It is for battery only?

 

Many thanks in advance.

Droid Planning

Firstly Thanks to Oddbot, Pome & the Dagu team for this amazing Robot.

Assembly time was about 16 hours, that included rebuilding the right wrist to get the servo in a position to be able to pour a liquid ;-)

Review: The Service Droid kit from Dagu

I have received my Service Droid kit along with the Rover 5 robot chassis on a Monday evening. Excited, I opened up the package to reveal 2 big boxes, one with the Rover 5 and the other with the actual SD kit. The base comes assembled, with a battery box, a screwdriver (with a magnetized Phillips end), an Allen key (hex wrench) and a little bag with silicone lubricant. The droid kit comes with lots of parts grouped in separate labeled bags for easier assembly. To do the assembly, I used a cutter, a plier and the screwdriver from the Rover 5 box.

Getting Started with the 4WD Wild Thumper

Hello,

This is my first post here.  I'm sorry if these are very basic questions.

Wild Thumper Responds Briefly to RC, then stops

[apologies, I was sure I posted this but cannot find any evidence of this post on the website. Please ignore if it is a dup]

I have a Wild Thumper on a standard Dagu chassis using the sample firmware.  Flysky 3-channel RC transmitter, hooked up to D0, D1.

7.2V nicad charged up and attached.  Demonstrated that the motors are driven using the diagnostic Arduino Wild Thumper code.

With the RC, I can get the motors to move in the right direction (power, steering) for maybe a 1/2 second then it stops dead.

This suggests something about the current sensing.

[ARDUINO] Spider dagu burn

hello everyone. 

I recently acquired a Dagu Spider malheureusment but I have a little problem that I would like to expose you BEFORE testing it myself. Because Dagu has cost quite expensive for my small ways! And my first test has not been very conclusive. So i have questions :

I'm using :

- 3 servos connected (D13, D12, D11). 2 Tower Pro MG995 and 1 Micro Servo 9g.

- 6 alkaline batteries 1.5 V LR6 - AA

 

.... the board heating  and no LED lights. Is this normal?

.... Am i using a bad batteries ?

New Dagu Rover 5 w/4 Motors, Encoders

Hi LMR

I just received my Dagu Rover 5 along with a Redboard controller (Sparkfun arduino) and Rover 5 Motor Controller, all from Sparkfun Electronics. I'm not looking to take over the world with an army of autonomous AI miracle machines, just start a fun hobby with my kids. We have just unboxed the stuff and haven't began any assembly.

Wild Thumper Controller Compilling Issue

Hello:

I recently purchased a Wild Thumper Controller for my Wild Thumper . I tried to modify the controller software to use a LiPO battery and to test my ability to compile the code. Unfortunately I ran into several problems. The Fist was:

I was using the 1.0.5 Arduino Compiler:

Reverse pendulam using Rpi,Arduino and additional 0.75kg - which rover 5 chassis to buy

Hi

 

i am trying to built a autonomous car ( which can also be controlled by wifi) using DAGU rover-5 chasis , dagu 4 channel motor driver , raspberry pi (for wifi and camera) and arduino uno. i also like to use the same platform for inverted pendulam project using MPU6050 which is my next stage target , so the car needs to be very swift or agile to maintain the balance and change the direction.

can Dual H bridge 2A motor driver work with DAGU Rover5 chasis (2.5 stall current)

Hi

i was planning to Buy "Rover 5" 2 Dc motor , 2 encoder chassis from hobbyking with other accessories. however as a motor driver i found - "H-Bridge Motor Driver" which provides output to 2 motor but max current is 2A. whereas stall current for the motor is 2.5A. can i run the rover 5 without burning the motor driver?

rover 5 w dagu 4 channel motor control hardware problem?

I am running the dagu Rover 5 (4 motor/4 encoder verion) using a Mega2560 and the Dagu 4 channel motor control.  This is my first attempt at a robot, but do have some experience using several models of Arduinos and motor controllers. 

The code I used is from this first message (by Nick Gammon) and wired exactly the same: http://forum.arduino.cc/index.php?topic=82618.0

Dagu Playful Puppy Robot

Hi, i have bought the Dagu Puppy Robot and built it according to instruction manual. But the hip and feet movings doesn't follow the code. Even if i put the command "return;" in the main loop, the servos still move randomly (please check the video clip).

In the video clip i've plugged out all pins except one for test purposes.

Connecting LEDs to the 8 pins and with suitable code the board works fine. Could anyone help me please?

[SOLVED] Burning bootloader to Arduino Nano from Dagu Red Spider via circuting

So I recently got an arduino nano, but it came without a bootloader. I am trying to burn the bootloader by using the only other board I have, which is a Dagu Red Spider. By looking at the schematics, I figured out MSIO was on pin 22, MOSI was on pin 21, SCK on pin 20, and SS on 19. I connected those to the Nano's pins 12, 11, 13, and reset, respectively. Unfortunately, it still gives me "avrdude: stk500_getsync(): not in sync: resp=0x00" error.

Can anyone offer me any suggestions?

Dagu Magician Arduino Compatible Controller Board

As long as I'm waiting for the delivery of my Arduino UNO board, I have a "Dagu Magician Arduino Compatible Controller Board" bought low.
The instructions can be found here ... DAGU Board Manual
But I do not know on what kind of board I should put the Arduino IDE.
The board operates one ATMega8.

Has anyone ever used this board and programmed? I would appreciate help.

Dagu Rover 5 2WD + 2Encoders + PCB + Arduino Mega + Pan & Tilt with IR

Hi All, As a complete novice at this I thought it would be a great idea to get a Dagu Rover 5 with the addons for the kids at school and start up a club to program it. How wrong I was! I am in need of some serious help guys... I've managed to plug everything in, the 2 motors and encoders on the underside of the PCB board and have chosen not to use the 6xAA battery pack (9V) in favour of a single 9V battery (fits better under the PCB with all the cables). Problem number 1 is this: I think I am plugging in the black and red cables into the PCB in the correct locations - on the top

Arduino Uno + Dagu 4 channel motor controller - power issues?

I have an Uno controlling a 4 channel Dagu motor controller with encoder support. Got this a month ago. (It's the red PCB version).

Although it works, I have read that I shall not power the motors before powering the control logic.

But does that really mean that if the controller voltage dies out in the field, and there's still juice in the motor batteries, the Dagu controller will burn ?

I saw OddBot said this might be the case, at least if you powered it up in the wrong order.

Dagu Rover 5 Asymmetrical Encoder Output Problem

I'm having problems with Dagu Rover 5 with asymmetrical encoder outputs.  They do not have a 50% duty cycle and when the two outputs are decoded they don't give the same count going forwards as backwards.  I'm using 74HC14 Schmidt Triggers with a Teensy++ 2.0 and 4x encoder library.  My fix is to count by 1's going forwards and 1.75 backwards.  Is there a way to fix these encoders to have a 50% duty cycle?Dagu Rover 5 Encoder Output
