Rover 5

It can easily avoid objects and go around them using the ultrasonic sensors. If the other supported sensors are added it can do many hobby oriented tasks.
Using a
The Rover 5 platform is relatively inexpensive and has great motors with integrated wheel encoders. The whole system is programmed through RobotBASIC communicating … Read more

Dagu Rover 5 motor whistle

I recently bought a Dagu Rover 5 with two motors and encoders (not yet connected).  I'm using a DFRobot Romeo to control it and using the supplied 8-cell battery holder to power it.

.Net Gadgeteer Powered Object Tracking Robot

Over the past few weeks i've been building a robot using the .Net Gadgeteer platform and blogging about it.

The robot is based on a Rover 5 Chassis, with an ir compound eye and pan and tilt kit for object tracking.

I didn't find too much information on this site about how to use these awesome dagu products with the .net gadgeteer platform so hopefully my experiences can help to make things a bit easier for someone else.

Doing "something" with my encoder inputs.

I have a Rover 5 with the Dagu red back spider and motor controller. I have connected 2 encoders (one on each side) to the motor controller / red back spider. I found the encoder library, and tested it. I now have 2 working encoders and can read the value of them with the example sketches of the encoder library. So far so good.

There's a science fiction novel I have, (About a robot of course.) Where a secondary character attempts to use some time management software to schedule a minor … Read more

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. 

Houston--Concepts for a young machine

I've been planning, shopping, ordering parts, and waiting for what seems like forever. I want to show you guys what I've been working on, but it's still just a pile of assorted parts while I wait for certain important odds and ends to get it all together. But a couple of weeks ago I put together a sketchup model to get an idea of some sizing and fit and finish. Since I couldn't upload the model, instead I offer a few screenshots of what I've been working on.

IOIO-SHR version 2 sneak preview

Started this weekend with the 2nd version of my IOIO-SHR (Start Here Robot). Because Santa brought me a Rover 5 chassis on christmas, this would become the chassis for it. I got the 2WD version including wheel encoders and the motor controller board.

Here are some shots from the assembly test.

The IOIO is mounted on a carrier board with 3 pin headers for all IOs. Some Jumpers are available to select the supply voltage for the IO headers, 3.3V, 5V from the IOIO or external servo voltage.

RF shielding

The encoder wires on my Rover 5 seem a little short.  The ground wire seems to be a shield around the other three conductors.  Also, I notice that the pin groupings on my 4 channel motor controller have a ground.  Makes me think a little.

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.

Fairly new to this and need some guidance with Rover 5, Arduino Uno, Dagu 4 channel motor controller and SRF-05

Hi all,

 

fairly new to all this; have managed to build a basic obstacle avoidance robot with some guidance from luckylarry.co.uk. Now looking to use the Rover 5 platform and my arduino uno, however I don't know where to start with the control. In the past I have used SN754410 H-bridge chips but this time I've invested in the Dagu 4 channel controller.

Update April 1st   Well the dust has cleared and I have finished and submitted my Google Science Fair project and I very happy with it.  I have added the site … Read more

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
So with Help From Various people including Oddbot and Chris the Carpenter i have a working Rover 5 Base and i can now control it with my IR Controller. It was a … Read more

Rover 5 - 4 Channel Motor Controller: PWM Frequency

I just got hold of OddBot's Rover 5 platform and the 4-Channel Motor Controller.  I'm still fairly new to all this and I'm not sure what PWM frequency to use for the controller.  The datasheet that I have doesn't specify so I'd appreciate any advice you can give me.

Many thanks.

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.
