I'm confused with how to control my rover 5

Hi all,

I have a few questions, which may be a bit stupid but I am new to robotics.

I have a picaxe 28 pin project board, a rover 5 4WD robot platform with encoders, a parallax ping ultrasonic sensor and a standard servo.

I am planning on making an autonomous robot like that on the start here instructions.

I have found out that my picaxe won't be able to power the rover 5. So I am looking at buying the Dagu 4 channel motor controller. Will I be able to controll the rover 5 4WD and encoders, the servo and ping sensor if I buy this motor controller?

Also, can someone help me in how to wire up the motor controller and picaxe boards? And how do I controll and code it?

And finally; can I supply the robot 5V from one power source and will this be sufficient? Also, what power source do you recommend for this?

Many thanks in advance


Hello Luke

I’m not too familiar with all the parts you mentioned, but I have looked at the Dagu 4 chanel motor controller - it takes a PWM bit and a direction bit - TTL level meaning the Picaxe or almost any micro-controller interface with the motor controller.

Here is a linke to the manual - http://myrobotlab.org/sites/default/files/dagu4MotorController.pdf

As far as 5V for everything - that would depend on the details of your motors, and I don’t remember what a rover 5 takes… but you probably can google it…

Thanks for the reply. I’m

Thanks for the reply. I’m sure I’ll be able to work it out with the help you have given me and the manuals.
