Hi,

I have a duemilanove with a AFMotor shield. I plan to attach the encoder and wheels from a recycle'd roomba. I was able to get the source to build and load with the following changes:

OpenInterface.h:

+#include <HardwareSerial.h>
+#include <Arduino.h>
+#define byte uint8_t

I have not attached the wheels/encoders yet, but I see the following error after starting ROS:

[rosout][ERROR] 2012-05-22 15:08:21,102: Failed to contact device with error: [Error reading from SCI port. No data.]. Please check that the Create is powered on and that the connector is plugged into the Create.
[root][INFO] 2012-05-22 15:08:26,476: sending control opcodes.

Hi,

I haven't done any work on this for a while, and haven't tried with the latest Ardunio IDE, I suspect there may be some changes needed for Arduino v1+.

What version of ROS are your running? Again I'm still running TurtleROS from DiamondBack.

The only thing I had to configure correctly was the FTDI port e.g. /dev/sensors/ftdi_A60078HS

see http://answers.ros.org/question/9097/how-can-i-get-a-unique-device-path-for-my/ for how to get that mapping consistently accross reboots etc.

Hey Andrew,

Thanks for getting back to me. I am using electric and need some of the
functionality it provides. So I think I will try to implement a driver
using rosserial instead.

Thanks Again,

-Kent
