Bluetooth Connectivity

We haven't accomplished yet connectivity between Player and Nero but we already accomplished connectivity using the Terminal so I will explain what is to be done in order to achieve it.

1. $cd /etc/bluetooth
2. $ls
3. Make sure you have the rfcomm.conf file and then $sudo gedit rfcomm.conf
4. In the file paste:
rfcomm0{
bind yes;
device 00:0A:3A:2D:7C:64;
channel 1;
comment "Serial Bluetooth";
}
5. The interface should then be created, to check it type $ls /dev/rfcomm0 and it should appear. That is the new interface to be used.
6. To connect to the AirCable use $rfcomm connect 0
7. A connection message should appear and the blue led in the AirCable should be turned on.

We now need to know if we can execute a script of something to connect Player and Nero but we are making progress.

Cheers!

Aria Demo using the Pioneers

Since the beginning of the week we've been trying to change the way we will use both Pio and Nero in order to finally start to work on them physically. As teacher Alejandro Pineda suggested, we should get rid of the on board computer the robots have and just focus on managing the data they get and receive via serial port.

To achieve that we've been making tests on the printed circuits and we now found out the way to make them work without the computer and just by serial port which will be more convenient because we can get a Bluetooth adapter to get wireless communication between our computers and the robots.

First we had to install the USB-Serial cable and we found a website which explains how to do it in a quick way: http://blog.mypapit.net/2008/05/how-to-use-usb-serial-port-converter-in-ubuntu.html

Using the Synaptic Package Manager one can install the Aria libraries and then use the example programs to test connectivity, the directory is /usr/local/Aria and there is a directory with examples called 'examples'. We used the demo provided and the syntax after the cable has been installed is: $ ./demo -robotPort /dev/ttyUSB0

We executed this demo program and it worked fine, the sonars seems to be working properly but there are several tests to make. For the time being Nero is now operational. We will continue doing a couple of tests and then use playerjoy to teleoperate Nero. After that we will procede with Pio in order to get him fully operational too and make the proper tests.

Phone meeting between DFKI and CEM

Today people from DFKI and from CEM at directive positions had a phone call to stablish the ground for student visiting both institutes.

More details to follow.

Work on Friday

Just like Luis just say, we go to the lab on Friday, and we try to fix the usb problem, but the time wasn't enough. Another thing that happen on Friday is that I take the "ide to usb" cable to try to get the image of the disk in a low way... I'm still with this problem, but I think is possible to get the image and we can put on any HD to make it simple(OS installation in NERO). We will find a solution for this problem soon...

Cheers :)

New tickets

I've created new tickets in Assembla for all of you. Please see them and close those you have finished.

Problems in the Nero's OS

Hi,

Yesterday I try to install Ubuntu in "Nero". But I have one "little" problem I can't connect the CD player because I don't have the AC cable. So, if anyone have "one" haha :) Can he/she lend me for the "cause"? haha :) And with this I hope we can know what is the problem... the HD or anything else ...

Cheers,

Carlos L

In the other hand, I was thinking in the OS we will install, and I think the best option is the same Ubuntu OS that "Pio" have. Maybe Carlos G, Laura and Arturo can say me what Ubuntu "Distro" is, to find and download it.

URGENT!!!!!!

Teacher Marissa we need the bus for the HD which is in the locker at Visión Artificial Lab, is the only thing we need to finally finish assembling the interior robot but we can't because it's locked up.

Great news!

Hi everyone!

Today Jean, David and I went to the lab to try to assemble the interiors robot and we almost succeded. Everything in the inside of it is almost connected, we just need the bus for the HD so we can connect it to the motherboard and to take away the laser from the rescue robot so we can finish assembling the interiors robot. When we get the bus for the HD we will start making test to verify that connections were made successfully. We hope on monday teacher Marissa will provide us with the bus and make everything we need to start "playing/staging". Have a nice weekend!

Player/Stage

Hi everyone!

I just successfully installed Player (I think...) but to install Stage requires a lot of other programs and libraries which I was trying to install but somehow I wasn't able to do so because it said at the output that there were some errors and nothing about them so I didn't know what to do. Hope someone can make a quick guide to install Stage and some troubleshooting for us that don't know a lot about Ubuntu.

In other news, we checked the USB port and the cabling is right so perhaps someone can tell how to bring up the port in Ubuntu, I guess that's the problem about the USB.

Good things to all!

Robots

Hi everyone!


Sorry for not posting sooner! Today Jean and I tried to debug why the USB port in the laser of the Pioneer is not working, in the electronics part it's working just fine so perhaps there's a problem with Ubuntu where we have to turn it on or something like that which I don't know how to do it, perhaps Luis or Carlos could help us with that part. On the other hand, the interiors robot got to us when we were leaving so we didn't check it out until tomorrow. I don't know ifLaura and Arturo made some advance but if not I certainly hope we can do now that we know a little more about how the other one works.

Today while we were checking if the USB could work we thought about updating Ubuntu but perhaps it's wiser to wait to make the image of what we have on the Pioneer's HD and then update and see what happens, perhaps the problem with the USB can be fixed that way. Any suggestions about that?

We'll keep in touch!

Progress and notes for tasks.

I've just posted the task instructions or notes for the task that are runnning since the project started.

The following is an image of the tasks that must be finished soon. You can see the progress and the name of each task.

Notice that we are behind schedule. Please try to catch up.

All the best,
