In this new thread, we can discuss any doubt or problem found when installing or using the ROS package qbo_control, that you can find in the following link: https://github.com/carlosjdd/qbo_control

If you are starting to control Qbo with ROS, please have a look to the thread "How to control Qbo using ROS". Hope the indications shown there and in the README file of the ROS package are useful.

How to control Qbo using ROS

caju — Wed, 14 Oct 2020 06:52:23 +0000

Hello!

I have managed to control Qbo using ROS and I want to use this topic to explain how to do it. First of all, you must have an operational version of Qbo. You can use the original raspbian image or you can start from zero (I recommend this option, although you may have some problems to install and have everything working.) You can use the attached installing file provided by @chrisbuy ("QBO_Installer_09.sh").

To install it, you must use the following, or older, Raspbian image:

http://downloads.raspberrypi.org/raspbian/images/raspbian-2019-04-09/

To check that the serial configuration works properly, you can execute the attached file "test.py" placed in the same folder than the file "QboCmd.py". The next should happen:

- Nose switched on in blue color

- X motor moves (right - left)

- Y motor moves (up - down)

- Smile in the mouth

- Center head

- Switch off nose

- Switch off mouth

Once you have checked that everything is working, you must install ROS and use the next ROS package that I have created:

You can find all the steps needed in the README file.

Hope this brief tutorial is useful and you can manage to control the robot using ROS.

Configure Raspberry to control serial ports

Hi everyone!!

I have a Qbo and I would like to start a new raspbian image from zero to include ROS and several ROS packages that I have already developed. To do that, I do not want to install all the Qbo software, but I want to control every actuator and sensor.

I would like to know how to configure the raspberry Pi to use the speaker, the microphone and the serial outputs and inputs to control the motors, the mouth and nose leds and the touch sensors.

I have tried to have a look at the Installing_Qbo.sh orders and have tried to execute those that I thought could have helped me to control everything using the library QboCmd.py. But I have not succeeded.

With the cameras I have no problem because they are directly connected to the Raspberry.

If anyone could help me I would be very grateful, because I do not want to use the Qbo original code, but make a new system integrated with ROS, but to do that I need to control all the actuators and sensors of the robot.
