If you also had an Arduino to use with the shield then yes this should be possible. The code that we supply would need to be modified, which depending on your experience may take a while, but it would definitely be a learning experience.

It it possible?

Thanks for your question. This robot, and the software we’ve created for it works fully with the Raspberry Pi 2. The initial photos show the old Model B Pi, but you should also see that there are photos showing the B+, and this configuration will also work with the Pi 2. Any problems getting up and running, please let me know.

I am interested to make this robot
I am going to use Raspberry PI 2. Is it compatible with the modules and works perfectly with your tutorial?
Because it seems you are using Raspberry B

Thank you

Sorry for the delayed reply. To get our software to work with the Redbot, you’ll need to write a sketch for the onboard Arduino (can probably modify the one we’ve written for the mini driver) and a Python class to handle communications between the Pi and the Redbot board.

This forum post is fairly long and rambling, but should hopefully give you a good idea about the structure of the software. The Arduino sketch needs to listen for commands coming over the serial connection and use them to set motor speeds etc. The MiniDriver Python class we have basically provides an interface for controlling the robot’s hardware and sends serial commands to the Mini Driver Arduino board.

The full MiniDriver class we’ve written is fairly complicated and does things like automatically uploading the correct Arduino sketch if the one on the Arduino is out of date. You probably don’t want to go to all that trouble. Instead I would recommend that you focus on implementing the setOutputs routine on your Python RedBot class which sets the motors speeds and the angle for the neck servos. If you don’t have neck servos then you can ignore those angles and instead just focus on passing the motor speeds down to the Redbot board. Once you have your RedBot class working, you can then use it to replace the MiniDriver class in robot_controller.py.

Hope that all makes sense. Interested to hear how you get on.

Could I ask for a little help on where I should make the changes in the python scripts? I’m very green to all this and there are so many scripts.

Don’t suppose there is a redbot version of the software?

Thank you.

Thanks for the question. The Pi Co-op is Arduino compatible, like the Mini Driver, so it can be used as part of a robot that uses the same software as this one. However, it lacks a motor driver, so you’d need to add one on, such as the L293D in order to be able to move DC motors.

Is it possible to use Pi co-op here instead of Dagu mini driver?
What change needed in raspi?

BTW, good tutorial!
