Hi there

I am currently learning ROS and have a BrickPi motor shield which I would like to control in ROS

Are there any good tutorials for controlling a Raspberry Pi Python based motor shield?

I am guessing I need to write a subscriber in Python? Most of the Arduino examples I see use serial.

Hi,

some years agi I tried the BrickPI+RPI for LEGO equipment (motors and sensors).

Check this for a start: https://github.com/mockbot/MockBot/bl...

Good luck
Christian

Thank you, that looks epic. Did you do a model for it to? so you can use it in RVIZ?

No, I've never did it. A small picture only :-) https://x49svr40x172.xdsnet.de/xCloud...

Thank you, I want to be able to use path finding with something I am building https://www.youtube.com/watch?v=ojPM1... I guess, I need to use your script, then model the robot then use rviz to control it

Do you have any tele-op control for your script?

Sure: I using this small web-teleop for all my gadgets :-)

https://github.com/mockbot/MockBot/bl... (rosbridge must be started at you robot before) Nice tool for remote teleop and first person camera view :-)

Whats Rosbridge for? I go and google it :) So when I mean teleop, I mean a way to control the robot via the keyboard etc
