Hi everyone, I'm getting to know ROS with arduino programming, and I'm struggling to run ROS as I complete the first tutorial of Hello world . Roscore seems to work because the terminal begins outputting summary and Nodes but then when I input: rosrun rosserial_python /dev/ttyACM0

Nothing happens, not even an error message. It's like I input a newline. I'm not sure what this means or what it could imply. I know for sure my usb port is located in /dev/ttyACM0 , it's the address located on my Arduino IDE which works.

I'm using Mac to run Virtual Box Ubuntu (latest), and have ROS Kinetic installed along with arduino IDE. I also have catkin workstation installed. This was the setup instructed prior to trying out hello world.

If there's any info needed to solve this, I'll be be happy to answer asap. It hurts I can't do the first tutorial

may you try only this rosrun rosserial_python after uploading sketch into Arduino

I don't think you should receive any Output from the command, if all goes as planned. If you follow the tutorial, you should open a new terminal and call: rostopic echo chatter. This should produce Output. Do you do this?

Thank you guys. Mig, you are right in that for each of these commands, I must open a new terminal. The tutorial only states to open a new terminal once where actually, it must be done for each individual command. Thanks for your help!
