ROS 2 compatibility with Rosbot 2.0

[jfm]

Hello,

 we have 5 working Rosbot 2.0 robots in the lab, but it seems that one cannot 

readily use ROS 2 with them, so they are currently using a “dead” ROS version (noetic). Is there any
reasonably easy way to run ROS2 (for example, humble) in Rosbot 2.0? If not, would it be possible
to “upgrade” them to the 2R version by changing the main SBC board to Raspberry 4?
It would be quite wasteful to discard all of them just because of the changes in ROS…

Regards

Hello @jfm

The topic has been discussed in other threads. Please check them out and let me know if you have any further questions.

[Closed] ROSbot upgade to Rpi4

Digging further, it appars examining messages on the /_motors_cmd topic is a logical next step. Since ros2 code is using the diffdriver controller from ros2 distro, is seems there is one firmware version.

Can we replace UPBoard with another SBC?

Hi, We have a number of ROSbot2 Pro, and would like to replace UPBoard with an ARM based SBC. I see that ROSbot 2R has RPi 4 SBC. Can we swap the UPboard with RPi 4? Do we need to replace firmware on the Core2 as well? Secondly, can we use another more powerful SBC such as Rockpi 4C+? Thank you for your guidance. Best regards, Jon.

[Solved] I want to upgrade the rosbot2.0

I am using rosbot2.0. I’m trying to switch from Tinkerboard to Nvidia’s NX or AGX. In the case of NX, there is a version that uses an SSD card and a version that uses an SD card. In the case of AGX, there is a version that uses an SSD card. Can i control the rosbot with NX and AGX with the image on your homepage?

Best regards

I am in a similar situation and I would like not to upgrade the hardware, but at least get to ROS2. I know that before there was this tutorial with foxy

ROS2 Demo for ROSbot 2.0 | Husarion

that was also for the ROSBot 2.0 with the tinkerboard. However, going to the download page, the instructions point only to noetic. Is it possible to have the latest working image that has ROS2 for the tinkerboard?

Thanks!

The article redirects to the download section, where only the Noetic image for ROSbot 2.0 is available (there is no ROS2 image on thinkerboard). I suggest you check the above articles. From my side I will add that Foxy also uses Ubuntu 20.04, you can try to install ros2 on it. Or use ros bridge and develop inside Docker conftainer.
