Dear Husarion!

I am using Rosbot Pro 2.0 with ros2 Foxy.

I have used this image for the robot: Downloads | Husarion - * Ubuntu 20.04 + ROS Foxy + Docker + Husarnet client

I have run the following command: ros2 launch rosbot_description navigation_demo_pro.launch.py
and I have have run in to the following issues:

I have already done the following steps:

  • I have reflashed the CORE2 successfully following this guide: CORE2 - quick start | Husarion
  • I have flashed the STM32 with this firmware: wget -O /home/husarion/firmware.bin https://files.husarion.com/rosbot_firmware/rosbot-2.0-pro-fw-v0.10.0.bin - I used this because the link on the page for the firmware was not working

What else should I try or what do you think the problem is?

Thanks in advance,

Daniel

Hi Eredits_Daniel,

I’m afraid that the firmware version you are using is outdated. This may cause incompatibility with the rosbot_ekf package. Please check if your serial_baudrate looks the same as this one and flash new firmware.

There are two ways to flash the latest firmware version:

  • just run flash_firmware.sh file provided with the Ubuntu 20.04 image on your ROSbot:
cd
./flash_firmware.sh
  • if the above option does not help, try to build the PlatformIO project and flash firmware using stm32loader (github repo with instruction).

Please, let me know about it. If you have any questions/troubles, do not hesitate to ask.

Best regards,
Paweł
