Hello, I have bought 5 tbots presently. I have already followed the instructions here. I am running the 1.0.17 firmware version presently and using the latest master branch. I am still receiving this error.

Solved .... had to run: from SBC setup rosrun turtlebot3_bringup create_udev_rules and then in OPENCR setup had to make sure the user was added for ttyACM0 in group dialout

export OPENCR_PORT=/dev/ttyACM0
export OPENCR_MODEL=burger
rm -rf ./opencr_update.tar.bz2
wget https://github.com/ROBOTIS-GIT/OpenCR/raw/develop/arduino/opencr_release/shell_update/opencr_update.tar.bz2 && tar -xvf opencr_update.tar.bz2 && cd ./opencr_update && ./update.sh $OPENCR_PORT $OPENCR_MODEL.opencr && cd ..
