rosbot-docker

Docker Image for ROS Melodic Node providing interface for STM32 firmware over ROS-serial.

rosbot-docker contain following ROS packages:

With docker-compose configuration shown in demo it can communicate with hardware of both Rosbot 2.0 and Rosbot 2.0 Pro.

Flashing the firmware | switch kinematics

Firmware if flashed from inside of the container. In order to use specific kinematics flash matching firmware.

Differential kinematics (normal wheels)

docker run --rm -it --privileged \
husarion/rosbot:noetic \
/flash-firmware.py /root/firmware_diff.bin

Mecanum kinematics

docker run --rm -it --privileged \
husarion/rosbot:noetic \
/flash-firmware.py /root/firmware_mecanum.bin

Building locally

docker buildx build \
--platform linux/amd64 \
-t rosbot-docker-test \
.
