Hi!

Finished my build of the AR4 MK3 in Finland some time ago. Even recoded the time the build took me,

52.5 hours of slow, careful and deliberate work.

Ros2 is working thanks to ycheng @ https://github.com/ycheng517/ar4_ros_driver/

Below's a sample with Chris' software (object recognition) and one with ros 2 collision aware IK.
