In terms of news letters, besides the Robot Report, there is also https://www.weeklyrobotics.com/ and recently this guy has been advertising his newsletter on HN a lot (which also seems decent but I haven't followed it in detail): https://thegraspnewsletter.substack.com
Kat's weekly news on ROS Discourse are really well curated, too, I think: https://discourse.ros.org/t/ros-news-for-the-week-of-june-17...
