FAQ

: Communities for robotics enthusiasts, engineers, and educators covering hardware builds, automation, and research. Discord hosts maker communities for Arduino and Raspberry Pi projects, while professional and academic organizations serve more specialized robotics practitioners and researchers.
: Hive Index lists 10 Robotics subreddits on Reddit. Most listings with size data are massive (50%) or huge (30%). We only have a handful of listings so far, so treat these numbers as directional. The main Robotics topic page covers every platform we track for this topic.
: Forum is the most common feature (100% of listings).
: All 10 listings on this page are free to join (no paid membership or application gate listed). Access rules can still change on the community side.
: On Hive Index, the default Popular sort surfaces r/robotics, r/drones, r/UAV, and r/FRC first. Popularity reflects visitor interest in communities on the site, not a universal quality score. Use the sort menu for Ratings, Largest, or Newest.
: Listings are submitted by community builders and researchers, reviewed for topic relevance, and updated with platform, feature, member, review, and traffic data where available. Member counts are approximate. Popular reflects visitor interest in communities on the site, with richer profiles breaking ties. Ratings, Largest, and Newest use review scores, reported member counts, and listing age instead.
