Stack Exchange — robotics.stackexchange.com
The content of robotics.stackexchange.com (https://robotics.stackexchange.com/), a Stack Exchange question-and-answer site, as published in the Stack Exchange Data Dump of April 2024 on the Internet Archive. The posts table holds 124,988 rows: 98,860 posts (45,274 questions, 53,148 answers, 215 tag wiki excerpts, 215 tag wikis, 4 posts of type 6 and 4 posts of type 7) and 26,128 comments, written between 13 February 2011 and 31 March 2024. Beside it are 29,795 user accounts, 80,631 votes, 33,961 badges awarded, 1,297 tags, 294,225 post revisions and 1,016 links between posts. Every answer keeps the question it answers and every comment the post it was written on, so the threads can be rebuilt. The Internet Archive item describes the dump as anonymised; the votes table names the voter in only 60 rows.
