Baiduspider is the generic name for Baidu's official web crawler. Baiduspider is the general name for three different types of crawlers: a desktop crawler that simulates a user on a desktop, a mobile crawler that simulates a user on a mobile device, and a mini-program crawler that simulates a user within the Baidu mobile app.
Your website will probably be crawled by both Baiduspider Desktop and Baiduspider Mobile, and your mini-program will be crawled by Baiduspider Mini-Program. You can identify the subtype of Baiduspider by looking at the user agent string in the request. However, all crawler types obey the same product token (user agent token) in robots.txt. That means any directive set for Baiduspider will take effect for all types of Baiduspider, so you cannot selectively target either Baiduspider Smartphone or Baiduspider Desktop using robots.txt.
