On linux platforms python Dobot Magician API library doesn’t work - it crashes.
Filed an issue in cri_dobot repo
Linux native binary file libDobotDll.so.1.0.0 was not updated during last update cycle, see update dates on files.
Or other likely reason for segfault is mentioned in this post
UPDATE
Solved by compiling fresh libDobotDll.so from sources provided in Dobot Demo V2.3-en.rar under magiciandll-master sub archive. It can be downloaded from Dobot Download Center, look for Magician Development protocol. And altered DobotDllType.py according to this post
