A self-reconfigurable robot module and self-reconfigurable robot is provided, which belongs to technical field of robots. Self-reconfigurable robot module comprises rolling shell, magnet and driving mechanism. Magnet locates in and magnetically connected with rolling shell. Driving mechanism locates in rolling shell, magnet connects to driving mechanism, driving mechanism abuts against inner wall of rolling shell through attraction force, used for driving magnet to move along inner wall of rolling shell and changing gravity center of self-reconfigurable robot module. When driving mechanism drives magnet to move along inner wall of rolling shell, position of magnet relative to rolling shell is changed, so positions of connecting points, used for being connected with other self-reconfigurable robot modules, on rolling shell are changed, multiple positions on surface of rolling shell can serve as connecting points, self-reconfigurable robot modules are connected without aligning specific connectors, connecting time is short, efficiency is high.
