5. The visual inspection module of claim 1 , wherein a first arm of the pair of arms is axially offset from a second arm of the pair of arms relative to the inspection unit and the module housing, creating a parallelogram configuration in which rotation of one of the first arm or the second arm causes the other of the first arm or the second arm to follow while remaining parallel thereto, thereby maintaining the inspection unit substantially parallel to the first and second surfaces.

6. A visual inspection module for a robot, the visual inspection module comprising:

a module housing;

a mounting interface coupled to the module housing for mounting the module housing to a body frame of the robot;
