Six spheres.

A robot is composed of four cubes, two cuboids, four cylinders and six spheres. The length of the shortest connecting line between two points on a sphere is the length of an arc passing through these two points between two points of a great circle. This arc length is called the spherical distance between two points. Mathematics is a universal means for human beings to strictly describe and deduce abstract structures and patterns of things.
