Fractal robots use electricity for power to move and to communicate between themselves.
The power routing distribution system built into cubes can carry hydraulic and pneumatic sources of power as well. Thus typical tools found in the factory floor can be integrated into one machine using fractal robots. Instead of attaching to external tools, the cubes can fabricated with the tools inside them. This is called fractal tooling and is covered elsewhere. With fractal tooling, any machine can be assembled with great ease.
