This is medium tech: mecanically precise design (motors, alignment system, etc) and in many countries it is a patent mine field. Namely, you could release as open source the blue print _and_ build process of a nano-metric accurate motor, with a nano-metric laser interferometer alignment system, but I would not be surprised to see many corps coming at you and not the friendly way.
