What is Rokkorlab
Rokkorlab is a not-for-profit 3rd sector association for development of photographic and other fine mechanical products and services. A new product or service is first invented and proposed. If there was demand for the product, resources could be pooled to develop prototypes. Finished products could be manufactured on demand and made available to contributing developers. Suitable products could become available for buyers.
3rd sector means independent - the association is not tied to a commercial or other entity. Ideas flow freely. Several technology platforms are in development for prototyping and manufacturing
Are you a developer
Developers often struggle to find the necessary support to create entirely new or improved products. First there must exist an idea. But what then? How to begin to push the idea into a real useful item? This is where a developers' association could enter the picture.
