"Eora 3D Scanner" - Development of Powerful Algorithms for iPhone

Introduction: "Eora 3D Scanner" is only example. I use it only for the reference. History: High-Precision 3D Scanner, the world’s first high-precision 3D scanner that is entirely powered by a modern smartphone, including iPhone X. Details for My Project: I am looking for exact the same "Software Solution" but for different application. Only Stepper Motor (currently used in Eora 3D Scanner) is going to be used in my NEW Project. No 3D Scanning Features will be included in my project. No laser. No Camera. Reference: Eora 3D Scanner Hardware is using very simple solution - Bluetooth communication with single Bluetooth Chip and Stepper Motor Controller from Texas Instruments. Most of Algorithms are done in software running from app. The Goal for this Project: to Develop the app Compatible with both Android and iOS, the "New Developed Hardware" will connect to smartphone via latest Bluetooth and "New developed App" will be FREE to download from the iOS App Store and Google Play Store. The Target of this Project: Motorized 3D Robot controlled by simple app. Significant Expertise Required: Powerful Algorithms for the app. Interface Expertise: Connects via Bluetooth. Time-frame for this Project: 10+ months. Payments: Milestone payments only. Weekly micro steps in development. One week+ duration.
