Objectives
- This open-source electromagnetic tracker project aims to teach and develop open-source electromagnetic trackers, to enable extending performance in directions that existing proprietary trackers do not address.
- This project aims, in part, to develop methods of accurately characterizing transmitter and receiver coils without the use of costly precision robots.
Approach, Plan
- Over the past year, Peter has developed and tested a simple and fast buffer design between the steady-streaming ADC data and the bursty USB interface. This fast interface replaces two-years-ago's very-slow USB interface in Pete's prototype three-transmitter-coil three-receiver-coil hardware.
- With the electronics now understood, Peter's attention is returning to the problem of accurately characterizing coils. Understanding of how the electromagnetics behaves, permits design of simpler and better characterization protocols than naive protocols that just try to optimize position and orientation accuracy.
