  • Stylized image of three orthogonal coils used in 6-DOF electromagnetic tracker sensor

  • Handmade assembly of three commercial solenoidal coils; each solenoid is 11 millimeters long

Key Investigators

  • Retired: Peter Traneus Anderson
  • BWH: Tina Kapur, Sonia Pujol

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 to develop methods of accurately characterizing transmitter and receiver coils without the use of costly precision robots.

Approach, Plan

Progress

  • 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.
