The individual emitter PCB coils are set in precisely known locations within the coil housing. These locations are used to generate the magnetic field model for the Anser system. The housing is fabricated from two metal-free polycarbonate halves containing precisely machined square recesses which match the dimensions of the PCB coils. Full schematics for the coil housing can be found in the Anser project repository. A quick overview of the housing layout is shown below.
The locations of the emitter coils within the recesses of the bottom half of the housing. Cable routing to each coil is also shown. Full solidworks schematics for the coil holder are available in the project repository. The 4 inner mounting holes are used to secure the Duplo baseplate for the purpose of calibration and testing.
