An apparatus and method for winding electrical coils (electromagnets) is described. A self-propelled and self-referencing winding vehicle uses features on a winding bobbin to guide the direction and/or orientation of the vehicle, while laying electrical conductor material (e.g., high-temperature superconducting (HTS) tapes) as it traverses the bobbin. The vehicle may wind electrical coils with complex shapes. In some embodiments, the self-propelled, self-referencing (SPSR) vehicle may perform other magnet fabrication and assembly procedures.
