1. A position tracking system comprising:
a laser transmitter comprising a laser for emitting a laser beam, a controller controlling the laser, and a motor for rotating the emitted laser beam,
a control tracker comprising a housing, a power supply disposed within the housing that accepts power from a power tool battery pack connected thereto, a controller disposed within the housing, a memory connected to the controller, an inertial measurement unit (IMU) sensor providing information to the controller, a transceiver disposed within the housing, at least two photo diodes disposed on the housing, and a laser assembly for generating a beam to be projected unto a surface,
a layout indicator comprising a housing, a controller disposed within the housing, a memory connected to the controller, an inertial measurement unit (IMU) sensor providing information to the controller, a transceiver disposed within the housing, at least two photo diodes disposed on the housing, and a laser assembly,
a local server in communication with at least one of the laser transmitter, the control tracker and the layout indicator.
