Abstract: The disclosed technology provides solutions for generating three-dimensional maps for use by autonomous vehicles. A system of the disclosed technology may utilize a sensor assembly for supporting a plurality of sensors that is configured to be removably coupled to a roof of a vehicle, a server rack assembly that is configured to be removably coupled within a trunk of the vehicle, an encoder assembly that is configured to be removably coupled to a wheel of the vehicle, and a user interface that is configured to be removably coupled to a dash of the vehicle. The sensor assembly utilizes an integrally formed tubular member for supporting the plurality of sensors such that the sensors are fixed at precise predetermined distances from each other regardless of the type of vehicle used for generating the three-dimensional maps.
