MEASURE PHASE
October 27th - December 8th
The Measure Phase is the second step in the DMADV Six Sigma process. This step entails measuring all base line characteristics to compare the improved processes to. This step also involves a significant amount of computer aided models to perform an analysis on our AGVs capacities.

AGV Design and Creation
Note* due to the time constraints of purchasing parts of and nature of the project, the design of the AGV must take place earlier in the process outside the Design Phase. The completion of the next four phases has content out of the Six Sigma DMADV process order but each section implements tools from each phase.
Once the team had defined engineering requirements and critical to quality characteristics the team was able to sit down and draft iterations of the AGV in order to best fit what the customer was looking for. The team decided on an AGV with a square build platform to both mount the DeXter to and to Print on as well as a four wheel configuration seen in the graphic below.
The surface of the AGV is the perfect size to hold one DeXter unit and the AGV's floor footprint is a tessellated shape meaning that there are many different configurations and arrangements where the shapes can fit together in a square grid pattern with out negative space. This shape allows for multiple AGVs to configure themselves in close proximity and also is a very simple geometric shape to allow for spacial configuration in mapping and tracking programs. The design was then created in Solid Works and is easily able to be manufactured using machines accessible at the FAMU-FSU High Performance Materials Institute. The parts list and appropriate purchase order were also filled out during the Define and Measure phase to ensure ample time for manufacturing and testing.
The AGV Chassis featured above is constructed out of wood and extruded aluminium and was produced as a prototype for a Northrop Grumman representative in junction with a presentation on the progress of the project.
