Summer 2015
Milara Inc.
At Milara I successfully conceptualized and designed a new versatile repeatability test station for all Milara high precision wafer handling robots. The test station allowed all of the tests to be run on one table, saving the company floor space, and a lot of time. The time to switch from running one test to another, or to switch robots was decreased by 50%. I tested robots before shipment and used Matlab to provide visual representations of data acquired from repeatability tests. I regularly presented project info to management and technical personnel. For new parts, I compiled technical drawings and manuals.
At Milara, I designed a testing station for use with all Milara robots. The table was designed to house the largest robot, and to use custom collars to house all smaller robots. These cheap collars could be made to fit any future robots smaller than the table's cutout. The testing station was made to house pre-aligners, wafer cassettes, and other Milara testing and calibration equipment. It was made to be very customizable allowing wafer testing to be done almost anywhere within the robot's reach. There are adjustable arms to hold wafers at custom locations, and movable mounts for machine vision cameras to track repeatibility.
I also supported the engineers at the company in conducting repeatibility testing before shipment, and with data analysis. I used excel to organize testing data. I wrote Matlab code to create 3D plots of the distances between the robot's actual movements and the target movements using data acquired from machine vision cameras and software. The data and plots helped to identify hysteresis in some robot's movements if they were not warmed up properly.
Software Used
Milara's code was used to control and test robots
Used Solidworks to design and make drawings for the new testing station
I used Excel to organize and analyze data
I used Matlab to analyze and create visual representations of data collected during repeatability tests
