P a g e 3

• Maintained and extended software for a vacuum robot for use in semiconductor manufacturing.

• Took responsibility for the layer between high-level commands and low-level control API, including trajectory planning, low-level device configuration, event handling, error reporting/logging, and data gathering.

• Implemented methods to correlate sensor events (laser beam covering/uncovering) with timestamps and joint angles, propagate the sensor event information across the unmanaged/managed boundary to the supervisory layer of the software, and transform the sensor event information into positional values indicating the error offset of a wafer center from its assumed position.

• Extended the code to a new dual-arm robot configuration. This required extensive modification to the entire library.
