Optical Engineers (lens dimension, material & finish specification), Industrial Designers
(incorporating aesthetics & human factors), Manufacturing Engineers (designing for the best
processes appropriate to our expected volume levels), QA Engineers (designing test plans for
them), Compliance Engineers (getting UL & CE rule clarifications), Marketing & Project Managers
(requirements & scheduling).
 Adapted quickly to frequent requirement changes. Pushed back on changes where appropriate
(always constructively and respectfully, sometimes passionately); still did what I was asked to do.
Helped identify inadequately specified requirements and suggest better ones.
 Worked in SolidWorks and EPDM, as well as ARENA web-based BOM management.
2/2010 to 11/2010 Misc. Contract Work Manchester, NH / Shanghai, China
 Designed enclosures in SolidWorks and Pro/E for Helix Design in Manchester, NH.
 Provided Segway with onsite technical support for the 2010 Shanghai World Expo. Covered
subsystems I helped design the year before (see below) as well as other subsystems. Guided
local technicians in maintaining a dozen prototype vehicles that drove autonomously for 4,000
performances in front of a live audience.

 Led the design, fabrication, and mechanical integration of a two-axis robotically-balanced
concept-level vehicle in 3 weeks with two other engineers and several technicians.
 Led the mechanical design of the “sliding chassis” for a development-level vehicle; this sub-
system houses batteries & charging electronics while securing the 3 other major sub-systems (a
two-person “coach”, a lower “fixed chassis” that moves relative to the “coach” & “sliding chassis”,
and a “slide actuator system”) to each other.
 Designed the development-level nose-wheel landing system, which includes a mechanically
driven (and force-limited) hydraulic brake actuator, redundant wheel-touch sensors with EMI
shielding, and catastrophic energy absorption. Interfaced with off-site coach designers, who
placed tight space-constraints on the system.
 Led the first mechanical integration of the full system (i.e. the Segway powerbase that drives the
GM EN-V concept vehicles):
 Planned and implemented the two-week build schedule for the first machine,
 Learned how to assemble each subsystem from its respective engineer,
 Documented assembly issues, worked around them, organized rework,
 Managed the check-out and hand-over to the embedded systems team (and associated
paperwork),
 Led technicians in assembling 3 more machines, and
 Used photos and a wiki to write detailed work instructions that documented the assembly
process and let us hand subsequent builds completely over to technicians.
 Worked in Pro/E Wildfire 4 and Windchill, as well as ARENA web-based BOM management.

9/2006-Present FIRST Robotics Teams 1512, 2342 Concord & Nashua NH
 Mentored FIRST Robotics Team 1512 “Metal Vidsters” for 5 seasons
 Mentoring Team 2342 “Phoenix” for 6th season; primary SolidWorks mentor all 6 years.
 4
th
season as Lead Mechanical Engineering Mentor; currently invest 500+ hours per year.
 I help students learn to think like R&D engineers. I demonstrate techniques and ask questions
that build on their current abilities. I keep tabs on the robot’s development and help our student-
leaders identify and stay focused on the critical path. I push for simplicity, iterative design, and
extensive testing. Together we build a 150 lb robot in 45 days.
 Nominated twice (2014 and 2015) by the students for the Woodie Flowers Award for “clearly
explaining mathematical, scientific, and engineering concepts”.
 In 2015, my team made it to the World Championship in St. Louis and performed well enough to
be an alliance captain in the Archimedes Division playoffs.
