Special Programs Presentation
• Nano-Satellite Program
• Exploring Frugal Engineering in India
• Living Lab in the Communities
Nano-Satellite Program
• Nano-sats are small satellites with a mass below 10kg
• Designed with some propulsion system on-board, attitude control,
communications & computational system, power systems and
payloads
• Challenge to design because the space environment is harsh
• Excitement is to see the launch of the satellite that you designed
• Road to launch is interesting and fraud with challenges but they are
real engineering tasks
Slide 2
• Educational program with research components
• Collaborators are DSO, SSTA, EDB, DSTA + NASA (hopefully)
• In the longer run, the program will include student exchange to
some Universities with well established satellite programs,
internships overseas, competitions and conferences
Why a satellite program at NUS?
• Satellites offer rich opportunities for integration of technologies
across various sub-disciplines in EE
• Also a natural cross-disciplinary platform for EE and ME students to
work together
• There are real design issues to be solved – train engineers to design
for other complex engineering systems, not just satellites

Summary of who are eligible
Year 1 Students – Join as DCC students
Year 2 Students – Recruitment starts only in sem 2 AY2011/12
Year 3 Students – Recruiting now for EE2001 in sem 2 AY2011/12
Special module A : initial design experience on building a balloon-based
system (build and fly a balloon based system and experience the
challenge)
Special modules B & C : physics of satellite orbits, introduction to
subsystems in a satellite, read in Year 2 for DCC students
Slide 5
Exploring Frugal Engineering in India
• Frugal Engineering (FE) is a philosophical approach to designing
products for customers with very low purchasing power
(BOP/MOP)
• Not about stripping away features to reduce cost but it is about
complete re-design and innovations in a product which will
benefit a large segment of the community
• Practice of FE encourages critical thinking required to
conceptualized products which maximizes value to its customers
• In order to be successful frugal engineers, it is impt that you
engage with the communities who will be the target users of the
product that you are going to design
Slide 6
When is the field trip to India?
Program duration : 5 – 30 December 2011
First week : 5 – 9 December (attend workshop in Singapore)
Next 3 weeks : 10 – 30 December (time spent in India)
Place : Outside Mumbai, India (all expense paid trip)
Students register for a 2MC module (EE3030A) for the field trip
Who are eligible to apply?
Year 2 Students – Reading EE3031 in sem 2 AY2011/12
Year 3 Students – Reading EE2001 in sem 2 AY2011/12
Return to NUS to prototype or to carry our further studies on your ideas
Slide 7
Living Labs in Communities in Singapore
• Students spend 3 to 4 weeks in the Singapore General Hospital
• Idea is similar to the FE trip to India
• Students attached to the Rehabilitation Centre in SGH
• Work with doctors and therapists to understand part of their work
• Engage with patients to observe how they interact with equipment,
assess the functionalities of existing equipment, understand patients’
experience when working on the equipment, etc
• Conceptualize or re-design equipment which are better than the
existing ones
Slide 8
When is the attachment at SGH?
Program duration : During the December holidays and possibly extending
into 2012 (depends on how students are scheduled)
Program Details : A schedule will be drawn up for the attachment at the
SGH Rehabilitation Centre
Students register for a 2MC module (EE3030B)
Who are eligible to apply?
Year 2 Students – Reading EE3031 in sem 2 AY2011/12
Year 3 Students – Reading EE2001 in sem 2 AY2011/12
Students expected to prototype their designs or carry out further
investigation on their ideas
Slide 9
How to Apply for these Programs?
• Will send out an application form after this
• Submit application by 21 October 2011
• May call for interviews and decision to be made by early November
Welcome Mechanical Engineering students to apply as well.
