1. Autonomous
Inspection
System for
Fences & Drains

2. HELLO!
I am Darren Koh
▸ Singapore University of Technology & Design
▸ Engineering Product Development
▸ Internship: 2nd May – 26th August
Learning Objectives
• Gain experience and knowledge of project management
• Strengthen the ability to develop new design concepts

3. Mission
Statement
To improve the productivity in
maintenance operations, it is
required to develop a new
maintenance inspection
strategy that can effectively
manage the facilities
accordingly
Approach
To develop a prototype to
automate the maintenance
inspection system of the
airport fence and fence lines
and other related
applications can utilize the
resources for subsequent
maintenance operations
Strategy
To use technology to
support the maintenance
operations

Monorail Trolley

5. Drones
Key benefits
▸ Innovative
▸ Fast
Disadvantages
▸ No flying within 5km of
the airport
▸ Battery constraint –
short flight time (~ 30
min)
▸ Weather dependent

6. Static Camera
Key benefits
▸ Easy
implementation
▸ No risk of being
FOD
Disadvantages
▸ Small coverage
area

7. Autonomous Monorail Trolley
Key benefits
▸ Can run 24/7
▸ First responder to a
security breach
▸ No risk of being
FOD
Disadvantages
▸ Limited to fences
only
▸ Extra load on the
fence
▸ Might interfere with
existing security
system

10. Autonomous
Ground Vehicle
▸ Customizable: autonomous,
remote controlled, live video-
feed
▸ Flexibility: with a little
modification, we might be able to
use it for drain inspection
▸ Weatherproof
▸ All-terrain
▸ Long battery life (approx 3
hrs)

11. Development Stages
Current Stage
▸ Remote controlled
▸ Tele-Operated
▸ Live stream
▸ App development
Opportunities for
Future Development
▸ Autonomous
driving (RTK GPS)
▸ Manual override
▸ Integrated floating
platform

TIMELINE
* Current progress

13. Benefits of this Project
Current Challenges
• Sourcing for companies
• No existing product in the
market
• If we were to built it in-
house, no single supplier
that supplies all the
components
Market value by Servo
Dynamics: 100k
Build in-house: 50k
• Reduce manpower
• Easier to monitor the
fence
• Better management of
resources
