Lab induction
Information on OH&S is in your lab manual, and the demonstrators will
give you a refresher in the first lab.
To be able to submit assignments in Moodle, you need to correctly
complete the Lab Induction Quiz – score full marks.
If you do not complete this step, you will score zero for your lab reports.

Steps for asking questions
Jonathan Li 2/2010
Follow these steps if you have a question about TRC3500
Step 1: Try to find a solution yourself
Look at lecture notes, textbook, unit guide etc
Have a few tries at the problem
Step 2a: Ask lab demonstrator
Step 2b: Discussion boards on MUSO
Don’t be shy!
Step 3: Ask lecturer
Can e-mail questions or consultation requests
Include “TRC3500:” in subject field

Microwave Ovens Contain Sensors
Most modern white
goods are
microprocessor
controlled and
contain sensors to
improve their
performance

Robots
Even simple
swarm robots that
emulate insects
contain many
sensors

Capsule Endoscopy
There are some sensory
devices that you may not
be familiar with.
This is a miniature
camera that is swallowed
and takes one picture per
second as it passes
through your
gastrointestinal tract. It is
used to diagnose
intestinal problems.

Industrial Processes
Most industrial
processes and
production lines
are computer
controlled and
rely very heavily
on sensors to
monitor the
quantities that
need to be
controlled.
