Title
of activity- Do some research and what need to be
attached at the project
Objective-
got overview of the project by looking video for research and leaned what
circuit should be constructed.
Content-these are some
research and idea for my project

need to be used)
Results
and analysis
-Problem
encounter
1.If
I use infra red (IR) as transmitter and receiver for optical encoder for more narrow
light. In theory, these will allow me to increase the resolution of optical encoder
by increasing the number of slots. Thus,
it will reduce the steady state error .Besides, time for getting data and for controller
to take action also can be reduced. So,
the motor speed response will become better. So, we need to try weather it is
function or not.
2.
Due to the size of photodiode which is quite big, the number of slots at
cardboard that can be used is 8. The rotary encoder also have a less durability
to do a constant test, because it easy to broke.
Conclusion
I have detected some problem
in sensor and I choose optical encoder because it produce pulse and it is easier to compare
to lab view or PIC.
