Decision Making



Through much consideration, we decided that
the best approach to decision making for our
group is the majority vote strategy.
If a decision can not be effectively reached by
our group, our TA will be employed to help us
reach a decision
The Prof/Lecturer has the final call on any
team decision

Project Idea #1

Mobile Automated Solar Power



It will provide power to RVs, campers and remote
weather stations. Power will be accessible through
outlets to where equipment i.e. computers can be
connected.
Will contain solar panels with an electrical interface,
and will power up small household appliances.
Project seems to intrigue group members.

Remote Accessed Pet Tender




System will be accessed via the internet and through
this, the owner will be able to monitor pets and also
dispense food and water as needed
AC/DC, internet software, access via internet
Owners will be able to monitor their pets while away
from home and dispense food/water as needed
Considerable interest from group members who are
pet owners

Project Idea #3

Automated Lawn Mower





Mower will cut the loan with no human interference.
The lawn mower and yard will have sensors that will
ensure mower stays within the yard, ending in
cutting the lawn automatically.
DC powered.
It will be a good solution for lawn care during
extreme weather or for people who are unable to
take care of their lawn themselves.
Product already exists in market place


Vehicle will be used in UWM campus open house
exhibitions to promote the engineering department.
Vehicle will have a high power DC motor, controlled
via pulse width modulation.
DC power will be supplied via Pb-Acid batteries.
No identical product exists in the market.
Project is sponsored by UWM up to $1000.00

Project Selection

Overall Selection Process








Our project selection process was conducted as follows
First stage was brainstorming in which team members proposed several project
ideas.
Second stage was drawing the expected block diagrams for each proposal.
Third stage was evaluating each project and assigning them score according to the
provided selection matrix, which lead to our chosen project.
Project was chosen for the following reason:
It is funded, meets the requirements of 1 block per person and it can be prototyped
and demonstrated easily.
The major risks in the project:
Time constraints, possible design challenges

Reason for rejecting other proposals:
Other projects had no external funding and were not a good match for team skills

Project selection was achieved through unanimous decision

Proposed Product
Remote Controlled Vehicle





Proposed project is a remote control car, with remote
controlled lights and turning signals.
Car will be used during University open houses to
promote the engineering department and also for kids
entertainment.
This will be the first UWM owned remote controlled
vehicle.
There is no identical project readily available in the
market.
Project is part of the toy industry.
