11. 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

15. Selection Matrix

16. 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

17. 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.
