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.

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

Project Idea #4 Remote Controlled Vehicle 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

Selection Matrix

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.
