U3c-L3 Your job is to use the Engineering Design Process to design a robot that would help you with some task in your life. Examples? CORE TECHNOLOGIES CLASSWORK

Introducing the NEW iRobot ® Roomba ® Vacuum Cleaning Robots! A better way to maintain cleaner floors every day! Meet the new Roomba! The newest iRobot Roombas feature dramatically improved vacuum pickup, brush design, debris and particle filtering, advanced cleaning coverage and navigation plus innovative new scheduling capabilities. U3c-L3

CORE TECHNOLOGIES CLASSWORK Improved cleaning performance Improved navigation Easier to use, maintain and upgrade Voice demonstration Virtual Wall ® Lighthouse™ Amazing pickup Larger filter Won't get stuck Lower maintenance Safe and gentle navigation On-board Scheduling Wireless Command Center Powerful suction and rotating brushes Automatically navigates for best cleaning coverage Cleans under and around furniture, into corners and along wall edges Self-adjusts from carpets to hard floors and back again Automatically avoids stairs, drop-offs and off-limit areas Simple to use— just press the Clean button and Roomba does the rest U3c-L3

PROCESS: This is an individual assignment. Read the “Rosie the Robot” article. Go through the design process steps listed on the back of the article. Complete all steps in your notebook. CORE TECHNOLOGIES CLASSWORK U3c-L3

Identify the task you want your robot to solve. How will you use all 9 core technologies? Quiz tomorrow on the following: Be able to list the 9 core technologies You will be given technological artifacts and be required to identify which core technology corresponds to which artifact and explain. You will also need to be able to sketch a diagram that shows the transfer of energy in an electric car and a gas-powered car. Today’s U3c-L3
