Johnson: Sans serif font, course name, raise title to boost contrast Flexible Manufacturing with a Robotic Arm and Lego’s ELM 4701 ELM Project I Fall 2002
Background • What is flexible manufacturing? • Automatic Product Switching • Rapid Introduction of new product • History of the RM-501 Johnson: Shortened title. Purple bullets. Rapid introduction of new product is an aspect of FMS that you folks have paid more respect to than I have, so, even though it’s not part of your problem statement now, you can use this opportunity to forshadow later bragging about programming interface and versatile part handling (I.e. hoppers with no side walls). If you’re really feeling cocky, revise your problem statement and we’ll add some very rudimentry new ‘product’ (two parts?) to the demo. Alex Rust, Jon Turgeon, Mark Jarrett
Problem Develop a system that flexibly manufactures at least two products. • Use existing robotic arm. • Assemble two electromechanical Lego products Johnson: Title shortened. My original prob statement was redundant. Automation is presumable in an FMS. Consider dropping periods, but at least be consistent. Bullet color. Jon Turgeon, Alex Rust, Joe Eastman, Mark Jarrett
Johnson: Good sequence choice Lego Products • Child’s night light with thermo protection • Light activated cooling fan Nate Lamie, Matt Nusbaum, Will Fisher
Johnson: Dart photos. Consider a standard iso like point of view. See below. Child’s Night Light Will Fisher, Nate Lamie

Johnson: ‘versatile hoppers’? Solutions • Keypad for user interface • HC11 interface to robot controller • Gripper modification • Circular array of hoppers Will Fisher,Joe Eastman, Alex Rust, Mark Jarrett
Johnson: Some good improvements. You’re half-way there. First, you’re killing me over the concentric business. You’ve already argued effectively in your status report that the arm should rotate at the CENTER of two concentric regions, so show it that way. And, if you’re only using a range from 9 to 3 o’ clock, then show it that way. LCA abbreviation is too complicated- kill it. See word art below. Everything should be larger - especially fonts and drop the serifs. Sort of ironic that your keypad label is placed within a box that pictorially represents a display right?. Perhaps you mean Keypad/Display? Haven’t you decided to mount the system on a cart? That should be labeled. This slide should be preceded by an appearance slide (either a photo of a mock-up as in the status report or build on the fine 3D model you’ve got -thanks to Alex?)
