Engineering Design Process
Step 1 – Identify the Problem
– Pick a strategy that will yield the most points.
– How do we fulfill the chosen strategy?
Step 2 – Identify Criteria and Constraints
– Functional Requirements:
“The robot can score tubes on pegs.”
– Design Constraints:
Robot must weigh less than 120 lbs…
– See Robot Rules…

Engineering Design Process
Step 3 – Specification Ranking – At some level, determine what is important… – Use a weighted objectives table to determine what is important.
Step 4 – Brainstorm Design Concepts – Draw up all ideas, try to visualize how to solve the problem. – There are no bad ideas! One idea that doesn’t work out may
inspire another that does.
Step 5 – Prototyping – Step 4 & 5 are linked together… – This is the fun part – Play Around! – Sketch it, try it, tweak it... IMPROVE IT.

Engineering Design Process
Step 6 – Select an Approach – What worked best? – Define “best”? – How do you decide?
Step 7 – Detailed Design – CAD Everything! – Think “it” through.
Maintenance, Assembly… The devil is in the details.
– Probably one of the longest stages in the process…

Engineering Design Process
Step 8 – Manufacturing & Implementation
– Build the robot…
– Produce marketing packets
– Create a maintenance plan
Step 9 - Analyze Results
– Finish early… test at home!
– Check against your specs.
– Check against expectations.

Engineering Design Process
Step 10 – Refine the Design
– Determine if things can be improved.
– Don’t be afraid to go backwards.
– Redesign and test out new methods.
– Use all the time you get constructively.
– DON’T GET STUCK TRYING THE SAME THING OVER AND OVER!
– The definition of insanity is doing the same thing over and over and expecting different results!
