Motion Matters: Analyzing Robotic Arms and Preparing for User Interviews
How can we analyze and describe different types of robotic arm motion to design a solution that meets a real user's needs?
Learning Intentions:
Analyze types of motion, describing them mathematically, and prepare to gather authentic user needs through thoughtful interviews.
Today's Concept:
You know the user's task involves cycles and angles. But is it a smooth, continuous wave like stirring a pot? Or is it a jerky, start-stop motion like stamping envelopes?
A robot needs to know the difference. A motor programmed to spin continuously will break if you force it to start and stop constantly. Today, you become motion detectives. You need to look closely at your user's task and break it down into its fundamental types of movement. This analysis will tell us what kind of mathematical functions we will need later to control the robot.

Peer Coach – Interview Question Drafting & Feedback
Your homework this weekend is to interview a real person about a task that is tiring, repetitive, or hard. Ask your planned questions. Bring notes and motion details back for Monday!
Take a photo, make a sketch, or write detailed notes about any motions the user describes so you don’t forget.
Next week, you’ll use what you learned in your interview to start designing a robotic arm solution. We’ll sketch, plan, and simulate motion using the trig skills we’ve practiced.
