DAY 1 · RULES & LEARNED PATTERNS
Robot Repair Shop
Two robots. Two different ways to decide.
Spot their mistakes and get the shop running again.
Watch · Stop · Repair
FROM THE DAY 1 LESSON
Why do they need different fixes?
Same shop. Different methods.
Day 1 compares rules written by people with patterns learned from examples.
You will repair one robot of each kind and see why the same fix does not work for both.
Robo-Learn
Learns from photos labeled Good or Bad.
Improve its examples.
Your job in the shop
