6. Build a Robot...ANY Robot
● Use the K’nex
● Pick a pair
● Decide who is the driver and navigator

7. Driver
● Concentrate on assembly
● Follow Navigator's lead
● Think about
implementation
Navigator

Think what to build
Describe design
Help selecting parts
Think about the bigger
picture

17. What did you think?
Well
●
●
●
●
●
●
●
●
●
●
Creativity introduced
learned new techniques
showed up knowing how to do things
Enjoyed watching others with robot
When confronted with all new, liked having
a pair to hash things out
Less fear of the unknown
Experimented more
Shared responsibility
Context switching makes you think
Learning from pair
Less Well
●
●
●
●
●
Too much guessing with new context
(sometimes)
Pair is not productive when both are newbies
Need some context to remain to keep
requirements clear
Documentation needed if context is not
preserved (stories, docs, requirements)
Pair may have separate, but applicable role

members
○ talks, short pairing sessions, discussions

● Start small - it doesn’t need to be a
Movement
