The Journey Proposal became Spec (and changed) Proposal became Spec (and changed) First ones to get a HockeyBot Running First ones to get a HockeyBot Running –Unit Testing/Quick Small Iterations –Versioning –Everyone Else was a 48h before due –Simple Architecture (Subsumption) Many, Many Issues Many, Many Issues –Camera Lag –Camera Packet Loss –Chassis Iterations –Partner Problems Well Designed Processes Work Well Designed Processes Work

How JIM really works Subsumption based State Machine Subsumption based State Machine Minimal Abstraction Minimal Abstraction –Hardware Specifics are 1 class deeper (lean and mean) Different Sensors for different needs Different Sensors for different needs

Our Results Beat the schedule Beat the schedule –Working on PID Control which was not in proposal –Used tested 1 month old code in Final Got the A Got the A –Schedule –Documentation Didn’t win contest Didn’t win contest –Did do damage to competitors

Suggestions 1 Semester 1 Semester –ambitious time frame for a Senior Project –If you are not experienced in Java do tutorials now Default is that you use materials provided Default is that you use materials provided –JStamp/JStik/Amulet LCD/Sonar/Lego/ CMU Cam/Wireless Modem/Java Language –If you choose not to you must: Push Bruce for permission Push Bruce for permission Show compentency in the field Show compentency in the field Have your own budget available-now Have your own budget available-now Realize that the help available is minimal Realize that the help available is minimal Still accomplish the early tutorial assignments in Java Still accomplish the early tutorial assignments in Java
