Timeline

Five months. Two phases.
Mar → Jul 2017 · Planning & design → field operation & QA iteration
Mar
2017
Planning — Concept Definition
Core scenario concept locked in. Roles and scope defined between KEB Hana Bank Social Contribution Division and Robocare engineering team.
  • UX scenario concept concretized
  • Scenario content confirmed with stakeholders
  • Robotics functional requirements defined
Apr
2017
Design — Interaction & Display
Full 6-scene interaction arc designed. Display screen layout per scene. Robotics navigation paths mapped.
  • Display screen UI/UX designed (per-scene content + transitions)
  • Emotion expression and TTS speech designed
  • Robotics motion + navigation path designed
  • HAI character persona finalized
May
2017
Development — Build & Integration
Robocare engineering team implemented all interaction layers. Display UI, speech acts, robotics functions, and navigation built and integrated.
  • Screen UI/UX and TTS speech developed
  • Emotion expression + hand-sensor robotics implemented
  • Navigation and autonomous movement developed
Jun
2017
Field QA — Structured Pilot Review
A structured QA session documented critical field failures after the first pilot run. Issues triaged by severity. Improvement specifications written and handed off to engineering.
  • Speech-screen sync order corrected (quiz number / sound-effect ordering)
  • Voice recognition retry simplified: 3 attempts → 1 attempt
  • STT wait time reduced: 5 seconds → 3 seconds
  • Bingo game split into 4 resumable sub-scenarios
  • Robotics handoff transitions reviewed for smoothness
Jul
2017
Operation — 2-Month Live Deployment
HAI deployed in the KEB Hana Bank HQ Myeongdong B1F '1 Company 1 School' education hall. Real student cohorts — including North Korean defector youth from Yeomyung School — participated in the live program.
  • Live sessions run with actual student cohorts
  • Interaction data collected for technology asset base
  • First robot-led financial education PoC in Korean banking
