This competition aims to reduce the burden of employees by robot technology and realize a future convenience store that provides new services to customers. Participants compete on the following three tasks. The participant who will participate either one of three tasks are also welcome.

  1. Stock and Disposal Tasks
    Self-stocking of daily products (onigiri rice ball and bento lunch boxes, etc.) and disposing expired products.
  2. Customer Interaction Task
    Demonstration of future / sophisticated customer service in near future using robot technology.
  3. Restroom Cleaning Task
    Cleaning of the toilet bowl, and the floor in toilet stall.

Participants in this competition will develop a robot system that autonomously moves and performs these tasks, as well as the infrastructure they deem necessary to install inside the convenience store. In this challenge, the participants will use their developed robots and infrastructure to demonstrate and compete in these tasks  inside a simulated convenience store.
