Center Overview

In the CREST project, "Development and Social Implementation of PRINTEPS, a Framework for Building Practical Intelligent Applications," we are developing PRINTEPS, a platform for building diverse general intelligence that can co-evolve with humans by integrating five types of elemental intelligence: knowledge reasoning, voice dialogue, image sensing, motion, and machine learning (including deep learning).

In terms of practical application, we will implement and evaluate a robot cafe and a teaching assistant robot as an application of multi-tasking, multi-robot systems.

FY2019 Business Plan

■Regarding activities continuing from the previous fiscal year: background, rationale, and goals for continuation

Currently, there are six types of intelligent elemental technologies realized in PRINTEPS (knowledge reasoning, voice dialogue, continuous dialogue, image sensing of people and objects, intelligent limb movements, and machine learning (which is relevant to all)). However, as they remain at a level where each elemental intelligence is simply linked, we will enable bidirectional and multiple interactions between them to realize more attractive services.

■New activity goals and content for FY2019, and background for implementation

We plan to continue our joint research with Toyota Motor Corporation related to the HSR (Human Support Robot) this fiscal year as well.

FY2019 Business Report

■Implementation details for the fiscal year's business plan, research results, and degree of achievement

As a practical application of PRINTEPS, (1) at Suginami Ward Hamadayama Elementary School, we had the AI robot SOTA, which uses ontologies, participate in student group discussions. We confirmed that SOTA could answer questions from students, contribute to the development of the discussion, and vitalize the group discussions. Also, (2) we prototyped an udon chef AI robot and confirmed that it could recommend and prepare better ingredient combinations for customers while evaluating their requests based on nutritional knowledge, allowing us to envision a future society.
