i-Walk

iWalk: Intelligent Robotic Walker for mobility and cognitive assistance of elderly and motor-impaired people

About the Project

The i-Walk project aims at developing and testing a new pioneering robotic system that will provide a range of mobility and cognitive support functions for people that face different degrees of mobility and cognitive problems.

In this project, the following methodologies will be developed and synergistically utilized: (a) processing of multi-sensory and physiological signals and identification of actions for the monitoring, analysis and prediction of human gait and other actions of the user, (b) behavioral and user-adaptive robot control and autonomous robot navigation for the dynamic approach of the user and the interactive co-occurrence combined also with voice guidance; (c) human-robot communication, including speech synthesis and recognition technologies and a virtual assistant (avatar) to enhance the naturalness of communication
