BUDD-e
Blind-assistive aUtonomous Droid Device
PROJECT
Goals
The BUDD-e project involves a multidisciplinary research team (with expertises, e.g., in ICT, Robotics, and Architectural Design) to pursue a twofold ojective:
- design and realize a first prototype of the innovative autonomous robotic guide BUDD-e for blind and visually impaired persons, endowed with an innovative human-robot interface;
- design accessible and inclusive public places and indoor environments where BUDD-e can take the role of a guide for BVI persons and permit the fruition of the offered services.
The application scenarios include public spaces where the users will be able to reserve BUDD-e and use as an autonomous guide, e.g., hospitals, sport centers, shopping centers, parks, cultural centers.
Experimental validation tests are currently conducted in healthcare facilities (ASST Grande Ospedale Metropolitano Niguarda) and in sport centers (Centro Sportivo Giuriati, Milano).
Motivation
COVID-19 pandemics and related politics have strongly impacted on people’s life and, even more dramatically, that of vulnerable groups, e.g., people with visual impairment. The possibility to cultivate healthy relationships, take part to social events and activities, and to frequent public spaces has been restricted. Even everyday activities (e.g., use public services, shopping, practice sports) have been severely limited in the past 18 months.
According to the World Health Organization, BVI persons have particularly suffered from the COVID19 emergency and are still dramatically affected by the containment measures, being also particularly prone to the contagion risk. This is due to the fact that BVI need tactile contact with the environment and a guide for moving and orienteering.
People with visual impairment are 4% of the planet population (about 253 Millions). In Italy, they are just under 2 Millions among which 219,174 are absolutely blind (0.3% of the population), while 1,383,922 (2.3%) have a visual residue. Between 2010 and 2030 an increase of people with visual disabilities is expected by about 25% due to the population aging.
This large vulnerable group of persons has compelling and urgent needs to recover from the emergency social situation derived from the COVID-19 pandemics and to mitigate for the inequalities which have been exacerbated by it. This can be fostered by assistive technologies and inclusive environments.
OBJECTIVES
USER-CENTERED DESIGN
We have conducted a context analysis to highlight the desired features of the autonomous guide and the opportunities of improvement of spaces in terms of accessibiity. In particular, focus groups have been organized and questionnaires have been developed to analyze the needs of users and of the spaces. A final report (in Italian) is available here: “Questionari e Focus Group_Report“.
REALIZATION
BUDD-e is composed of:
– The autonomous vehicle YAPE, endowed with LIDAR sensors, cameras, and IMUs for autonomous driving and interaction with a highly populated and dynamic environment.
– A novel “smart tether system” for managing the human-robot interaction. It is endowed with a tether for connecting the robot and the users.
APPLICATION SCENARIOS
Analysis and design of accessible spaces is also a goal of BUDD-e. This goal will be achievedthrough the application of inclusive and user-centred architectural concepts that will allow to:
– Characterize the needs of orientation and signage;
– Define the optimal spatial and functional features;
– Innovate the fluxes and constraints with respect to the accessibility and usability of the spaces
The results will lead to an improved user experience in hospitals, sport centers, showpping centers, etc.
