Interface (e. g. Alarm / Emergency buttonscognitive behaviour…) - Fault diagnostics * Fault detection and recovery * Graceful degradation (Several modes of operations - e. g. transport mode ) *Data logging (black box) * Preventive fault detection Other indirect potential research issues: Communication standards 1/3
INTEGRATION (OF 2. 1 & 2. 2) INTERFACING Global Management and Control of the whole system (smart combined unit + mobile robot platform) - global level - Hardware integration (2. 1) + (2. 2) - Software integration: * (a priori) Planning mission preparation (route planning) - of the mobile platform * (real time) Executive mission - Supervision -Trajectory control of platform and associated tools - Global Energy management - High level safety management (dynamic stability – fix and mobile obstacles) * (a posteriori) mission assess - Traceability Human operator place in the robotic loop ? Added Value for operator / supervisor / trouble shooter Man–Machine Interface - Usability Versatile remote HMI Control board Tuning parameter measurement & tune - User interface design Feedback of user interface PROTOTYPING Definition of criteria and metrics to evaluate solution - Environmental impacts (air pollution, soil respect, quality product) - Safety (operator, environment) - Autonomy (Energy, Mobility level) Demonstrator realization REGULATION Standardization - Mechanics - Communication Data standards * Definition and harmonization of communication protocols * Definition and harmonization of data format - Electronics - Platform System level - Peripheral Modules level Test - Validation of demonstrators - Laboratory conditions - Field conditions End-User involvement / user-centric development Legal aspects ex: Responsibilities issues in case of accident Final Certification - Homologation Value Chain legend Red: Lock – Not available soon on the market Orange: Not available yet, but possible to design and market quickly (1 -2 years) Green: Technology or knowledge currently available Black: Not coloured yet (generic title or information to color soon). Proof Of Concept Involvment of manufacturers, distributors and end users Possible extension to the management/control of several associated robots ? Other indirect potential research issues: Environnemental impact: Life Cycle Analysis 2/3
MANUFACTURING Product - Modular / scalable product systems (with other peripheral tools) / retrofit - Products recycling Means of production (Small batch production) - Choice of optimal components (electronic, mechanic, electric devices…) - Organization of production * Subcontractors contributions * Adaptation of particular production line systems - Machine recycling Business plan design optimization DISTRIBUTION Advertising - Website - Media events - Direct contact * Phone *Email * Meeting USES / DISPOSALS AFTER USE Customer appropriation - Economic adoption - “Easy to use" approval - Performance approval Facilities and services Red: Lock – Not available soon on the market Orange: Not available yet, but possible to design and market quickly (1 -2 years) - Technical brochures - Leaflet/paper publicity Value Chain legend Experience feedback - Value for money/ Return On Investment - Usability - Demonstration events Green: Technology or knowledge currently available Black: Not coloured yet (generic title or information to color soon). - Tools support * Associated services * Training Marketing - User identification Customizing - System composition New services (ex.
