Title: Effective and User-friendly Specification of Multi-Robot Missions
When: Wednesday 24, April 15:00-16:00
Where: Aula seminari, blocco 0 

Abstract: Mobile robots are increasingly used in everyday life to autonomously realize missions such as exploring rooms, delivering goods, or following certain paths for surveillance. The current robotic market is asking for a radical shift in the development of robotic applications where mission specification is performed by robotic users that are not highly qualified and specialized in robotics or ICT. To this aim, we proposed a Domain Specific Language (DSL) that enables non-technical users to specify missions for a team of autonomous robots in a user- friendly and effective way. The talk will present how we developed such DSL, it semantics, and how we evaluated it.

Title: On Interfaces to Support Agile Architecting in Automotive

Abstract: In large-scale agile automotive companies, practitioners struggle with creating and evolving an architecture when developing complex and safety-critical systems. A key issue is the trade-off between upfront planning and flexibility to embrace change. In particular, the coordination of interfaces is an important challenge, as interfaces determine and regulate the exchange of information between components, subsystems, and systems, which are often developed by multiple teams. In a fast-changing environment, interfaces between teams can provide the sufficient stability to align software or systems, while maintaining a sufficient degree of autonomy. In this talk, we present an exploratory case study with an automotive OEM to identify characteristics of different interfaces, from non-critical interfaces that can be changed frequently and quickly, to those that are critical and require more stability and a rigorous change process. We identify what dimensions impact how interfaces are changed, what categories of interfaces exist along these dimensions, and how categories of interfaces change over time. We conclude with suggestions for practices to manage the different categories of interfaces in large-scale agile development.
