SaS Seminars

Software and Systems Research Seminar Series


The SaS Seminars are a permanent series of open seminars of the Division of Software and Systems (SaS) at the Department of Computer and Information Science (IDA), Linköping University. The objective of the seminars is to present outstanding research and ideas/problems relevant for SaS present and future activities. In particular, seminars cover the SaS research areas software engineering, programming environments, system software, embedded SW/HW systems, computer systems engineering, realtime systems, parallel and distributed computing, and theoretical computer science. -
Two kinds of seminars are planned:

  • talks by invited speakers not affiliated with SaS,

  • internal seminars presenting lab research to whole SaS (and other interested colleagues).

The speakers are expected to give a broad perspective of the presented research, adressing the audience with a general computer science background but possibly with no specific knowledge in the domain of the presented research. The normal length of a presentation is 60 minutes, including discussion.

The SaS seminars are coordinated by Christoph Kessler.

Self-adaptive cobotic systems with Context-Oriented Motion Grammars

Prof. Uwe Assmann, Technische Universität Dresden

Wednesday 11 january 2023, 15:15 in Ada Lovelace Abstract:
In industrial applications, humans and robots should safely collaborate with each other. This requirement initiates the new field of cobotics, in which all applications are human-robot collaborations that should be certified on safety and other critical conditions. To this end, formal methods such as grammars, automata, or petrinets have be used in the past, but can they also be beneficial for cobotics?
We present a new approach for self-adaptive cobotic systems based on an extension of attributed grammars called context-oriented motion grammars (COMG). This approach generalizes the well-known motion grammars, but additionally separates the concerns of sensorics and actuatorics. On the one hand, COMG use a context grammar parsing complex events of the world around the robot (for instance, human activities), and, on the other hand, a second reactive grammar for cobotic reactions. In this way, sensorics and actuatorics are separated like in the human nerval system, and with the two coupled attributed grammars, complex events and reactions can be formulated and, subsequently, automatically transformed to robotic control code, even for distributed platforms. We show a demo for a generic cobotic use case, the cleanup of messy scenes. Overall, the approach has the potential to provide substantial software reuse in complex cobotic applications in industry and beyond.
