GRINS - Robòtica Intel·ligent i Sistemes

 

L’activitat del grup de recerca GRINS és el desenvolupament de sistemes robòtics intel•ligents, d’aplicació en camps poc estructurats en que, per la seva complexitat, no és possible una preprogramació de la tasca, com és el cas de la robòtica mèdica (quirúrgica, neurorehabilitació i assistencial) o en determinades aplicacions de la robòtica industrial o de serveis.
Les seves tres àrees temàtiques de recerca: robòtica, visió per computador i sistemes empotrats, conflueixen en els diferents projectes de recerca i transferència de tecnologia reforçant-se entre elles. En aquests àmbits, el disseny i la implementació requereixen d’una interacció persona-robot intuïtiva que precisa de sistemes de percepció, especialment visió, i la interpretació del context de treball. La implementació de sistemes intel•ligents comporta per a moltes aplicacions, la distribució d'aquesta capacitat tant a sensors com a mòduls de control descentralitzats, utilitzant tota la capacitat dels sistemes empotrats.

The group?s main field of research is the study, analysis and development of systems that involve advanced robotic systems that have perception capabilities and distributed control, which can thus achieve more intelligent and flexible behaviours. This subject is extremely broad in scope. The group focuses mainly on the development of multiagent systems (robots and persons) that have cooperation capabilities. It also works on the study, analysis and design of distributed control systems, where communication, real-time computing and advanced control algorithms are relevant issues. The research is oriented towards solving scientific and technological problems, both in the industrial sector and in non-industrial fields. The group is currently working on projects related to medical robots, underwater robots, mobile robot control and distributed control of automobiles.
