Blokzincir Destekli Mobil Robotların Sağlık Hizmetinde Uygulanması: Kullanım Örnekleri, Araştırma Zorlukları ve Gelecek Trendler

Öz

İnsan emeğinin riskli görüldüğü pandemi gibi acil durumlarda hizmet robotlarının sağlık hizmetlerinde kullanılması önem kazanmaktadır. Mobil robotlardan oluşan çoklu robot sistemleri, sağlık hizmetlerinde basit ama hayati görevleri yerine getirme potansiyeline sahiptir. Ancak bu sistemlerin bir sunucu bilgisayar ile merkezi kontrolü, tek arıza noktası ve robotların etkisiz çalışması risklerini taşır, bu nedenle blok zincir entegrasyonu ile merkezi olmayan kontrol daha iyi bir çözüm sunar. Bu çalışmada blokzincir destekli çoklu mobil robot sistemleri ile ilgili araştırma zorlukları; örnek kullanım durumları, blokzincir teknolojisi ve tıp merkezlerinde kullanılan mevcut bilgi işlem sistemlerine entegrasyonu açılarından ele alınmıştır. Ardından, izne bağlı erişimli bir blok zinciri platformu olan Hyperledger Fabric kullanarak çoklu robot sistemlerinde merkezi olmayan yönetim ve görev dağıtımı için bir yöntem önerilmekte ve ortak kullanım senaryoları verilmektedir. Sözkonusu sistemde, görev hedefine en yakın faal robotların seçimine bağlı olarak robotlara görevler atanmaktadır. Her robot, görev atama fonksiyonunu içeren akıllı sözleşmeyi çalıştırmakta; böylece görev atama işlemi için veri trafiği, merkezi bir sistemde olduğu gibi tek bir hatta yığılmak yerine ağ üzerine dağıtılmaktadır. Gelecekteki araştırma konuları ve gelecekteki çalışmalar için yönelimler de sonuç kısmında belirtilmiştir.

Application of Blockchain Powered Mobile Robots In Healthcare: Use Cases, Research Challenges and Future Trends

Öz

Using service robots in healthcare is gaining importance in case of emergent situations like pandemics where human labour is considered risky. Multi robot systems of mobile robots have the potential to perform simple but vital tasks in healthcare. However, centralized control with a server computer of these systems carry the risks of single point of failure and ineffective operation of robots, thus decentralized control with blockchain integration offers a better solution. We mention research challenges regarding blockchain powered multi robot systems of mobile robots from use case, blockchain technology and its integration into current computing systems used in medical centers aspects. Then we propose a method for decentralized management and task distribution in a multi robot system by using Hyperledger Fabric as a permissioned blockchain platform and give common use case scenarios. In this system, tasks are assigned to robots depending on the selection of nearest available robots to the task target. Each robot runs the smart contract containing the task assignment method, so that data traffic for the task assignment process is distributed among the network, instead of stacking up on a single line as in a centralized system. Future research issues and directions for future works are also stated as a conclusion.
