Computation offloading for cloud robotics is receiving considerable attention in academic and industrial communities. However, current solutions face challenges: 1) traditional approaches do not consider the characteristics of networked (NCR) (e.g., heterogeneity robotic cooperation); 2) they fail to capture tasks a streaming workflow (RSW) strict latency requirements varying task semantics); 3) quality-of-service (QoS) issues robotics. In this paper, we address these by proposing QoS-aware...
