Edge Robotics: Edge-Computing-Accelerated Multi-Robot Simultaneous Localization and Mapping

Simultaneous Localization and Mapping (SLAM) is an strategy that aims to simultaneously construct a graphic map and keep track of the agent’s place in an not known setting, normally utilizing the edge robotics concept. A new paper, revealed on arXiv.org, proposes to leverage the emerging edge computing paradigm to complete multi-robot laser SLAM in lower latency.

Edge computing makes use of vicinal computing methods in bodily proximity to end devices to shorten details conversation distance, lower offloading transmission hold off, and permit the highly developed good quality of providers. The proposed structure exhibits that migrating SLAM workloads from robots to edge servers can successfully increase the robots’ processing functionality.

It is also revealed that merging a subset of local maps at the edge shrinks details dimensions and lessens conversation expenses. The simulation of the strategy demonstrates its effectiveness, and a sensible prototype on three robots verifies its feasibility and validity.

With the wide penetration of clever robots in multifarious fields, Simultaneous Localization and Mapping (SLAM) system in robotics has captivated increasing attention in the neighborhood. Still collaborating SLAM over various robots continue to stays complicated thanks to general performance contradiction between the intense graphics computation of SLAM and the confined computing functionality of robots. When classic solutions vacation resort to the potent cloud servers performing as an exterior computation company, we show by serious-world measurements that the sizeable conversation overhead in details offloading prevents its practicability to serious deployment. To tackle these challenges, this paper encourages the emerging edge computing paradigm into multi-robot SLAM and proposes RecSLAM, a multi-robot laser SLAM technique that focuses on accelerating map building system less than the robot-edge-cloud architecture. In distinction to regular multi-robot SLAM that generates graphic maps on robots and absolutely merges them on the cloud, RecSLAM develops a hierarchical map fusion system that directs robots’ uncooked details to edge servers for serious-time fusion and then sends to the cloud for international merging. To enhance the overall pipeline, an effective multi-robot SLAM collaborative processing framework is launched to adaptively enhance robot-to-edge offloading tailor-made to heterogeneous edge resource conditions, meanwhile ensuring the workload balancing amongst the edge servers. In depth evaluations show RecSLAM can realize up to 39% processing latency reduction over the condition-of-the-artwork. In addition to, a evidence-of-concept prototype is formulated and deployed in serious scenes to show its effectiveness.
