    FogROS2 使用 ROS 2 的云和雾机器人的自适应和可扩展平台

    FogROS 2: An Adaptive and Extensible Platform for Cloud and Fog Robotics Using ROS 2 Abstract— Mobility, power, and price points often dictate that robots do not have sufficient computing power on board to run modern robot algorithms at desired rates. Cloud computing providers such as AWS, GCP, and Azure offer immense computing power on demand, but tapping into that power from a robot is non-trivial. In this paper, we present FogROS2, an easy-to-use, open-source platform to facilitate cloud and fog robotics that is compatible with the emerging Robot Operating System 2 (ROS 2) standard. FogROS 2 provisions a cloud computer, deploys and launches ROS 2 nodes to the cloud computer, sets up secure networking between the robot and cloud, and starts the application running. FogROS 2 is completely redesigned and distinct from its predecessor to support ROS 2 applications, transparent video compression and communication, improved performance and security, support for multiple cloud-computing providers, and remote monitoring and visualization. We demonstrate in example applications that the performance gained by using cloud computers can overcome the network latency to significantly speed up robot performance. In examples, FogROS 2 reduces SLAM latency by 50%, reduces grasp planning time from 14s to 1.2s, and speeds up motion planning 28x. When compared to alternatives, FogROS 2 reduces network utilization by up to 3.8x. FogROS2, source, examples, and documentation is available at github.com/BerkeleyAutomation/FogROS2.

    微软与谷歌的“云计算争霸赛”:人工智能才是关键看点

    【新智元导读】巨大的商业价值让云计算市场“狼烟遍起“,随着更多巨头加入了这场“战争”,云服务商们也展开了新一轮的“厮杀”较量。本文讨论了谷歌和微软两家科技巨头在云服务领域的竞争,最为重要的是,人工智能已经成为这场角逐的决胜力量。 事实证明,即便你还对云服务存有顾虑,但把你的公司业务迁到云端的理由似乎要更充分一些。 包括亚马逊AWS与微软Azure在内的一众云服务平台,能够为传统的数据存储方式找到挖掘更多的存储优势,譬如等级更高的安全性,灵活性与更好的可访问性,同时还能降低运营成本。 更重要的是,这些云存储平

    第四代算力革命(三):面向未来十年的新一代计算架构

    编者按: 新华社北京2022年2月17日电,记者了解到,国家发展改革委、中央网信办、工业和信息化部、国家能源局近日联合印发文件,同意在京津冀、长三角、粤港澳大湾区、成渝、内蒙古、贵州、甘肃、宁夏启动建设国家算力枢纽节点,并规划了张家口集群等10个国家数据中心集群。至此,全国一体化大数据中心体系完成总体布局设计,“东数西算”工程正式全面启动。 当前,算力已成为全球战略竞争新焦点,是国民经济发展的重要引擎,全球各国的算力水平与经济发展水平呈现显著的正相关。在2020年全球算力中,美国占36%,中国占31%,欧洲
