    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.

    简单介绍下:云计算

    传统模式下,企业建立一套IT系统不仅仅需要购买硬件等基础设施,还有买软件的许可证,需要专门的人员维护。当企业的规模扩大时还要继续升级各种软硬件设施以满足需要。对于企业来说,计算机等硬件和软件本身并非他们真正需要的,它们仅仅是完成工作、提供效率的工具而已。对个人来说,我们想正常使用电脑需要安装许多软件,而许多软件是收费的,对不经常使用该软件的用户来说购买是非常不划算的。可不可以有这样的服务,能够提供我们需要的所有软件供我们租用?这样我们只需要在用时付少量“租金”即可“租用”到这些软件服务,为我们节省许多购买软硬件的资金。

    如何基于云计算技术进行数据管理

    数据的快速增长导致用户对计算机计算能力的需求越来越高。云计算在提高普通计算机快速处理能力上起到了很大的作用。云计算能够对普通用户使用计算机的模式进行改变,从而给用户提供按需分配的存储能力、计算能力以及应用服务能力等,给用户带来更多的方便,也在很大程度上降低了用户对软件和硬件采购的费用。但是,云计算需要各种技术手段作为支持,其中包括虚拟化技术、分布式的储存方式、计算数据的管理以及数据同步运算等等。 1.云计算技术 云计算是一种基于网络的新的计算方式。云计算的核心思想可以追溯到上世纪60年代。利用云计算和计算机
