    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.

    创业加速器的价值在哪里?对企业融资能有多少帮助?

    现在,在科技领域创立一家公司只需要很小一笔资金就能够做到,我们可以看到有很多企业都是由新手创业者创立的。新手创业者不断出现的同时,全球范围内加速器的数量也快速增加,这些加速器在早期企业的发展阶段对创业团队给予支持。 很多加速器为同一批入驻的企业提供多种支持,比如导师培训,人脉网络,通常会以一小笔资本投入换取公司部分股权。很多加速器都会持有创业企业一部分股权,通常为5%-7%,所以从这一点来看,加入加速器的成本还是很高的。 决定是否加入一个加速器项目的关键因素应该是加速器在帮助公司后续融资方面能起到什么样的
