软件架构 - Software Architecture
我们基于ROS 2实现了大部分的机器人应用, 如架构图所示, 包括多设备链接、多模态感知、多模态人机交互、自主决策、空间定位、导航和目标追踪等功能. 目前使用的DDS中间件是Cyclone DDS, ROS 2的版本为Foxy.
Most of the robot applications are implemented based on ROS -As shown in the framework diagram, it includes functions such as multi-device connection, multi-modal perception, multi-modal human-computer interaction, autonomous decision-making, localization, navigation, and target tracking. Currently, the DDS middleware in use is Cyclone DDS, and the ROS 2 Package is implemented at Foxy.
由于NVIDIA对Jetson系列截至目前（202109）只提供了Ubuntu 18.04的支持, 故我们对Ubuntu 18.04进行了ROS 2的适配和修改. 具体的修改内容可以通过mini.repos进行拉取, 我们去除了部分没必要的仓, 并添加了一些需要使用的仓库（文件是Galcatic版本的, 我们会在后续适配到该版本）.
Due to NVIDIA only provides support for Ubuntu 18.04 for the Jetson series (202109) as yet, we have adapted and modified ROS 2 for Ubuntu 18.04. The specific modification content can be pulled through mini.repos. We have removed some unnecessary repositories, and added some repositories that need to be used (The file is of the Galactic version, and we will adapt to this version in the future).
