· vscode中要先装置isaac插件Isaac Sim VS Code Editioncode .掀开之后,咱们测试一个demo,文献目次如下,加一个断点。图片
· 点击左侧的 run and debug按钮,点击debug即可。大意按F5也不错图片

在 Isaac Sim中,world 是一个单例对象,它处治仿真环境的举座情状。以下是一个小锻真金不怕火:1.掀开hello_world.py 文献。2.修改代码,通过再行创建一个新的 Stage(场景)。3.在剧本中添加一段逻辑,使用户不错点击按钮来加载 'Hello World'场景。4.同期,添加打印信息,以便在 Terminal中稽察有关教导或情状信息。通过以上头目,你将更直不雅地证实 Isaac Sim的交互经由以及world 对象的功能!https://docs.omniverse.nvidia.com/isaacsim/latest/core_api_tutorials/tutorial_core_hello_world.html4 回来Isaac Sim 的浩瀚不仅体当今其传神的仿真后果,还在于它为开辟者提供了纯竟然器具链和平方的推广可能。本期仅仅咱们探索之旅的驱动。在接下来的推文中,咱们将真切理会更多功能模块与实质诈骗案例,助你玩转 Isaac Sim。宽宥怜惜咱们,期待与你沿途在仿真天下中探索将来!附加贵府1.文档https://docs.omniverse.nvidia.com/https://developer.nvidia.com/isaac/simomniverse 开辟者文档https://docs.omniverse.nvidia.com/dev-guide/latest/index.htmlisaac sim 开辟者文档https://docs.omniverse.nvidia.com/isaacsim/latest/index.htmlisaac lab 开辟者文档https://isaac-sim.github.io/IsaacLab/isaac sim 写代码 API 参考文档https://docs.omniverse.nvidia.com/py/isaacsim/index.htmlisaac extension 文档https://docs.omniverse.nvidia.com/py/isaacsim/index.htmlros ros2 文档https://docs.omniverse.nvidia.com/isaacsim/latest/ros_ros2_tutorials.htmlhttps://player.bilibili.com/player.html?bvid=BV1a44y1N79U&autoplay=0AI 仓库:使用 Isaac Sim 和 Isaac ROS 结束视觉导航Autonomous machines are forecasted to dramatically increase the efficiency of warehouses, factories, and other industrial environments. NVIDIA Isaac ROS GEMs enable novel applications by empowering robots to intelligently perceive complex 3D environments. In this video, we showcase a camera-based navigation pipeline in which a robot uses NVIDIA’s GPU-accelerated visual SLAM algorithm (https://github.com/NVIDIA-ISAAC-ROS/i...) to find its location in the world. GPU-accelerated, real-time 3D scene reconstruction (https://github.com/NVIDIA-ISAAC-ROS/i...) is used to map its environment and plan collision-free trajectories. Finally, we demonstrate how Replicator, which is part of NVIDIA Isaac Sim (https://developer.nvidia.com/isaac-sim), can be used to procedurally generate industrial spaces in which to develop and validate robotics systems.
