2024- FEEDBACK Request from Isaac Sim Users

Omniverse Isaac Sim
42

Hi @alcosta

Isaac Sim requires as Minimum Spec an Intel Core i7 (7th Generation) processor.

Please, open a new topic (so, we leave this topic for feedbacks) if you wish to continue responding.

43

A 2060 GPU is way below specs as well. It requires AT LEAST a 3070

44

In such case it would run slowly, but not crash

Alternatively, if it is so crucial Iā€™d recommend creating a small test at the beginning saying ā€œSorry you canā€™t run this as you donā€™t have the minimum specsā€, as Iā€™ve seen in other nvidia products

Hope that is useful and I created a new topic

45

No not true. We have min specs for a reason. Below a certain level, it simply does not work, not runs slowly. It is a 3070. We publish min specs clearly with this in mind.

I would like the ability to run additional scripts on existing simulations.
Additional scripts would be used to generate robots and add sensors.

I am working on a tool to help ROS 2 users use Isaac Sim like Gazebo.
hijimasa/isaac-ros2-control-sample: This repository provides various utilities (operation with ros2_control, automatic sensor generation and sensor data publishing) for easy use of Isaac Sim. (github.com)
Gazebo has a command to generate robots, so I need similar functionality.
Currently I am using the Python REPL to accomplish this, but it requires a sleep command before and after to execute additional scripts.
Also, the Python REPL cannot handle multiple scripts simultaneously.
This takes time to generate multiple robots.

  1. Tutorials and documentation are slightly hard to follow. They look too nested and way too much information.
  2. Help when stuck at tutorials is hard to get resolved and make us move away.

I agree that the documentation is confusing.

I am currently trying to simulate a LiDAR called UST-30LX from HOKUYO, but I am facing a problem where the Azimuth angle in the configuration file cannot be set correctly.

On the other hand, I also encountered a discrepancy where the sample named Example_Rotary is set to -3 to 3 degrees in emitterStates, but it can measure 360 degrees.

There is an explanation of what each parameter in the configuration file is.
https://docs.omniverse.nvidia.com/isaacsim/latest/features/sensors_simulation/isaac_sim_sensors_rtx_based_lidar/lidar_config.html
However, I would like a good explanation of how they should be set.

50

We wish critical issues, like XR extensions being broken in Isaac Sim 4.0/4.1, are addressed more quickly with hot fixes.

51

Why was omni.isaac.repl, the only extension that could run additional Python scripts, deprecated?
Is the vscode extension a replacement?

52

You should carefully check the required NVIDIA driver version for installing isaacsim, as your NVIDIA driver version does not match, resulting in an error

53

Iā€™m thinking we need a bat file for a full OV/IS/ROS2 install.

Due to agentic workflows and docker builds it would be super handy for speedy workflows.

I know you guys might not have time Iā€™ll try to build it but itā€™s a worthy project. Iā€™m not a dev or programmer but this type of system would be so useful as I think user base for IS has a lengthy process before they can start working nevermind actually trying to devā€¦

54

I had a lot of trouble importing my URDF from ROS2. I had to do it manually, which took about a week (while learning IsaacSim). It has a mimic joint, which is a little bit unusual but just a little.

55

Being active on the forums and responding to help requests quickly is very important, too.

56

Could you create a topic to elaborate on the steps you took during the manual import process? Specifically, it would be great to understand:

  • How you recreated the robot model within Isaac Sim.
  • Any particular challenges you faced with the mimic joint and how you resolved them.
  • The tools or features in Isaac Sim that you found most helpful during this process.

Additionally, what led you to choose manual import over using automated tools? Was it due to specific limitations or issues with the URDF importer, or were there other factors at play?

57

I donā€™t remember enough now to specifically answer your questions. Iā€™d suggest to hire an intern whoā€™s never used IsaacSim before but is familiar with ROS. Then ask them to simulate a robot, recording their missteps along the way.

Thatā€™s absolutely a good idea.! The API and documentation of IsaacSim are too fragmented. It has never provided sufficiently concise sample codes to initialize a camera or a robotic arm, making the learning curve of IsaacSim extremely steep. Itā€™s a nightmare even for those familiar with robot simulators. For me, IsaacSim is like a delicious can of food, but I donā€™t have a can opener, T^T

Hi rthaker, we are an robot arm company, we want integrate our robot arm into Isaac Sim platfom, we want add our robot model into the library, while we met some troubles in developing with the Isaac Sim, would you please assist us a little bit? I appreciate for your kind, please reply to lancer.yao@ufactory.cc, thanks.

Hi @lancer.yao - Thank you for the message. Can you pls send a DM with more details and areas where you need help?
