open-airlab / unav-sim Goto Github PK

When following these instructions:
cd ~/UNav-Sim/Unreal/Environments/Blocks
right-click on Blocks.uproject, select Unreal Engine Generate Project Files

I get the following error:

Discovering modules, targets and source code for project...
Unhandled exception: System.UnauthorizedAccessException: Access to the path '/home/freyja/Underwater_Simulator/UNav-Sim/Unreal/Environments/Blocks/Plugins/UNav-Sim/Content/VehicleAdv/SUV/AutomotiveMaterials/Textures' is denied.

It seems like it needs sudo permissions for accessing that folder

There are still some removal of folders for "Airsim" (as it is the baseline plugin for UNavSim), but they dont exist because of the new naming of the plugin. The error message:

Question

What's your question?

Hi!

I trying to evaluate whether the project I'm working on should switch from gazebo to UNav-Sim/Airsim.

We were interacting with simulated BueROV2s using Ardusub SITL from ROS2 through mavros before. We would like to be able to do something similar in Unreal to make sure that our software can run on real hardware, not just in the simulator.
Does anyone here know if that is supported in this project?
Is this guide applicable?: https://ardupilot.org/dev/docs/sitl-with-airsim.html

Also:
How does the ROS2 integration work?
Any ETA for the maps you used in the paper? (If they are being released at all?)

Include context on what you are trying to achieve

Multi domain, multi robot simulation to support the development of real world demonstrations.

I had some initial problems, but seem to have gotten the UNav-Sim started on ubuntu 22.04 at least!

Bug report

• AirSim Version/#commit:
• UE/Unity version: Unreal Engine 5
• autopilot version: N/A
• OS Version: Windows 10

What's the issue you encountered?

Followed the attached steps for installation of unavsim but build.sh continually throws errors relating to rpclib 2.3.0. When trying to install this rpclib version, am unable to find this specific rpclib version. Continuing to get errors even though I have the latest rpclib version.

Settings

How can the issue be reproduced?

1. Followed the installation instructions provided by the unavsim team, up until the unavsim setup part.

Include full error message in text form

echo 'ERROR: new version of AirSim requires newer rpclib.'
ERROR: new version of AirSim requires newer rpclib.

What's better than filing an issue? Filing a pull request :).

Question

What's your question?

When controlling the motion of the ROV using API(moveByMotorPWMsAsync) to manipulate the PWM of the motors, how should I reverse the motors to control the descent of the ROV?

Smaller Details:

I don’t know how to set up an underwater environment with this simulator. After I built a project, i can’t control the rov, which is suspended in mid air.
