unav-sim's Issues

build.sh building succesfully, throwing some errors after build

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:

Motor Control

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?

Issue with setup.sh

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 :).

Some Platforms were skipped due to invalid SDK setup: Android.

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.
 ---> System.IO.IOException: Permission denied
   --- End of inner exception stack trace ---
   at System.IO.FileStatus.ThrowOnCacheInitializationError(ReadOnlySpan`1 path)

It seems like it needs sudo permissions for accessing that folder

Is there a sample project?

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.
