I got a lot of building problem using ubuntu1804 on Jetson Xavier Nx. Mainly because of different ros version. Is there any plan of providing building script for ubuntu1804?

After the delivery, the drone has to turn back and generate the new trajectory to come back. But it is not generating new path and following the same path which was generated

I wanted to ask why specifically TX2 is used and not any CUDA capable GPU?

The future_collision node is halting with following assertion failure.

eigen_assert((internal::UIntPtr(eigen_unaligned_array_assert_workaround_gcc47(array)) & (15)) == 0
&& "this assertion is explained here: "
"http://eigen.tuxfamily.org/dox-devel/group__TopicUnalignedArrayAssert.html"
" **** READ THIS WEB PAGE !!! ****");

Basically, all the steps under "Building" are done without any errors. Issues rise when I tried to run it on Companion Computer (Nvidia Jetson TX2).

After sourcing the relevant files, I run the command as told by the documentation here (https://github.com/harvard-edge/MAVBench/blob/master/docs/read_me/running.md)

roslaunch package_delivery scanning.launch

where it gives the error message as following:

Thanks in advance!

During simulation, there is no mobility in object or person which drone follows.
I tried the following, but the issue remains unresolved.

1. I did not find any other config file related to "follow_the_leader" in test_benches/configs folder. After going through the scripts code, I created new config file. I changed the "map_name" key to "follow_the_leader_simple" and added "time_to_trigger_object" key with value 5 in that new config file.
   Do I need to add any other key-value pair in config file?
2. I run "trigger.exe" file and gave 5 as input.

In 3d Mapping benchmark, the nbvplanner node has to generate the collision free paths. But in my case all the generated paths are colliding paths as shown below. So there is no progress in the benchmark mission.
I tried chaging the following parameters. But It did not resolved the issue.

1. sensor_max_range - increase
2. planning_resolution - decrease
3. mapping_resolution - decrease
4. system/bbx/x, system/bbx/y, system/bbx/z, system/bbx/overshoot, bbx/minX, bbx/minY, bbx/minZ, bbx/maxX, bbx/maxY, bbx/maxZ, - decrease
   

I 'm trying to build the companion computer .But when the terminal process catkin package: 'octomap_server', it shows that "No package 'openni-dev' found" and "No package 'openni2-dev' found" .How can I solve this?
Thanks in advance!

Hi Behzad,
I don't have a Jetson TX2. Searched for emulators for Jetson, sadly there isn't.

What can I use instead for this setup and benchmarks?

When I execute the instruction on the TX2, it shows me that the FindEigen.cmake Module in the cmake_modules package is deprecated. I follow the advice to change instances of find_package(Eigen) to find_package(Eigen3).But I failed. How can I solve this?
Thanks in advance.

In the attached images, at the beginning of execution, the images from camera sensor are being received and point cloud is generated.

But using this point cloud, the octomap has to be generated which is not happening. Because of this, the drone is colliding with the wall. We can see in the attached images.
While travelling on the generated path , the obstacle is determined using the octomap. As the octomap is not generated correctly, the drone is colliding with the obstacle.

We are trying to use MAVBench for our research, and using a Jetson TX1 for our work. We are studying the implication of running a given task on the onboard CPU vs. GPU (in our case, the Arm A57 or the Maxwell) of the TX1. So, we want to run each of the “nodes” in the applications in Fig. 7 of your paper (e.g. mission planning:scanning) on either the TX1 CPU and GPU, and profile their timing. Within the Github code in your repository, do you know if there is a way to select which device (CPU/GPU) runs a given node?
