I have tested figure 8 and trajectory following. They are working perfectly.

I would like to know how can I send the goal/ trajectory setpoints to the voxl-mapper to use rrt* to create the trajectory and to follow that.

I don't think I can just send it to /fmu/in/trajectory_setpoint, can I?

thanks in advance.

I am trying to archive getting Voxl-mapper to run by using the TOF-sensor. I studied the developer bootcamp and all the the given documentation but I didn't manage to figure out what Sensor configuration to use and which sensors to buy. I saw there ist a page called supported architectures which show possible configurations. Does that mean I have to chose a given configuration or ist it possible to just use the TOF-sensor for Voxl-mapper? What would be the configuration with the smalles amount of sensors to get Voxl-mapper running?
I am thankful for all kinds of help!

I found a table that states it will be supportet in the future: https://docs.modalai.com/M0178/?utm_source=chatgpt.com
Do you know when we can expect it ?

Quick question! I have a m500 (Voxl-flight) drone and I am trying to run the voxl-mapper on the portal. I am wondering if I will need to purchase a TOF sensor separately. The drone came with Hires 4k Image Sensor and Stereo Image Sensors. is a TOF sensor required for the mapper to work? Thank you in advance.

Also if I want to run the voxl2_mapper with the voxl-dfs-server and no time of flight? How can I check the pipes or what is the output pipe of the voxl-dfs-server?

@Zachary-Lowell-0 Does voxl-mapper need a TOF sensor to work properly?

1 Reply Last reply a day ago Reply

@plub yes you need a modalAI tof for voxl-mapper to work properly - you can technically get by by using another TOF sensor but then youd personally need to write the code to popuilte the MPA with pointcloud data the the voxl-mapper client is subscribing to.

The map is published in real-time by voxl-portal to a websocket at: ws://<VOXL_IP>:80/mesh.
If you would like to process the map real time without reading from disk, you could have another service connect to the socket and parse the binary data as defined here in voxl-portal:

There are two answers to your question:

You can pipe depth input from voxl-dfs-server (if you're running stereo cameras) to voxl-mapper, or any other service that you may create that produces depth estimates (i.e. if you had a depth from motion project).

We absolutely plan to support the tof camera on voxl2, we're working on this right now internally and hope to support it in the next month or two.

This looks like a version mismatch between the voxl-voxblox you built against and the version you have on your VOXL.

To ensure the versions match, you need to install the build dependencies from the last release in voxl-cross before deploying to voxl. This can be done by running:

./install_build_deps.sh apq8096 sdk-0.8

instead of

./install_build_deps.sh apq8096 stable ]]>https://forum.modalai.com/topic/1196/voxl-mapper-able-to-build-but-missing-symbol-on-the-boardhttps://forum.modalai.com/topic/1196/voxl-mapper-able-to-build-but-missing-symbol-on-the-boardFri, 12 Aug 2022 07:23:16 GMT
