Is there a way to control the tello drone with the computer keyboard ?

Thanks !

Hi got this error after I change from python2 to python3

line 77, in __init__
    super(TelloNode, self).__init__(
TypeError: __init__() got an unexpected keyword argument 'local_cmd_client_port' 

It seems like the init function of the superclass doesn't expect the local_cmd_client_port argument. The argument is coming from this snippet

super(TelloNode, self).__init__(
            local_cmd_client_port=self.local_cmd_client_port,
            local_vid_server_port=self.local_vid_server_port,
            tello_ip=self.tello_ip,
            tello_cmd_server_port=self.tello_cmd_server_port,
            log=log)

Hello,

I'm using Ubuntu 18.04 / Python 2.7.17 / Installed Pyav through (pip install av==0.5.2) / ROS Melodic.

When I try to launch tello_node.launch I'm still getting the error : no module named av.

Does someone have a workaround for this issue ?

Thanks !

EDIT : It seems like the pyAv is installed on python 3.6 folder. I have no idea how to install it on python 2.7 folder.

Any help is appreciated.

Hi guys, I new on ROS and Tello, I followed up the instructions but when I try to run "roslaunch tello_driver/launch/tello_node.launch" I get the following:

hi,

I want to control two or more drones at the same time without docker,is it possible?I create two socket with different wifi interface in the tello_driver_node.py, but it seems to conflict with its IP.

Thank you for your efforts to distribute ros driver for tello.

I got error message when I tried to run
rosdep install tell_driver

Error messages as follows :

ERROR: Rosdep cannot find all required resources to answer your query

hi.
thanks for package!
i tried to use it with ros noetic and ORB_SLAM3 - https://youtu.be/_RiNv0Zz7gI
but it seems it works poor.
i think the problem is in frame translation as it overloads.

i found some interesting issue in this case. have a look - damiafuentes/DJITelloPy#166 (comment)

may be that is the way to improve ?

p.s. i also checked orb_slam2, ros2 and tello dji - https://youtu.be/MaZRohrtnrQ
and it seems to me it has much better perfomance. but ORB_SLAM2 has no mono_inertial implementation (

hi!
i`m planning to use wth ORB_SLAM3 and already use with mono.
Do you know imu publish frequency to set it with mono_inertial ?

Hello people of Tello,
like the title says, I have a problem with the smoothness of the video stream.
Anyone an idea how to fix that?
best, samuel

Hi, I used two Tellos(not EDU) with your script with the help of two USB wi-fi dongles. However, when I disconnected and tried again with the same configuration, right now only one of the adapters can connect. (I changed the config files accordingly BTW). Is there something that I don't understand?

Also is there any method to stack all the wifi interfaces and Tellos to be connected to the same configuration file? What can I do to achieve that do you have any suggestions?

Your repo helped me a lot and I would be grateful if you can help me further.

I'm trying to view the drone frames using rviz, but I can't seem to find them. If i run rosrun tf view_frames I get the message "No TF data received". Is there a way to display the drone frames ?

I got these message below, as following your instruction.
(Most of errors happened because of PyAV package, and I solved that through installation from source.)

Do you know how to fix error as below?
It seems that the path should be fixed. [tello_driver/tello_driver]
I'm not familiar with ROS yet.
Please help me.

Hey there!

When trying to install the package, at the rosdep install h264_image_transport, I keep receiving the error:

ERROR: Rosdep cannot find all required resources to answer your query
Missing resource h264_image_transport
ROS path [0]=/opt/ros/kinetic/share/ros

EDIT: However, I am able to install the required packages by running

rosdep update
rosdep install --from-paths src -i

All these commands are ran from ~/catkin_ws.
How is this possible?

Hello,

I've been trying to get a compressed image message sent from the drone, and I cannot seem to have the topic /tello/image_raw/compressed publish anything. /tello/image_raw/h264 does publish the stream however; so how can I get the compressed image to publish the compressed image messages? Using ROS Melodic with everything else being up to date.

Hi! I'm trying to run the tello drone from Ubuntu 20.04 and ROS Noetic on a Virtual Machine

I have been able to establish a connection to the drone and send commands. I've even written a script that controls the drone with the keyboard. The only issue is that I'm not getting any video. It keeps throwing: video recv: timeout followed by a fgrab:pyav stream failed

I'm attaching the error messages I receive. I would appreciate any insight into any mistakes I could've done, since I haven't been working with ROS for a long time

Hi,

I'm getting an unusable image from the /tello/image_raw topic, it is 90% filled with green pixels. My laptop and the Tello drone are 50 cm away, and the WiFi link quality is perfect (70/70) with a Bit Rate of 54 Mb/s (this is the top value I get).

I guess the problem comes from the /tello/image_raw topic bandwith, that is around 62 MB/s (30 FPS). Is there any way of decreasing it?

I'm attaching a screenshot with the driver parameters and the image quality I get. Changing stream_h264_video to true or playing with the image quality parameter doesn't solve the problem.

Thanks in advance.

hello

hello , first congratulate you for your work done in the library of ros for drone tello, I'm doing a project with the drone tello, but when capturing the image comes out distorted (green pixel noise) and with delay, maybe you could help me How could I improve this inconvenience since I want to perform image processing in ros with the video obtained from the drone. For your help I give you my thanks

Hi, (just edited to update the error, the previous was trivial)

Thanks for this great work! I've installed the package following your instructions but I'm getting this argument error when launching the driver_node. How could it be solved?

Thanx in advance!

Seems like scipts are not converted to py3 yet which is default for noetic. Will there be support for this? Am i doing something wrong?

It looks like you have not downloaded + compiled h264_image_transport package. Check out the instructions here.

Thank you for your answer. I have followed all the instructions. I had some problem to install rosdep install h264_image_transport but in the end I manage by copying the file in the directory he asked me.

However, I still get the same problem, look at this screenshot:

In the picture you can see the installation was succesfull. But still get the same problem. I also have checked the files H264Packet.msg and it is in this adress:
