hi,
" To setup the model, first install and run Gazebo once... "

can you share procedure to install gazebo on the jetson?
I keep getting: "E: Unable to locate package gazebo11"

Hi,

I have installed the gazebo by following this link
http://gazebosim.org/tutorials?tut=install_ubuntu
I can run gazebo. and I have closed the gazebo properly and restarted the nano just to be safe.
But when I run this line, there is an error.
./install_jetbot_model.sh

checking for: /home/jetbot/.gazebo
checking for: /home/jetbot/.gazebo/models
error: please install and run Gazebo once before running this script

Do I need to modify the install_jetbot_model.sh?
But in the file system
~/workspace/catkin_ws/src/jetbot_ros/gazebo/jetbot
Inside, there are
meshes (folder) model.config model.sdf
there is no .gazebo

Btw, I am using this jetbot, it has its own SD card image. And I can run the motors and OLED. It won't affect the ros, right?
https://www.waveshare.net/wiki/JetBot_AI_Kit

Thanks.

So is this not compatible with the Jetson Nano B01 version 4.3 jetpack at all?

Can you help me rectify this i2c error. When i run the motors using jupyter notebook, it is fine. But with ros it is not coming properly. I am not knowing how to proceed. Kindly help

output when running roscore seems ok (see below), however when running eiither

• rosrun jetbot_ros jetbot_motors.py
  OR
• rosrun jetbot_ros jetbot_oled.py
  I am getting this print and nothing more..
  Unable to register with master node [http://localhost:11311]: master may not be running yet. Will keep trying.

Any advice would be greatly appreciated.

(
btw, motors works fine when I run a simple python script like -
from adafruit_motorkit import MotorKit
kit = MotorKit()
kit.motor1.throttle = SOME_VALUE
)

this is the output when running roscore -

I was trying to use Rviz and found Rviz does not support the sdf files file format. The Robot_description parameter can only handle the URDF formatted files. In addition, you will probably want to use the TF and robot_state_publisher...etc. Can the sdf be converted to a URDF?

After following this install procedure, how do i use jetbot simulation model to control??
I'd like to control this model by rostopic pub or something ROS interface. If you have any solutions, it's helpful for me.

As I understand the “jetbot_motors.py” code, and the note referring to “text commands only”, it is not a Node that Subscribes to the standard ROS “geometry_msgs/Twist.h” message that would be generated by, for example, a Joy Node to enable teleoperation by a keyboard_teleop or joystick_teleop Publisher? If so is there a plan to release a motor driver version that has this function? Thanks

I am using the 3/18/2019 Jetbot SD image.

I am getting two errors when I follow the instructions explicitly. I get that QT 4.X is a requirement and not loaded. I get the libopencv-calib3d-dev has an unresolved issue and libopencv-dev has a conflict.

The first issue when looking at the CMakePreBuild.sh is that the apt-get install is failing completely but then the script continues to run. It runs but finally stops at the missing QT.

So I run apt-get with each of the packages one by one. It is able to install everything but libopencv.

If I rerun CMakePreBuild again I get past the QT error but know I get an error with OpenCV. It says tha OpenCV is trying to overwrite /usr/bin/opencv_version which is also in a package libopencv 3.3.1.2-g31ccdfe11. Also a system pop up on the desktop says "a Ubuntu package has a file conflict with a package that is not a genuine Ubuntu package"

I have re-flashed the drive 3 times now. And the above is a 100% repeatable scenerio.

Has this actually been tested lately with the 3/18/2019 Jetbot SD image?

I want to connect jetson nano and android application via bluetooth. The signal(result of deeprunning) comes from the jetson nano to the smartphone, and I want to run the application according to the signal. Is there any way?

Currently, the ROS nodes (?) utilizes Python 2 for the hardware scripts, which was announced to be sunset a while ago: https://www.python.org/doc/sunset-python-2/

If the nodes (?), were to utilize Python 3, I could add in the functionality for the OLED display included in the SparkFun Kit: #37 (comment)

Is there anyway to configure the ros_deep_learning node to run with ros node usb_cam which outputs in rgb9 format instead of bgr format?

when i do rosrun jetbot_ros jetbot_motors.py
it is error

File "/home/lb/workspace/catkin_ws/src/jetbot_ros/scripts/jetbot_motors.py", line 5, in
from Adafruit_MotorHAT import Adafruit_MotorHAT
ImportError: No module named Adafruit_MotorHAT

but i had run :
pip install Adafruit-MotorHAT
pip3 install Adafruit-MotorHAT

where problem?

The camera image being published to ROS by jetbot_camera.cpp is upside-down. When reading the camera image directly with gstreamer with flip_method=0 the image the right way up, so the camera orientation on my robot is correct. Is it possible to have the image orientation published to ROS the same as gstreamer or add parameter similar to flip_method to the image publisher?

Currently have to either rotate the published image in ROS or rotate the camera when running ROS vs. non-ROS code.

Starting with the new L4T r3.22 image, I successfully completed the installation described in the Wiki by several additions, perhaps because several packages were in the original 58GiB image.

I successfully compiled all the packages,start the jetbot_camera node.But I get the image is all zero.

At the same time I can successfully run a separate jetson-interface.

thanks!

I am following the jetbot_ros tutorials step by step, while building jetson-inference, I am getting this error though,

Jetson Nano (Developer Kit Vesion) - Jetpack 4.4.1 [L4T 32.4.4]

I've followed the configuration, installation, and build steps as they were listed, but I get IOError: [Errno 121] Remote I/O error for the following commands.

$ rosrun jetbot_ros jetbot_oled.py
$ rosrun jetbot_ros jetbot_motors.py

I've double checked my connections and tried running my own script to test the qwiic oled. I'm able to connect and use the qwiic oled using the sparkfun-qwiic-micro-oled Python3 library.
import qwiic_micro_oled
my_oled = qwiic_micro_oled.QwiicMicroOled()
my_oled.begin()
my_oled.clear(my_oled.PAGE)
my_oled.print("Hello")
my_oled.display()

However, it doesn't seem to work with the Adafruit_SSD1306 library.

The fact that I'm able to connect and use the qwiic oled leads me to believe that this is not a connection issue... However, I am a beginner to these things so I may be wrong. Please let me know if I should provide more information

The error is as follows for $ rosrun jetbot_ros jetbot_oled.py:

Traceback (most recent call last):

self._device.write(data)
IOError: [Errno 121] Remote I/O error

This is the output when I run $ i2cdetect -y -r 1. Seems like the Nano is able to detect the motor driver and micro oled.

Hi, I am trying to setup the docker container to use ros2 Foxy in my Sparkfun jetbot. I saw the latest commit, where the compatibility with the Sparkfun robot was finally added, thanks a lot for that. I pulled from git and executed the run.sh to get the container up and running.
The problem is, once inside the container, none of the corresponding Sparkfun files are found, looking like the container is not in its latest version.
I tried running pull.sh but it did not introduce the desired updates. I then decided to build the container (build.sh) to see if that way I could have the latest version. However, doing so, I got stuck because of pip3 protobuf installation issues, which require Python >= 3.7. I am attaching the related lines of code in the DockerFile.

"RUN git clone https://github.com/dusty-nv/py3gazebo /opt/py3gazebo &&
pip3 install protobuf>=2.6 --verbose &&
pip3 install trollius --verbose &&
pip3 install pynput --verbose "

Am I in the right track to get the latest container? If so, how could I successfully build the container?
Thanks a lot for your help in advance!

Could you provide a link or the steps that shows how to "It is assumed that the Nano has been setup with JetPack 4.2 and that CUDA, cuDNN, and TensorRT have been installed."

Hello,

I try to use a webcam in ROS of Jetbot and encounter some error like a below picture.

I try to modify code at jetbot_camera.cpp. But, it is little difficult.

Can you help me how to use a webcam in ROS of Jetbot?

Thank you,
From Dohyeong

I am getting the following error.

I am sure I need something else before I run the shell command. Please help.

I had trouble installing the ROS Melodic from the command line:
sudo apt-get install ros-melodic-ros-base

Instead, I followed these instructions:
http://wiki.ros.org/Installation/Ubuntu

Note: You will need to run the command in section 1.3 to set up your keys before clicking the link in section 1.4.

I hope this helps others.

When i am writing this code i got an error:

I don't have jetbot but i need PCA9685 driver.
Can you help me?

CMake Error at jetbot+ros/CMakeLists.txt:19(find package):
By not providing ''Findjetson-utils.cmake'' in CMAKE_MOFULE_PATH this project has asked CMake to find a package configuration file provided by ''jetson-uitls'', but CMake did not find one

I am getting error while building the package jetbot_ros on my nvidia jetbot.
Attached the error logs
