ROBOTIS-Will commented 3 years ago

Hmm... Looks like you have followed a different installation than the eManual. If you don't need a GUI environment on Raspberry Pi, I'd recommend to Install with Ubuntu 18.04.3 preinstalled server ARM64 for Raspberry PI3 Please select the ROS version at the top of the page before following the instructions. https://emanual.robotis.com/docs/en/platform/turtlebot3/sbc_setup/

Paulino1956 commented 3 years ago

Hello!

Thanks for the recommendation, it worked ! However, after successfully running the “bringup” procedure and operate via RC-100, I got into new issues : lost wireless connection with Pi (no wlan0 and IP address).

After several unsuccessful tentatives, I have also tried using another RBPi OS, and was able to get the wireless connection working via Pi (including wlan0 and IP address).

Thanks for your help!

Hello - I still cannot connect Pi3 to Wi-Fi. I have configured the network, as per the e-manual.

Thanks in advance for your support.

@Paulino1956 Hi, operating TurtleBot3 with RC-100 remote controller doesn't reuquire ROS running as it directly receives command from the controller and interprets in OpenCR. Let me create a recovery image of Melodic for RPi3B+ and see if it works for you. This may take a few days. Thank you.

@Paulino1956 Hi, here's the Melodic test image for Raspberry Pi 3B+ that I built with my TurtleBot3 burger. https://www.robotis.com/service/download.php?no=2011

The user name is ubuntu and the password is turtlebot

Before using it, you need to open and modify the network settings.

$ sudo nano /etc/netplan/50-cloud-init.yaml

Replace the WIFI_SSID and WIFI_PASSWORD for your wifi settings.

Then open the ~/.bashrc file

$ nano ~/.bashrc

Modify where ROS_MASTER_URI, ROS_HOSTNAME, TURTLEBOT3_MODEL are defined.

# Replace IP_ADDRESS_OF_REMOTE_PC with the IP address of remote pc
# Both Remote PC and Raspberry Pi should be connected in the same local network
# e.g) export ROS_MASTER_URI=http://192.168.0.10:11311
export ROS_MASTER_URI=http://localhost:11311
# Replace IP_ADDRESS_OF_RASPBERRY_PI with the IP address of Raspberry Pi
# e.g) export ROS_HOSTNAME=192.168.0.11
export ROS_HOSTNAME=localhost

export TURTLEBOT3_MODEL=burger

Paulino1956 commented 3 years ago

Hello !

I executed the instructions as per your e-mail, and was able to make the Pi to access the Wi-Fi, and use ifconfig to get an IP address. As per the instructions, I made the modifications (on the nano ~/.bashrc ) using the new IP address.

After that, I was able to run ssh from the remote PC and connected to the Pi. I executed the procedure to the SBC set up and install the complete configuration including : ROS Melodic Meronia, the ROS Packages and Network Configuration. I started the installation of the OpenCR set up and had to stop, but properly shut down the PI. When I returned to ssh via the remote terminal it was not able to connect to the Pi again.

I run the PI on a terminal and use ifconfig to get the IP address, and got this message below:

The Pi is not connecting to the network, which was the same issue I experienced before. It seems like something - removes the Pi from the network - when we install ROS.

Again, I really do appreciate your continuous support.

Thanks,

Paulino

Paulino1956 commented 3 years ago

Achieved good progress! Almost there, but I experiencing few more issues:

Problem 1- Got everything working via ssh and follow instruction and launched Bringup, then teleoperation. I got the expected screen results, follow the instructions toon, but was not able to make the turtlebot wheels to move/rotate via the screen commands (I.e. moving around : a,w,s,x and d). At the same time, the terminal was responding and registering linear and angular velocity like the movement was happening.

Problem 2-

Run rqt - it did not work, and got the following results :

I was able to run SLAM Node successfully, and got RVIZ operating on the screen. Then, I run the Teleoperation Node procedure, but again was not able to move the Turtlebot from the Remote PC.

Problem 3- I was note able to run the Navigation Node. When I run (on the Remote PC) the instruction $ roslaunch turtlebot3_navigation.launch map_file:=$HOME/map.yaml, the RVIZ did not run properly on the screen and it shutdown after trying to locate the map.

Thanks in advance for your support!

Hi, What did you get from running the rqt install command below? Were there any errors or warnings?

$ sudo apt-get install ros-melodic-rqt*

Could you try reading the ROS topics from the Raspberry Pi on TurtleBot3 with the command below?

$ rostopic list

I'm not sure why rqt is not working with your PC. I'd recommend to reinstall the desktop full version of ROS and TurtleBot3 packages on your PC.

I need to see if Raspberry Pi and Remote PC is properly connected in the same network and sharing the ROS topics to each other. In order to confirm this, $ rostopic list will list up the topics in the current network. Also, when running the teleop keyboard from the remote PC, check if cmd_vel topic is correctly updated from the Raspberry Pi with entering below command.

$ rostopic echo /cmd_vel

On the Pi (via SSH from the PC)-

This is what I get when I run : $ rostopic list @.:~$ rostopic list ERROR: Unable to communicate with master! @.:~$

also on the Pi (via ssh from the PC) - @.***:~$ rostopic echo /cmd_vel ERROR: Unable to communicate with master!

I will reinstall ROS on the PC and get back to you shortly.

Thanks,

Hi, What did you get from running the rqt install command below? Were there any errors or warnings?

$ sudo apt-get install ros-melodic-rqt*

Could you try reading the ROS topics from the Raspberry Pi on TurtleBot3 with the command below?

$ rostopic list

I'm not sure why rqt is not working with your PC. I'd recommend to reinstall the desktop full version of ROS and TurtleBot3 packages on your PC.

Some more progress today !!

I was able to execute on PC - @.***:~$ roslaunch turtlebot3_teleop turtlebot3_teleop_key.launch and GOT TO OPERATE Turtlebot via Teleoperation/Keyboard.

Also, and as per your recommendation, I executed on Pi:

@.***:~$ rostopic list

/battery_state /clicked_point /cmd_vel /cmd_vel_rc100 /diagnostics /firmware_version /imu /initialpose /joint_states /magnetic_field /motor_power /move_base_simple/goal /odom /reset /rosout /rosout_agg /rpms /scan /sensor_state /sound /tf /tf_static /version_info

and executed the $ rostopic echo /cmd_vel (while running the Teleoperation)

@.***:~$ rostopic echo /cmd_vel linear: x: 0.0 y: 0.0 z: 0.0 angular: x: 0.0 y: 0.0 z: 0.0

Now, I am still having problems when I execute

Hi, What did you get from running the rqt install command below? Were there any errors or warnings?

$ sudo apt-get install ros-melodic-rqt*

Could you try reading the ROS topics from the Raspberry Pi on TurtleBot3 with the command below?

$ rostopic list

I'm not sure why rqt is not working with your PC. I'd recommend to reinstall the desktop full version of ROS and TurtleBot3 packages on your PC.

Some more progress today !!

I was able to execute on PC - @.***:~$ roslaunch turtlebot3_teleop turtlebot3_teleop_key.launch and GOT TO OPERATE Turtlebot via Teleoperation/Keyboard.

Also, and as per your recommendation, I executed on Pi:

@.***:~$ rostopic list

and executed the $ rostopic echo /cmd_vel (while running the Teleoperation)

@.***:~$ rostopic echo /cmd_vel linear: x: 0.0 y: 0.0 z: 0.0 angular: x: 0.0 y: 0.0 z: 0.0

Now, I am still having problems when I execute

Hi @Paulino1956 Could you try below answer and see if it fixes the problem? https://answers.ros.org/question/354039/rqt_virtual_joypluginxml-file-is-missing/

Paulino1956 commented 3 years ago

hello there!

Unfortunately it didn't work! I have executed te instructions

You can add plugin.xml in your directory /opt/ros/melodic/share/rqt_virtual_joy.

Go to rqt_virtual_joy directory.

roscd rqt_vritual_joy

Make file plugin.xml

sudo touch plugin.xml

Edit the plugin.xml file with gedit (or other)

sudo gedit plugin.xml

Copy and paste the contents of the plugin.xml file from the rqt_virtual_joystick github https://github.com/aquahika/rqt_virtual_joystick to your plugin.xml.

edit the file plugin.xml

An example Python GUI plugin to create a great user interface.

@Paulino1956 I'm not familiar with the error you are getting. Could you try uninstall and reinstall ROS?

Paulino1956 commented 3 years ago

Well, I have already done that on both the PC and the Pi. I am using the following image on the Pi: https://www.robotis.com/service/download.php?no=2011 , which was sent by you guys. The original e-manual image for the PI ( http://old-releases.ubuntu.com/releases/18.04.3/ubuntu-18.04.3-preinstalled-server-arm64+raspi3.img.xz) it was disconnecting the Pi from the WI-FI network. However, when I run the e-manual image on the Pi, I was able to run the instruction $rqt.

Thanks fo your help !

@Paulino1956 The TurtleBot3 SBC image that I provided does not support GUI environment, and cannot run rqt on it. Please run the GUI programs such as rqt, rviz, gazebo on the remote PC.

Paulino1956 commented 3 years ago

Dear Friends,

For some reason my RPi3 is not connecting to the internet. I had this issue before, but was able to make it connect using the image you sent me in March (please see below). Today, I used/burned the same image (you sent me in March) again in a new micro SD, followed the same instruction and I was not able to make it work. Same issue: the RPi3 does not connect to the internet ($ifconfig > no ip for the RPi3). Is this image still valid? Anyway I have also download and tried the image available on the e-manual and it did not work either.

Thanks in advance for your support!

The user name is ubuntu and the password is turtlebot

Before using it, you need to open and modify the network settings.

$ sudo nano /etc/netplan/50-cloud-init.yaml Replace the WIFI_SSID and WIFI_PASSWORD for your wifi settings.

Then open the ~/.bashrc file

$ nano ~/.bashrc Modify where ROS_MASTER_URI, ROS_HOSTNAME, TURTLEBOT3_MODEL are defined.

Replace IP_ADDRESS_OF_REMOTE_PC with the IP address of remote pc

Both Remote PC and Raspberry Pi should be connected in the same local network

e.g) export ROS_MASTER_URI=http://192.168.0.10:11311

export ROS_MASTER_URI=http://localhost:11311

Hi @Paulino1956 Recently, the ROS GPG key has been expired which disturbs ROS package update and upgrade. You can follow the instruction below to update the key, but this issue doesn't have to do with the network. https://discourse.ros.org/t/ros-gpg-key-expiration-incident/20669
