Roomblock fail to open port /dev/roomba #14

rwayong · 2019-11-26T10:12:17Z

Hi,

I installed roomblock according to the instructions (sudo apt-get install ...).

First I launched roscore, then on separate terminal, I launched roslaunch roomblock_bringup roomblock.launch.
It gave me error that say it cannot bind to /dev/rplidar. So I remapped my rplidar serial port by executing "create_udev_rules.sh" located at "/catkin_ws/src/roomblock/roomblock_bringup/scripts". It worked for my rplidar as shown below.

pi@pi-desktop:~$ ls -l /dev | grep ttyUSB
lrwxrwxrwx  1 root root           7 11月 26 10:25 rplidar -> ttyUSB0
crwxrwxrwx  1 root dialout 188,   0 11月 26 10:29 ttyUSB0
crwxrwxrwx  1 root dialout 188,   1 11月 26 10:25 ttyUSB1

However, my roomba serial port (ttyUSB1) is not remapped. I checked my roomba vendor and product id,

pi@pi-desktop:~$ lsusb
Bus 001 Device 008: ID 067b:2303 Prolific Technology, Inc. PL2303 Serial Port
Bus 001 Device 006: ID 10c4:ea60 Cygnal Integrated Products, Inc. CP210x UART Bridge / myAVR mySmartUSB light
Bus 001 Device 007: ID 05ac:021f Apple, Inc. Aluminum Mini Keyboard (JIS)
Bus 001 Device 005: ID 05ac:1005 Apple, Inc. 
Bus 001 Device 004: ID 05ac:0304 Apple, Inc. Mighty Mouse [Mitsumi, M1152]
Bus 001 Device 003: ID 0424:ec00 Standard Microsystems Corp. SMSC9512/9514 Fast Ethernet Adapter
Bus 001 Device 002: ID 0424:9514 Standard Microsystems Corp. SMC9514 Hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

I found that my vendor and product id setting in roomba.rules didn't match, so I changed it to

KERNEL=="ttyUSB*", ATTRS{idVendor}=="067b", ATTRS{idProduct}=="2303", MODE:="0777", SYMLINK+="roomba"

Then, I executed "delete_udev_rules.sh" to reset my udev rules and once again I executed "create_udev_rules.sh".
Nevertheless, when I launched > roslaunch roomblock_bringup roomblock.launch, it gave me error as below.

pi@pi-desktop:~$ roslaunch roomblock_bringup roomblock.launch

Can somebody help me with this problem? I'm still new to ROS, so maybe I'm looking at the wrong places and I really appreciate if someone can point out where the problem is.

Thanks!

Initial post on ROS Answers: Roomblock fail to open port /dev/roomba due to failure in remapping roomba serial port.

7675t · 2019-11-30T13:01:57Z

Sorry to be late to respond. Right, the udev rules depends on the hardware, so if you are using different serial-USB adapter for Roomba, you have to change PID and UID (Yes, it may not be good design...).

Please make sure your /dev/roomba point to your serial-USB device for Roomba. If not, what happens if you do it manually like follows?

$ sudo chmod 777 /dev/ttyUSB1
$ ln -s /dev/ttyUSB1 /dev/roomba

In addition, please notice you have to restart udev daemon like

$ sudo service udev restart

and make sure you re-plug the USB device after change your udev rule files.

rwayong · 2019-12-05T06:09:33Z

Thanks for your reply. I tried to set the serial port manually and it worked.
However, when I tried to move my roomba using my keyboard, it didn't move. In the terminal that launch roslaunch roomblock_bringup roomblock.launch, it gave me a warn "Failed to read sensor package. 5 retries left." as below.

I really thankful if you can help me with this problem. Thanks!

7675t · 2019-12-16T14:29:43Z

Please confirm your Roomba is power on. You need to power on by pushing the power button.

rwayong · 2019-12-17T05:20:40Z

Please confirm your Roomba is power on. You need to power on by pushing the power button.

Yeah, I pushed the power button and the green light appeared. Then, when I roslaunch roomblock_bringup roomblock.launch and I heard "beep" sound from the roomba.
Nevertheless, I still can't move my roomba by teleop keyboard.

The commands that I ran are as below.

roscore
roslaunch roomblock_bringup roomblock.launch
rosrun teleop_twist_keyboard teleop_twist_keyboard.py
roslaunch roomblock_mapping gmapping.launch

And also, the rviz showed error on the laser scan as the attached picture.

7675t · 2019-12-18T13:41:36Z

OK, don't jump on to SLAM, please check it step by step.

If you heard a short beep sound, I guess the communication with the Roomba should be OK.
To confirm this, check if create_node publishes the sensor topic on "mobile_base/sensors/core" by using rostopic echo
/joint_states should be published
/odom should be published too.
Your rviz screen capture says some error on LaserScan. Can you show it?
If above checks are all positive, check if the /cmd_vel is really working by publish the command as:

rostopic pub /cmd_vel geometry_msgs/Twist "linear:
  x: 0.1
  y: 0.0
  z: 0.0
angular:
  x: 0.0
  y: 0.0
  z: 0.0"

I'm sorry for the late reply and happy new year bro :)

OK, don't jump on to SLAM, please check it step by step.

If you heard a short beep sound, I guess the communication with the Roomba should be OK.

To confirm this, check if create_node publishes the sensor topic on "mobile_base/sensors/core" by using rostopic echo

/joint_states should be published

/odom should be published too.

So after I run roscore and roslaunch roomblock_bringup roomblock.launch, I heard the short beep sound. First I ran rostopic list. The results is given below.

pi@pi-desktop:~$ rostopic list
/cmd_vel
/diagnostics
/joint_states
/mobile_base/sensors/core
/odom
/robot_pose_ekf/odom_combined
/rosout
/rosout_agg
/scan
/tf
/tf_static
/turtlebot_node/parameter_descriptions
/turtlebot_node/parameter_updates

Then I ran rostoic echo mobile_base/sensors/core and the results is shown below.

Your rviz screen capture says some error on LaserScan. Can you show it?

I attached the screenshot that shows the error on LaserScan. In case you can't see it, I uploaded it to gdrive.

If above checks are all positive, check if the /cmd_vel is really working by publish the command as:
rostopic pub /cmd_vel geometry_msgs/Twist "linear:
  x: 0.1
  y: 0.0
  z: 0.0
angular:
  x: 0.0
  y: 0.0
  z: 0.0" 

Since /joint_states, /odom and mobile_base/sensors/core seems to be published, I ran the /cmd_vel. However, nothing happens and the clean button of the roomba starts blinking. I use Roomba 642 and the connector is a simple USB cable as shown below.

I hoped you can help me with these problems. Thank you very much.

7675t · 2020-01-11T14:20:27Z

Very strange... It seems the ROS node is receiving data and sending commands successfully.
To my knowledge, it should work correctly. Anything on /diagnostics ?

Can you check the sensors/core message when the cmd_vel is given?

requested_velocity: 0
requested_radius: 0

These value should be changed.

rwayong · 2020-01-13T03:52:02Z

After I published the cmd_vel, my /diagnostics looks like this.

I can't find any problem in your information so far...
Can you do roslaunch with --screen option? It may print more information.

roslaunch roomblock_bringup roomblock.launch --screen

So, after I ran roslaunch roomblock_bringup roomblock.launch --screen, and I got a warning regarding Join state as below.

I think the warnings are not the cause of the problem. They are just warnings.

Sorry, I have ran out of my ideas for shooting the trouble here.
I suggest some ways to dig it .

here is the line to send cmd_vel to roomba. Insert debug print to check if something goes wrong
Try create_autonomy package to control your roomba. If it doesn't works, problem may be your roomba-side.

It may some hardware problems. We've tried this turtlebot_create package with at least four roombas(500 and 600 series) and haven't experienced problem like this.

Good luck,

Thanks for you time. I'll try roomblock package on different roomba.
Last question, can you tell me the environment that you used when testing the turtlebot_create package or roomblock package? Like, the model number of roomba (642 or something), raspberry pi and its OS, etc.
