Open Manipulator Fails BringUP

[gandradeng]

Hi everyone, I'm having this errors (exception) when trying to bringup the turtlebot3 with the open manipulator: $ ros2 launch turtlebot3_manipulation_bringup hardware.launch.py [INFO] [launch]: All log files can be found below /home/dali/.ros/log/2023-07-01-20-56-48-983432-dali-turtlebot-10821 [INFO] [launch]: Default logging verbosity is set to INFO [ERROR] [launch]: Caught exception in launch (see debug for traceback): executable '[<launch.substitutions.text_substitution.TextSubstitution object at 0xffff8f854100>]' not found on the PATH

Data: Turtlebo3 with OpenManipulator X, Humble, Ubuntu 22.04, Raspberry Pi 4.

Hi, Could you try below command on 'turtlebot3_ws' using Terminal?

$ source install/setup.bash

[ozanaki]

I have the same issue too. @yeongkyuyoon Sourcing the install/setup.bash did not fix the issue.

ROS2 Humble / Ubuntu 22.04 Server / Raspberry Pi 4 / Turtlebot3 Waffle Pi with Manipulator.

ubuntu@wafflepi:~/turtlebot3_ws$ source install/setup.bash ubuntu@wafflepi:~/turtlebot3_ws$ ros2 launch turtlebot3_manipulation_bringup hardware.launch.py [INFO] [launch]: All log files can be found below /home/ubuntu/.ros/log/2023-07-13-16-58-41-633216-wafflepi-1236 [INFO] [launch]: Default logging verbosity is set to INFO [ERROR] [launch]: Caught exception in launch (see debug for traceback): executable '[<launch.substitutions.text_substitution.TextSubstitution object at 0xffffbafb6c50>]' not found on the PATH ubuntu@wafflepi:~/turtlebot3_ws$

@ozanaki Perhaps some dependency packages are not installed, resulting in errors when executing the launch file. I identified all the missing packages in the ROS2 Foxy version and conducted tests accordingly.

It is assumed that the Humble version also encounters a similar problem. Please install the following dependency packages from the Humble distro.

sudo apt install ros-foxy-hardware-interface sudo apt install ros-foxy-xacro sudo apt install ros-foxy-imu-sensor-broadcaster sudo apt install ros-foxy-diff-drive-controller sudo apt install ros-foxy-position-controllers sudo apt install ros-foxy-gripper-controllers sudo apt install ros-foxy-joint-state-broadcaster sudo apt install ros-foxy-joint-trajectory-controller sudo apt install ros-foxy-controller-manager

and run sudo apt-get update && sudo apt-get dist-upgrade.

[ozanaki]

@yeongkyuyoon I have installed these packages for Humble as you suggested. This error message has disappeared, the manipulator has gone to the start position while bringing up.

sudo apt install ros-humble-hardware-interface sudo apt install ros-humble-xacro sudo apt install ros-humble-imu-sensor-broadcaster sudo apt install ros-humble-diff-drive-controller sudo apt install ros-humble-position-controllers sudo apt install ros-humble-gripper-controllers sudo apt install ros-humble-joint-state-broadcaster sudo apt install ros-humble-joint-trajectory-controller sudo apt install ros-humble-controller-manager

But this time some different error messages appeared on the terminal as [ERROR] [DynamixelSDKWrapper] [TxRxResult] There is no status packet! and [ros2_control_node-1] *** stack smashing detected ***: terminated seems not related to this issue. I just proceed to another issue :)

Thank you for your help

[gandradeng]

I was able to solve the original issue but typing (at tb3) sudo apt install ros-humble-launch-*. But then another problem came through bring up:
[ros2_control_node-1] [ERROR] [DynamixelSDKWrapper] [TxRxResult] There is no status packet!

[yeongkyuyoon]

@ozanaki @gandradeng Hi, I guess it's a problem with OpenCR's firmware. What firmware are you using? Have you installed it according to the guidelines in the E-manual? Try the directions below, and let me know.

[TurtleBot3 SBC] Download the OpenCR firmware file on Raspberry Pi (SBC) and upload the correct firmware with the following commands. $ export OPENCR_PORT=/dev/ttyACM0 $ export OPENCR_MODEL=turtlebot3_manipulation $ rm -rf ./opencr_update.tar.bz2 $ wget https://github.com/ROBOTIS-GIT/OpenCR-Binaries/raw/master/turtlebot3/ROS2/latest/opencr_update.tar.bz2 $ tar -xvf opencr_update.tar.bz2 $ cd ./opencr_update $ ./update.sh $OPENCR_PORT $OPENCR_MODEL.opencr

[gandradeng]

Hi, @yeongkyuyoon! I did exactly as in E-manual and until now the open manipulator is not working.

[ozanaki]

@yeongkyuyoon I am exactly following the instructions in the manual including setting up the OpenCR. I installed the manipulation package on freshly installed ROS2 Humble on Ubuntu 22.04 on Raspberry Pi 4 (waffle pi with manipulator) described as in the manual https://emanual.robotis.com/docs/en/platform/turtlebot3/manipulation/#software-setup.

Here is the ssh terminal output screen after applying the bringup command $ ros2 launch turtlebot3_manipulation_bringup hardware.launch.py:

Hi, I've got the same problem as @ozanaki. Did anybody manage to solve it? I suppose it is something connected with OpenCR software.
