adi_tmcl

adi_tmcl (previously tmcl_ros2) is the official ROS2 Driver for ADI Trinamic Motor Controllers (TMC) that uses Trinamic Motion Control Language (TMCL) protocol.

Background

  • Supported TMC boards: TMCM-1636, TMCM-1617, TMCM-1241, TMCM-1260, TMCM-6214
  • Supported communication interface and interface driver: CAN (SocketCAN)
  • Supported ROS2 and OS distro: Humble (Ubuntu 22.04)
  • Supported platform: Intel x86 64-bit (amd64)

Software Dependencies

Assumptions before building this package: * Installed ROS2 Humble. If not, follow these steps. * Setup workspace (with workspace folder named as "ros2_ws"). If not, follow these steps.

Clone

In the website: 1. Make sure that the branch dropdown is set to "humble". 2. Click the "Clone" or "Code" button, then copy the SSH or HTTPS link (eg, "*.git").

In a terminal, do the following:

$ cd ~/ros2_ws/src
$ git clone <copied SSH o HTTPS link here> adi_tmcl  #clones repo to "adi_tmcl" directory name

Build

########## [TERMINAL 1] ##########
# Do proper exports first:
## $ source /opt/ros/<ROS2 Version>/setup.bash
$ source /opt/ros/humble/setup.bash 

# Resolve any dependencies
$ cd ~/ros2_ws
$ rosdep install -i --from-path src --rosdistro humble -y

# Build
$ colcon build
## To clean first before building, you may run the following instead:
## $ colcon build --cmake-clean-first

:memo: Note: It is recommended that 1 terminal is dedicated to building the package/workspace to avoid complex issues as mentioned in ROS2 Source the overlay

Pre-Launch (One-time per setup)

If it's the first time to use the set of motors for the TMC that you are using, it is required to calibrate and tune the PID settings of the motors first.

Do the calibrations/tuning by downloading and using TMCL-IDE.

BLDC Motors

Calibrate the motors

For a run-through/tutorial of how the calibration is done in the TMCL-IDE via its Wizard Pool feature, check this link.

Tune the PI settings of the motors

For a run-through/tutorial of how the PI tuning is done in the TMCL-IDE via its PI Tuning feature, check this link.

:memo: Note: For all the calibration and tuning done, store all the parameters set from TMCL_IDE on the board's EEPROM. Do this by doing any of the following: - Clicking the "Store Parameter" under Settings of each axis - Using STAP (Store Axis Parameters) command from Direct Mode - Creating and uploading a TMCL Program, and enabling the "auto start mode" under SGP (Set Global Parameter) command from Direct Mode - - :memo: Note: Some boards don't have "auto start mode", so in such a case, use the other options to store the parameters.

Stepper Motors

Calibrate the motors

For a run-through/tutorial of how the calibration is done in the TMCL-IDE via its Wizard Pool feature, check this link.

:memo: Note: For all the calibration and tuning done, store all the parameters set from TMCL_IDE on the board's EEPROM. Do this by: - Creating and uploading a TMCL Program, and enabling the "auto start mode" under SGP (Set Global Parameter) command from Direct Mode

Pre-Launch (One-time)

Initialize CAN

:memo: Note: This script automatically brings-up CAN upon boot. Do this step only once.

To proceed, first make the script executable (do this only once as this change persists even after power-off):

$ cd ~/ros2_ws/src/adi_tmcl/scripts # or ~/ros2_ws/src/<repo directory>/scripts
$ chmod +x CAN_init.sh

Execute the script:

# To know more about the usage
$ sudo ./CAN_init.sh -h
# Usage
$ sudo ./CAN_init.sh -i <communication interface name> -b <bitrate>
# Example: can0 as communication interface name and 1000KBPS bitrate
$ sudo ./CAN_init.sh -i can0 -b 1000000

Where: - CAN communication interface name is the interface used between the PC and the TMC (accepted values: can0 - can255) - bitrate is the rate of communication interface (accepted values: 20000, 50000, 100000, 125000, 250000, 500000, 1000000)

:memo: Note: The above mentioned accepted values are a range, though the user still needs to check the actual TMC's datasheet on the applicable range. Additionally, the bitrate set here must be the same bitrate set into the the TMC as the Global Parameter "CAN bit rate".

De-initialize CAN

:memo: Note: This script disables the automatic bring-up of CAN upon boot.

To proceed, first make the script executable (do this only once as this change persists even after power-off):

$ $ cd ~/ros2_ws/src/adi_tmcl/scripts # or ~/ros2_ws/src/<repo directory>/scripts
$ chmod +x CAN_deinit.sh

Execute the script:

# To know more about the usage
$ sudo ./CAN_deinit.sh -h
# Usage
$ sudo ./CAN_deinit.sh -i <communication interface name>
# Example: can0 as communication interface name
$ sudo ./CAN_deinit.sh -i can0

Where: - communication interface is the interface used between the PC and the TMC (accepted values: can0 - can255)

Launch

########## [TERMINAL 2] ##########
# Do proper exports first:
$ cd ~/ros2_ws
$ source install/setup.bash

# Launch
$ ros2 launch adi_tmcl tmcm_1636.launch.py

# Launch with DEBUG logs
$ ros2 launch adi_tmcl tmcm_1636.launch.py log_level:=DEBUG

:memo: Note: This should be a different terminal from the one you used when building to avoid complex issues as mentioned in ROS2 Source the overlay

Nodes

tmcl_ros2_node

:memo: Note: For those with in the topic names, these are ideally the motor number. For example, if there are 2 motors used, there should be two published topics for tmc_info, specifically /tmc_info_0 for motor 0 and then /tmc_info_1 for motor 1.

Published topics

These are the default topic names, topic names can be modified as a ROS parameter.

    • The output contains raw data (velocity = rpm, position = units) from the board. Do not expect same unit from the publisher.
  • /tmcl_gap_all (adi_tmcl/srv/TmcGapAll)
    • Get all Axis Parameter values
  • /tmcl_ggp_all (adi_tmcl/srv/TmcGgpAll)
    • Get all Global Parameter values

Parameters

:memo: Notes: - If any of these parameters are not set/declared, default values will be used. - To know more details about each parameter, you can execute $ ros2 param describe <node> <parameter>

Communication Interface Parameters
  • comm_interface (int, default: 0)
    • Interface used between the PC and the TMC (where 0 = CAN)

Quick Tests

Test Velocity Mode

To do a quick test of Velocity Mode, there is a fake velocity script that the user can run. Idea is, this script will send Velocity commands (as a ROS topic), then the first motor should be expected to: 1. Increase velocity every 3secs, clockwise (in m/s: 3, 6, 9) 2. Stop for 5secs 3. Increase velocity every 3secs, counter-clockwise (in m/s: -3, -6, -9) 4. Stop for 5secs

To proceed with the test, execute these following commands on three (3) different terminals (in sequence):

:memo: Note: Assuming that the package was built in Terminal 1 and Initialize CAN is already done on Terminal 1.

Terminal 2 Terminal 3 Terminal 4 
$ cd ~/ros2_ws/ 
$ source /opt/ros/humble/setup.bash 
$ source install/setup.bash 
$ ros2 launch adi_tmcl tmcm_1636.launch.py
 
$ cd ~/ros2_ws/ 
$ source /opt/ros/humble/setup.bash 
$ source install/setup.bash 
$ ros2 topic echo /tmc_info_0
 
$ cd ~/ros2_ws/src/adi_tmcl/scripts 
$ sudo chmod 777 fake_cmd_vel.sh 
$ ./fake_cmd_vel.sh

Monitor the velocity of the first motor (watch out for velocity value at Terminal 3).

:memo: Notes: - Terminals 3 and 4 are best viewed side-by-side. - You may Ctrl-C the command in Terminal 2 and 3 once you're done. - The command in Terminal 4 auto-stops by itself.

Test Position Mode

To do a quick test of Position Mode, there is a fake position script that the user can run. Idea is, this script will send Position commands (as a ROS topic), then the first motor should be expected to: 1. Rotate 360 degrees (clockwise) every 5 secs, 3 times 2. Stop for 5secs 3. Rotate 360 degrees (counter-clockwise) every 5 secs, 3 times 4. Stop for 5secs

To proceed with the test, execute these following commands on three (3) different terminals (in sequence):

:memo: Note: Assuming that the package was built in Terminal 1 and Initialize CAN is already done on Terminal 1.

Terminal 2 Terminal 3 Terminal 4 
$ cd ~/ros2_ws/ 
$ source /opt/ros/humble/setup.bash 
$ source install/setup.bash 
$ ros2 launch adi_tmcl tmcm_1636.launch.py
 
$ cd ~/ros2_ws/ 
$ source /opt/ros/humble/setup.bash 
$ source install/setup.bash 
$ ros2 topic echo /tmc_info_0
 
$ cd ~/ros2_ws/src/adi_tmcl/scripts 
$ sudo chmod 777 fake_cmd_pos.sh 
$ ./fake_cmd_pos.sh

Monitor the position of the first motor (watch out for position value at Terminal 3).

:memo: Notes: - Terminals 3 and 4 are best viewed side-by-side. - You may Ctrl-C the command in Terminal 2 and 3 once you're done. - The command in Terminal 4 auto-stops by itself.

Test Torque Mode

To do a quick test of Torque Mode, there is a fake torque script that the user can run. Idea is, this script will send Torque commands (as a ROS topic), then the first motor should be expected to: 1. Rotate for 5 secs, with torque = 300 2. Stop for 5secs 3. Rotate for 5 secs again, with torque = 300

To proceed with the test, execute these following commands on three (3) different terminals (in sequence):

:memo: Note: Assuming that the package was built in Terminal 1 and Initialize CAN is already done on Terminal 1.

Terminal 2 Terminal 3 Terminal 4 
$ cd ~/ros2_ws/ 
$ source /opt/ros/humble/setup.bash 
$ source install/setup.bash 
$ ros2 launch adi_tmcl tmcm_1636.launch.py
 
$ cd ~/ros2_ws/ 
$ source /opt/ros/humble/setup.bash 
$ source install/setup.bash 
$ ros2 topic echo /tmc_info_0
 
$ cd ~/ros2_ws/src/adi_tmcl/scripts 
$ sudo chmod 777 fake_cmd_trq.sh 
$ ./fake_cmd_trq.sh

Monitor the torque of the first motor (watch out for torque value at Terminal 3).

:memo: Notes: - Terminals 3 and 4 are best viewed side-by-side. - You may Ctrl-C the command in Terminal 1 and 2 once you're done. - The command in Terminal 4 auto-stops by itself.

Where: - "ROS version" is the user's actual ROS version

Then:

$ cd ~/catkin_ws/
$ catkin_make clean
$ catkin_make
$ source devel/setup.bash

Pre-Launch (One-time per setup)

Pre-Launch (One-time)

Initialize CAN

:memo: Note: This script automatically brings-up CAN upon boot. Do this step only once.

To proceed, first make the script executable (do this only once as this change persists even after power-off):

$ cd ~/catkin_ws/src/adi_tmcl/scripts # or $ cd ~/catkin_ws/src/<repo directory>/scripts
$ chmod +x CAN_init.sh

Execute the script:

$ sudo ./CAN_init.sh <communication interface> <bitrate>

Where: - communication interface is the interface used between the PC and the TMC (accepted values: 0 -255) - bitrate is the rate of communication interface (accepted values: 20000, 50000, 100000, 125000, 250000, 500000, 1000000)

:memo: Note: The above mentioned accepted values are a range, though the user still needs to check the actual TMC's datasheet on the applicable range. Additionally, the bitrate set here must be the same bitrate set into the the TMC as the Global Parameter "CAN bit rate".

For example, to initialize CAN with can0 as communication interface and 1000KBPS bitrate:

$ sudo ./CAN_init.sh 0 1000000

De-initialize CAN

:memo: Note: This script disables the automatic bring-up of CAN upon boot.

To proceed, first make the script executable (do this only once as this change persists even after power-off):

$ cd ~/catkin_ws/src/adi_tmcl/scripts # or $ cd ~/catkin_ws/src/<repo directory>/scripts
$ chmod +x CAN_deinit.sh

Execute the script:

$ sudo ./CAN_deinit.sh <communication interface>

Where: - communication interface is the interface used between the PC and the TMC (accepted values: 0 -255)

For example, to de-initialize CAN with can0 as communication interface:

$ sudo ./CAN_deinit.sh 0

Quick Tests

Test Velocity Mode

To do a quick test of Velocity Mode, there is a fake velocity script that the user can run. Idea is, this script will send Velocity commands (as a ROS topic), then the first motor should be expected to: 1. Increase velocity every 3secs, clockwise (in m/s: 3, 6, 9) 2. Stop for 5secs 3. Increase velocity every 3secs, counter-clockwise (in m/s: -3, -6, -9) 4. Stop for 5secs

To proceed with the test, execute these following commands on three (3) different terminals (in sequence):

:memo: Note: Assuming that Initialize CAN is already done on Terminal 1.

Terminal 1 Terminal 2 Terminal 3 
$ cd ~/catkin_ws/ 
$ source /opt/ros/noetic/setup.bash 
$ source devel/setup.bash 
$ roslaunch adi_tmcl tmcm_1636.launch
 
$ cd ~/catkin_ws/ 
$ source /opt/ros/noetic/setup.bash 
$ source devel/setup.bash 
$ rostopic echo /tmcm1/tmc_info_0
 
$ cd ~/catkin_ws/src/adi_tmcl/scripts 
$ sudo chmod 777 fake_cmd_vel.sh 
$ ./fake_cmd_vel.sh

Monitor the velocity of the first motor (watch out for velocity value at Terminal 2).

:memo: Notes: - Terminals 2 and 3 are best viewed side-by-side. - You may Ctrl-C the command in Terminal 2 once you're done. - The command in Terminal 3 auto-stops by itself.

Test Position Mode

To do a quick test of Position Mode, there is a fake position script that the user can run. Idea is, this script will send Position commands (as a ROS topic), then the first motor should be expected to: 1. Rotate 360 degrees (clockwise) every 5 secs, 3 times 2. Stop for 5secs 3. Rotate 360 degrees (counter-clockwise) every 5 secs, 3 times 4. Stop for 5secs

To proceed with the test, execute these following commands on three (3) different terminals (in sequence):

:memo: Note: Assuming that Initialize CAN is already done on Terminal 1.

Terminal 1 Terminal 2 Terminal 3 
$ cd ~/catkin_ws/ 
$ source /opt/ros/noetic/setup.bash 
$ source devel/setup.bash 
$ roslaunch adi_tmcl tmcm_1636.launch
 
$ cd ~/catkin_ws/ 
$ source /opt/ros/noetic/setup.bash 
$ source devel/setup.bash 
$ rostopic echo /tmcm1/tmc_info_0
 
$ cd ~/catkin_ws/src/adi_tmcl/scripts 
$ sudo chmod 777 fake_cmd_pos.sh 
$ ./fake_cmd_pos.sh

Monitor the position of the first motor (watch out for position value at Terminal 2).

:memo: Notes: - Terminals 2 and 3 are best viewed side-by-side. - You may Ctrl-C the command in Terminal 2 once you're done. - The command in Terminal 3 auto-stops by itself.

Test Torque Mode

To do a quick test of Torque Mode, there is a fake torque script that the user can run. Idea is, this script will send Torque commands (as a ROS topic), then the first motor should be expected to: 1. Rotate for 5 secs, with torque = 300 2. Stop for 5secs 3. Rotate for 5 secs again, with torque = 300

To proceed with the test, execute these following commands on three (3) different terminals (in sequence):

:memo: Note: Assuming that Initialize CAN is already done on Terminal 1.

Terminal 1 Terminal 2 Terminal 3 
$ cd ~/catkin_ws/ 
$ source /opt/ros/noetic/setup.bash 
$ source devel/setup.bash 
$ roslaunch adi_tmcl tmcm_1636.launch
 
$ cd ~/catkin_ws/ 
$ source /opt/ros/noetic/setup.bash 
$ source devel/setup.bash 
$ rostopic echo /tmcm1/tmc_info_0
 
$ cd ~/catkin_ws/src/adi_tmcl/scripts 
$ sudo chmod 777 fake_cmd_trq.sh 
$ ./fake_cmd_trq.sh

Monitor the torque of the first motor (watch out for torque value at Terminal 2).

:memo: Notes: - Terminals 2 and 3 are best viewed side-by-side. - You may Ctrl-C the command in Terminal 2 once you're done. - The command in Terminal 3 auto-stops by itself.
