CHANGELOG

Changelog for package diffbot_base

1.1.0 (2022-03-28)

  • fix: missing subscriber initialization (#54)
  • feat: warn if eStop() is called on mcu
  • Change base config: switch motor pins
  • feat: add callbacks for low level pids on mcu #54 For MCU firmware - Add subscribers for left and right motor pid controllers using diffbot_msgs::PIDStamped custom message
    • Update debug logging message (different formatting)

    - Update PID controller interface (provide proportional_, integral_ and derivative_ values)

  • fix: missing diffbot namespace in test
  • fix: test_encoders.cpp include name
  • feat: add documentation link for unity
  • Merge pull request #42 from joeuser846/motor-defines Use MOTOR_LEFT/RIGHT from diffbot_base_config.h instead of hardcoding pin numbers
  • Fix filenames
  • Use MOTOR_LEFT/RIGHT instead of hardcoding pin numbers
  • Contributors: Franz Pucher, Joe User

1.0.0 (2021-08-13)

  • clean CMakeLists.txt: remove dependency
  • add dependency diffbot_msgs_generate_messages_cpp to build diffbot_msgs before diffbot_base package
  • Refactor: Update interface - Exchange jointStates between high hw intf and low level base controller - Add measured_joint_state publisher in base controller to let high level hw intf subscribe to it
    • Remove encoder publisher (todo consider publishing at low rate)
    • Update docstrings of BaseController
    • Extend interface of diffbot::Encoder class to read jointStates
  • refactor: renamed methods due to interface change: jointStates
  • use new jointState intf between high and low level base
  • make use of diffbot namespace
  • Update base_controller documentation
    • Update BaseController class
    • Add E_STOP_COMMAND_RECEIVED_DURATION define in diffbot_base_config
  • update diffbot_base
    • add diffbot namespace to base_controller library classes
    • update docstrings
    • run rosdoc_lite
    • fix some rosdoc_lite warnings
  • add diffbot_base launch arg to choose robot model (for remo and diffbot)
  • add AngularVelocitiesStamped.h for rosserial
  • remove measured_vel_ publisher in rosserial
  • add low level pid
    • Add pid lib for arduino code
    • make use of pid in base_controller.h
    • update debug logging
    • use ros::time in encoder lib
  • set motor_constant=1 (gain trim model)
  • make use of new diffbot_msgs in hardware interface and base_controller
  • feat: add debug parameter to parameter server add option to enable/disable debug logging of the hw interface
  • refactor base_controller: use ros time instead of millis
  • refactor main.cpp: add base_controller class
    • add base_controller.h with BaseController template class
    • use class publisher and subscriber
    • use BaseController instead of global variables
    • read parameters from parameter server in BaseController
  • add encoder resolution to config header and getter/setter
  • add include guards to encoder.h
  • add base_controller rosserial code using rates
  • fix vector assignment of command velocity in hw intf
  • add tests for motor controllers
  • add compiled rosserial diffbot_msgs
  • add adafruit_feather_wing motor controller class header
  • moved adafruit_feather_wing.cpp to subfolder
  • add adafruit_feather_wing motor controller class
  • add author comment
  • add abstract MotorControllerInterface class
  • remove test_motors.cpp
  • update encoder lib for rosserial
    • add doc strings to encoder.h
    • add ticksToAngle method
    • add angularVelocity method
  • feature: update diffbot_hw_interface
    • add angular wheel joint velocity publisher
    • add new WheelCmd.msg in diffbot_msgs

    - load new hardware related parameters from diffbot_base/config/base.yaml - get hardware related parameters from parameter server in diffbot_hw_interface

    • add gain trim parameters to dynamic reconfigure cfg
  • refactor diffbot_msgs
    • rename Encoder.msg to Encoders.msg
    • update diffbot_pase includes and method signatures
    • update arduino script
    • change diffbot_msgs license to BSDv3
  • add base_controller mcu scripts including tests
  • Update package.xml change license and add rosserial to exec dependencies
  • Contributors: Franz Pucher

0.0.2 (2021-04-30)

  • fix #30: reset encoders after each new launch of hardware interface
  • call reset in encoders setup()
  • add method to check if encoder ticks are published
  • update logging in encoders.ino
  • initialize encoder_ticks_ in hw interface initialize values in encoder_ticks_ member array of hardware interface to zero because receiving meaningful tick values from the microcontroller might take some time. Alleviates problems in #30
  • fix zero time period at control loop start (#30)
  • Contributors: Franz Pucher

0.0.1 (2020-12-22)

  • update diffbot_base to use Encoder msg
  • set control loop rate to 10 Hz
  • add diffbot_msgs as dependency to diffbot_base
  • use queue_size of 10
  • update info output in write() method
  • update initial fpid parameters and adjust their range
  • update info messages with individual pid errors
  • update diffbot_base/launch file to use new diffbot.urdf.xacro
  • add dynamic reconfigure to pid class for f,p,i,d,i_max/min and antiwindup
  • add pid i_max/min and antiwindup to Parameters.cfg
  • add boost to CMakeLists.txt
  • update CMakeLists.txt using dynamic reconfigure
  • add dynamic_reconfigure to package.xml
  • add Parameters.cfg for feed forward gain
  • reset pid error and cmd values in case setpoint and p_error is zero: avoids non-vanishing i_error
  • tune pid and feed forward gains
  • fix major bug: prev_time not updated
  • refactor pid to enable dynamic reconfigure for both motors
  • add debug output logging messages to pid class and enable dynamic reconfigure - needs param for more than one pid
  • let PID inherit from control_toolbox::Pid
  • add pid controller for motors from ros control toolbox
  • add pid.cpp in cmake
  • Update version, mail and license
  • fix compile error and runtime errors due to dynamic reconfigure using initPid instead of setGains and tune PID values (P=10.0)
  • Update README.md and add comments to code
  • move packages from ros/src to repository toplevel folder
  • Contributors: Franz Pucher
