rm_calibration_controllers

Overview​

Since the zero point of some motors will change after power off, rm_calibration_controller will move at a certain speed after it is started until motors reach the mechanical limit, and motors position will be reset to zero.

Keywords: calibration, ROS, position.

The package has been tested under ROS Indigo, Melodic and Noetic on respectively Ubuntu 18.04 and 20.04. This is research code, expect that it changes often and any fitness for a particular purpose is disclaimed.

Hardware interface type​

  • EffortJointInterface Used to send effort command to target joint to make it reach the calibration speed.
  • ActuatorExtraInterface Used to obtain the information of the target actuators offset, current position, the state of the whether it is stopped and the state of whether it is calibrated.

Installation​

Installation from Packages​

To install all packages from the this repository as Debian packages use

sudo apt-get install ros-noetic-calibration-controllers

Or better, use rosdep:

sudo rosdep install --from-paths src

Parameters​

  • search_velocity (double)

    The joint angular velocity of calibrating.

  • threshold (double)

    This is angular velocity threshold. When the real time angular velocity of target motor lower than threshold, and last for a while, it can switch CALIBRATED from MOVING.
