g_compensation

  • This repository contains the g_compensator ROS node.

  • The node subscribes to a Wrenched Stamped topic performes a non-dynamical gravitation compensation and publishes another Wrenched Stamped topic

  • The correction is based on the parameter mass in kg, com_frame (center of mass) as tf-frame id, gravity_frame (world frame) as tf-frame id with gravity pointing in negative z-direction with g=9.81. All parameters are to be set on the parameter-server

  • All calculations are based on PyKDL and tf2

  • A rosservice /tare can be called to tare in the current pose.
