General

Warning
This release required changes in the low level of the Built-in Computers operating system.

  • Raspberry Pi-specific dependencies were removed and replaced with general, standard Linux libraries.
  • Some of the code was rewritten in C++ to improve efficiency.
  • Hardware access to the nodes was modified to allow for strict confinement of containerized applications.
  • Added RViz plugin visualizing the Bumper Lights animation. See rviz_textured_quads.

panther_battery

New Features

  • The robot will not find itself charging when the charger is not connected to a wall socket.
  • Extended logging of battery state.

API Changes

  • front_light_link and rear_light_link were renamed to front_bumper_link and rear_bumper_link.
  • front_light_link and rear_light_link are now at the height of the Bumper Lights LED panels and are meant to be reference frames for the animation images.

Bug fixes

  • Meshes are now resolved by package name and not by the local file path, evaluated by Xacro.

  • Power-related errors and warnings to motor drivers are now suppressed if motors are powered off.

Backend Changes
