What it can do

Written by Robotheca from the project's documents.

  • Maps a room using a 360-degree laser distance sensor, using ROS2-based software.
  • Drives autonomously (self-driving), using ROS2-based software.
  • Designed as a 200mm round, 3D-printable pet robot compatible with the Kaia.ai software platform.
  • Character and skills coding is listed as work in progress.
