• Transformations: Concept, Implementation
• New message: PointCloud2
• ROS2 parameters + remapping
• XML launch files
• Fun: Steer the robot
• New message: Twist

• Concept: State Estimation via
  • Wheel Odometry
  • IMU
  • LiDAR
  • Camera
• Fusion
  • Kalman-Filter
  • robot_localization-package
• Start a robot! In reality.
• Tool: tmux
• Mapping
