Goat Planner: Robot Control with Multimodal Perception

Goat Planner is a system for planning and executing high-level tasks with a robot. It is mainly design to be used with rove, the CAPRA's student club robot. The system uses a fine-tuned version of LLaMA3 to generate behavior trees for robot task planning and execution and multiple AI pipelines to perform perception, mapping, and voice processing. This work builds on top of multiple recent advances in LLM-based robotics research (e.g. [1,2,3]) and multimodal perception (e.g. [4]).

Demonstration: GoatBrain Video

Overview

Goat Planner bridges the gap between natural language commands and robot execution by:

  • Translating natural language instructions into structured behavior trees
  • Providing real-time execution monitoring and control
  • Supporting both standalone operation and ROS2 integration
  • Offering multiple interfaces (CLI, Web UI) with voice capabilities
  • Integrating with 3D mapping and perception systems
Image Description
Goat Planner web ui The Goat Planner web interface provides an intuitive dashboard for controlling robot behavior. Users can interact with the robot through natural language commands, view the available objects and visualize the current behavior tree.
Goat Planner spatial querying Nature Image Spatial querying capabilities allow the robot to understand and reason about its environment with the help of Shepherd. In this image, the robot is asked to show an picture of the nature, which is corresponding to no real label.
Rove simulation The simulator use is Rove in the aws environment using Gazebo.

Features

  • Language Model Integration: Uses a fine-tuned Ollama model for task planning and behavior tree generation
  • Behavior Tree Generation: Automatically generates plans compatible with BehaviorTree.CPP
  • ROS2 Integration: Distributed node architecture for robotic control
  • Real-time Pipeline: Continuous monitoring and execution of generated plans
  • Web Interface: React-based frontend for user interaction and plan visualization
  • Voice Capabilities: Integrated speech-to-text and text-to-speech functionality
  • 3D Perception: Support for multimodal 3D mapping and scene understanding

TODO

  • Improve shepherd object detection speed
  • Fine-tune goat planner model to improve tree generation
  • Add querying from the web interface
  • Add voice detection (segmentation, wake word, etc.)
  • Add unit tests to make sure the system is working as expected
  • Add more robust logging
  • Perform LLM BLIP querying
  • Monitoring behavior tree execution

Installation
