Understanding Helix:

Helix boasts 35 degrees of freedom (DoF), offering unparalleled dexterity and autonomy for a humanoid robot. Unlike traditional robots requiring extensive manual programming, Helix dynamically executes complex, long-term tasks using simple natural language instructions. This breakthrough significantly advances the practicality of robots in home settings, where adaptability to diverse objects and unpredictable scenarios is paramount.

Architectural Design: System 1 & System 2:

Helix's architecture mirrors human cognitive processes, drawing inspiration from Kahneman's "Thinking, Fast and Slow" model:

• System 2: The "Big Brain": This 7-billion-parameter Vision-Language Model (VLM) handles high-level reasoning, language comprehension, and visual scene understanding. It translates abstract commands (like "Pick up the desert item") into actionable steps.

• System 1: Precise Action Execution: This 80-million-parameter visuomotor policy ensures rapid, low-level control for precise actions such as grasping and object manipulation, based on System 2's directives. Its compact size enables swift real-time responses.

Both systems operate on low-power embedded GPUs, eliminating reliance on external computing resources and paving the way for commercial viability.

Key Technological Advancements:

• Unified Neural Network: Helix utilizes a single neural network for all behaviors (picking, placing, drawer operation, refrigeration, multi-robot interaction), eliminating the need for task-specific fine-tuning.
• On-the-Fly Behavior Generation: Helix generates intelligent, novel behaviors for unseen objects, minimizing the need for human programming or demonstrations.
• Commercial Readiness: Its embedded GPU architecture ensures immediate real-world applicability without the latency and dependency issues of cloud-based systems.

Demonstration Videos:

Figure AI showcases Helix's capabilities through several compelling videos:

1. Collaborative Grocery Storage: Two Helix-powered robots collaboratively store unfamiliar groceries, demonstrating coordination and adaptability.
2. Object Manipulation: Robots perform various tasks (picking, placing, drawer operation, refrigerator interaction) based on natural language commands.
3. Conceptual Reasoning: Helix interprets abstract commands like "Pick up the desert item," showcasing its ability to connect language to physical actions.

Collaborative Grocery Handling:

This video highlights two robots, controlled by a single Helix instance, efficiently storing diverse, unfamiliar grocery items. Their coordination, including item hand-offs and placement in drawers/containers, is driven by natural language prompts ("Hand the bag of cookies...", "Place it in the open drawer"). This demonstrates Helix's multi-robot collaboration and zero-shot generalization capabilities.

Full Upper-Body Motor Control:

This demonstration showcases Helix's 35-DoF control at 200Hz. The robot smoothly manipulates objects, coordinating its entire upper body (torso, head, wrists, fingers) for optimal reach and precision. This highlights Helix's real-time dexterity and stability, overcoming challenges associated with high-DoF systems.

Language-Guided Object Manipulation:

This video emphasizes Helix's ability to translate high-level commands into precise actions. Responding to "Pick up the desert item," Helix identifies and selects a toy cactus, demonstrating its capacity to link abstract language comprehension to intricate motor control.

Summary:

Figure AI's Helix represents a significant leap forward in humanoid robotics. Its innovative VLA framework, coupled with its dual-system architecture and onboard processing capabilities, enables human-like reasoning and dexterity, making it ideally suited for real-world applications, particularly in home environments. Helix's ability to understand and respond to natural language instructions while handling a wide range of objects without prior training marks a substantial step change in the field of robotics.
