The Future of Human-AI Interaction
Agent-L is more than a robot — it's a living demonstration of embodied artificial intelligence. Designed in Shaper3D and powered by Raspberry Pi 5, it blends expressive mechanical design with modern AI intelligence.
Anatomy of a Character
To understand how Agent-L comes to life, we must look inside. Layer by layer, we reveal the systems that create its form, movement, and intelligence.
The Skeleton
The core of Agent-L is a precision-engineered mechanical system designed in Shaper3D. Its structure houses a 5-servo system that translates digital commands into lifelike, physical motion.
3D-Printed Shell
The face and skull providing the character's distinctive form
Core Mechanical Frame
The chassis supporting all internal components with precision
Precision Servos
The muscles that drive all movement with accuracy and control
5-Servo Expression System
Five independent servos work in concert to give Agent-L a wide range of expression, crucial for creating a sense of presence and engagement.
Eye Movement & Gaze Control
Allows the head to track objects and simulate natural eye contact
Mouth Articulation
Synchronizes with speech for realistic communication
Neck Rotation
Smooth side-to-side motion to engage with its environment
Future-Ready Design
Allows for future upgrades like eyelids and a tilt axis
Precision-Engineered Manufacturing
Agent-L is crafted using advanced 3D printing technology, bringing digital designs into physical reality with exceptional detail and accuracy.
Embodied AI Architecture
A reference design for mobile-controlled robotics with real-time AI voice and expression. The architecture separates fast, local motion control from cloud-scale intelligence.
