Types of AI Agents
Different “agent types” emerge depending on their role in the system:
- Perception Agents
- Use cameras (RGB, depth, motion capture) to detect body position, angles, velocity.
- Models: pose estimation (e.g., MediaPipe, OpenPose, DeepLabCut).
- Analysis Agents
- Take raw perception data → calculate biomechanics (joint angles, timing, force approximations).
- Compare performance to “ideal form” models (pro athlete libraries, coaching heuristics).
- Decision/Feedback Agents
- Translate analysis into plain language: “Your release point is too low; raise elbow by ~10°.”
- Provide real-time corrective cues (visual overlay, AR coach, haptic feedback).
- Knowledge Agents
- Build and manage the knowledge base — library of thousands of “reference throws” tagged with fundamentals.
- Train continuously from more samples.
- Interface/Engagement Agents
- Handle user experience: dashboards, mobile apps, AR glasses, or web portals.
- Tailor feedback depending on audience (player, coach, scout, fan).
Hardware Requirements
You’ll need a physical setup to capture reliable data:
- Cameras
- High-frame-rate RGB cameras (120–240fps) for form breakdown.
- Depth cameras (Intel RealSense, Azure Kinect, iPhone LiDAR) for 3D skeleton mapping.
- Optional: motion capture suits or markers for high-precision biomechanics (expensive, ~$20k–$150k).
- Edge Computing (for real-time feedback)
- GPU-enabled local compute (NVIDIA Jetson, small RTX servers).
- Runs pose estimation + first-pass analysis before sending data to cloud.
- Networking
- Reliable Wi-Fi or 5G if streaming data live.
- Buffering system to prevent lag in real-time coaching.
Software / Data Pipeline
Here’s the flow of how an AI Agent would process:
- Capture Layer
- Cameras capture 2D/3D skeletal frames.
- Pre-processing filters noise.
- Pose Estimation Layer
- OpenPose/MediaPipe generates 3D skeleton (joint coordinates).
- Time-series data of movement.
- Biomechanics Analysis Layer
- Calculate joint angles, angular velocity, stride length, hip-shoulder separation, etc.
- Compare against thresholds for “good form.”
- AI Feedback Layer
- Machine learning trained on thousands of throws.
- Generates specific coaching advice: “arm lag detected,” “foot plant early.”
- UI/UX Layer
- Cloud dashboards for reviewing sessions.
- Real-time overlay on video (like telestration).
- AR/VR extension for immersive coaching.
Data Storage / Cloud Infrastructure
- Cloud Data Lake: Raw video + skeletal data stored (AWS S3, GCP Storage).
- Structured Database: Athlete profiles, performance logs, comparisons.
- Model Hosting: ML models deployed via APIs (AWS SageMaker, Vertex AI, Azure ML).
- Access Layer: Secure coach/athlete logins, dashboards, reports.
Real-Time Decision Support
For live applications (game, practice):
- Stream camera input → edge device computes → sends compressed skeletal vectors (not full video) to cloud → cloud ML model returns instant feedback.
- Latency goal: <200ms for AR/VR “coaching overlays.”
Commercial Applications
Where you can spin AI Agents into business:
- Athlete Development Platforms: subscription for players, parents, coaches.
- Team Integration: integrate with pro/college training rooms.
- Sports Medicine: injury prevention (detecting stress-inducing mechanics).
- Fan Engagement: AR apps showing “throw breakdowns” for entertainment.
Summary:
Many of the required AI Agents of today require an AI biomechanics lab with the following capabilities:
- Capture hardware (cameras, optional mocap).
- Edge + cloud compute stack.
- Pose estimation + biomechanics AI.
- Real-time coaching agent that delivers feedback.
- UI/UX for athletes and coaches.
Constructing AI Agent types requires a trick in balancing accuracy vs cost vs usability. A pro-grade mocap lab gives precise data, but costs hundreds of thousands. Using AI + commodity visual devices gives 80% of the value at 20% of the cost — perfect for a scalable commercial product. Design and layout is key.
