Product Requirements Document (PRD) Project: Automated Basketball Training System

  1. Product Vision (The Overarching Goal) To create the ultimate solo basketball training platform, enabling players to get consistent, high-repetition, and game-like practice without needing a human rebounder or passer, enhanced by real-time AI-driven feedback and performance analytics.
  2. Target Audience Serious individual players (High School, College, Amateur) Basketball coaches and training facilities Parents of aspiring players
  3. High-Level Architecture The system is composed of three primary, communicating components: Component A: “The Collector” - An autonomous mobile robot for ball retrieval. Component B: “The Tower” - A stationary passing, ball storage, and AI analysis unit. Component C: “The Hub” (Mobile App) - The central control and analytics application.
  4. Core Components & Functional Requirements Component A: The Collector Robot FR-A1 (Navigation): The robot must autonomously navigate on the surface of a standard basketball court. FR-A2 (Ball Detection): The robot must use sensors (e.g., a camera) to locate and identify a standard basketball. FR-A3 (Retrieval): The robot must be able to move towards a detected ball and guide it into a collection mechanism. FR-A4 (Homing): After collecting a ball, the robot must be able to navigate back to “The Tower”. FR-A5 (Depositing): The robot must have a mechanism to transfer the collected ball into the loading bay of “The Tower”. Component B: The Shooting Tower FR-B1 (Positioning): The tower is designed to be stationary and placed on or near the baseline of the court. FR-B2 (Ball Storage & Loading): The tower must contain a magazine to store multiple balls and a loading bay to receive balls from “The Collector”. FR-B3 (Player Tracking): The tower will use a computer vision system to identify and track the player’s position on the court with a field of view of at least 270 degrees. FR-B4 (Dynamic Passing): The passing mechanism must be able to launch a basketball towards the tracked player, varying the speed and trajectory to execute both chest passes and bounce passes. FR-B5 (Pre-Pass Indication): The tower must provide a clear visual and/or audible cue (e.g., a light flash, a specific sound) 1-2 seconds before a ball is passed. FR-B6 (Laser Guidance): The tower will be equipped with a low-power laser to project a dot onto the court, indicating the exact target location for the upcoming pass. This helps the player prepare for movement. Component C: “The Hub” (Mobile Application) FR-C1 (System Control): The app will serve as the primary interface to control the entire system—starting/stopping drills, selecting pass types, and manually operating the robots. FR-C2 (Shot Tracking): The app will interface with the Tower’s vision system to log shot attempts, makes, and misses from various locations on the court. FR-C3 (Performance Analytics): The app must process shot data to provide the player with detailed analytics, including shooting percentages from different zones. FR-C4 (Heat Map Generation): The app will generate a visual heat map of the court, showing the player’s shooting strengths and weaknesses. FR-C5 (Training Plans): The app will include pre-designed training plans and allow users to create and save their own custom drills.
  5. Advanced Integrations INT-1 (AI Coaching System): The system will integrate a real-time AI coach. Basis: The model will be based on the concepts from Google’s Gemini-powered AI Basketball Coach project. Functionality: Using the Tower’s camera feed, the AI will analyze the player’s shooting form (e.g., elbow alignment, release point, follow-through) and provide immediate, actionable feedback via a connected audio device (e.g., wireless earbuds).
  6. Non-Functional Requirements (How the system should BE) NFR-1 (Performance): Passes must be delivered to a 1-foot radius of the laser-indicated target. NFR-2 (Power): “The Collector” must have a battery life of at least 2 hours. “The Tower” will be AC powered. NFR-3 (Safety): Must include an emergency stop. The laser must be Class II or lower to ensure eye safety. NFR-4 (Usability): System setup should take less than 10 minutes for a single person.
  7. Future Enhancements / Product Roadmap Voice Commands: Allow for hands-free control of the system using spoken commands (e.g., “Hey Hoops, bounce pass, right elbow”). Multi-Ball Drills: Program rapid-fire passing sequences to different spots for more dynamic training. Gamification: Add challenges, leaderboards, and achievements within the mobile app to increase engagement.
