[Virtual Robot Race] AI Driving with CNN & MLP: End-to-End Imitation Learning [Beta 1.3]

*[Virtual Robot Race] AI System Architecture Deep Dive*

Can an AI learn to drive just by watching a human? 🧠🏎️
In this episode, we explore the *End-to-End Imitation Learning* system that powers the Virtual Robot Race Beta 1.3. We're moving beyond explicit coding into the world of Neural Networks and PyTorch.

We break down the entire "Brain" of the robot, from raw pixels to driving commands. This is a perfect case study for students interested in how Convolutional Neural Networks (CNN) and Multi-Layer Perceptrons (MLP) work in a real-time robotics environment.

*👇 Technical Deep Dive:*

*End-to-End Learning:* The system learns to map camera images directly to driving commands (Steering & Throttle) by imitating expert demonstrations.
*The Architecture (CNN + MLP):*
*CNN Feature Extractor:* A 4-block convolutional network that compresses a 224x224 RGB image into 256 essential visual features.
*MLP Head:* A series of fully connected layers that combine visual features with the *SOC (State of Charge)* to make final driving decisions.


*Battery-Aware Driving:* By concatenating SOC data, the network can learn to adjust its strategy based on remaining battery life.
*Training with DAgger:* Discover how we use *Dataset Aggregation (DAgger)* to help the AI recover from mistakes it hasn't seen in the initial training data.
*Optimization:* Details on Weight Initialization (Kaiming Normal), Dropout for regularization, and the MSE loss function.

*🚀 Train Your Own AI:*

1. Collect driving data by racing manually in the simulator.
2. Run the `train.py` script to teach your model.
3. Use the DAgger pipeline to iteratively improve your AI's lap time.
