Project Description & Goals:
Build and train miniature autonomous cars to drive in a miniature city.
RASCAL (Robotic Autonomous Scale Car for Adaptive Learning): Using the car sensors, offload image and control data onto a server node. This node will use a neural network that will train the vehicle to move around on its own given the image data it sees through its camera.

​GitLab

Technologies: ROS (Robot Operating System), Pytorch

Week 1:

​Week 1 Slides

Progress:

• Familiarize with past summer's work:​GitLab, RASCAL setup, ​Software Architecture
• Debug issue with RASCAL's pure pursuit

---

Week 2:

​Week 2 Slides

Progress:

• Setup X11 forwarding for GUI applications through SSH
• Visual odometry using Realsense Camera and ​rtabmap
• Streamline data pipeline that processes bag data (car camera + control data) into .mp4 video
• Detect ARUCO markers from a given image using Python & OpenCV libraries
• Setup Intersection server (node with GPU)
• Develop PyTorch MNIST model
• Trained "yellow thing" neural network
• Line up perspective drawing with camera to determine FOV

---

Week 3:

​Week 3 Slides

Progress:

• Created web display assassin to eliminate web server when closing ROS
• Tested "yellow thing" model, great results
• SSHFS setup
• Calibrate Realsense camera
• Created "snap picture" button on web display for convenience
• Developed python script to detect ARUCO marker and estimate camera position
• Tested point cloud mapping with rtabmap
• Attempt sensor fusion with encoder odometry and visual odometry
• Data augmentation to artificially generate new camera perspectives from existing images

---

Week 4:

​Week 4 Slides

Progress:

• Refined aruco marker detection for more accurate car pose estimation
• Trained model with video instead of images
• Improved data pipeline from car sensors to server
• Refined data augmentation to simulate new camera perspectives
• Added more data visualization (Replayer) to display steering curve, path, and images to web server

Week 5:

​Week 5 Slides

Progress:

• Aruco Marker Detection now updates car position within XY plane. Finished self-calibration system
