Preemptiv
đź§ Detecting Neurological Emergencies Before They Happen
Inspiration
Every 40 seconds, someone in the United States suffers a stroke, and hundreds of thousands die or are permanently disabled each year due to delayed detection and response.
Neurological events often begin silently in the brain, long before visible signs like slurred speech or weakness appear. In stroke care, every minute counts–faster intervention saves brain cells, reduces disability, and improves survival.
What if we could detect danger early and act instantly?
What it does
Preemptiv is a continuous, real-time neural monitoring and response system that detects early signs of neurological distress–before overt symptoms appear–and triggers assistive actions to buy critical time.
EEG Signal Acquisition & Processing
On-device signal processing filters noise and extracts features associated with early distress.
Anomaly Detection + Confidence Thresholding
When patterns match high-risk signatures, the system triggers a safe alert.
Robotic Arm Control
Once intent is confirmed, our system sends commands to a servo-driven robotic arm. Preemptiv’s robotic arm executes assistive tasks such as calling for help or offering objects to the patient–all without the need for caregiver intervention.
On-Device OpenCV Vision Pipeline (GPU/OpenCL-ready)
Real-time vision runs fully on-device to localize the user’s features and track parts of interest, enabling precise actions including the feeding motion while keeping latency low–Leveraging Dragonwing + OpenCL-capable GPU compute.
How we built it
Hardware:
Muse 2 EEG
Arduino Uno Q for servo control (provided by Qualcomm)
HiWonder servo robotic arm
Custom 3D printed camera mount for arm
Paper plate
Cheetos
Accomplishments that we're proud of
Built a fully functional brain-to-robot pipeline in under 36 hours
Successfully fed a team member Cheetos hands-free using only brain signals
Nobody got hit in the face by the robot arm
No fried Arduino boards
What we learned
Duct tape the arm to the table (and the plate)
Cheetos are orange
