UDHY Tools
Free engineering calculators for robotics and autonomous vehicle perception — built to answer the practical questions that come up when designing a sensor stack, not just explain the theory.

SENSOR PLANNING
LiDAR Point Cloud Density Calculator
Estimate points per square meter, point spacing, and detection reliability at any range — using your sensor’s real beam count and firing rate.
→
LOCALIZATIONGPS-Denied Dead-Reckoning Drift Estimator
Estimate how far position error grows during a GPS outage, based on IMU grade and speed — and how long you can navigate before drift exceeds GPS-level accuracy.
→
REAL-TIME PERFORMANCEPerception-to-Control Latency Budget Calculator
Break down your pipeline’s end-to-end latency — sensor to actuator — and see whether it fits your target control loop rate, plus distance traveled blind.
Each tool includes a plain-language explanation of the math and links to the relevant deep-dive articles on UDHY.com. More calculators are added as new topics come up in the course content.
