CloudLabs Building a Catapult vs Experimentor

In this simulation, you are tasked with repairing a wooden catapult, as some of its parts have broken. To do this, you must take its measurements and configure the rapid prototyping machine that prints the parts to be replaced. Once you have repaired the broken parts, you must verify if the catapult works correctly.

Experimentor turns your iPhone into a powerful science data collection tool. With 16 built-in sensors, live charts, a customizable dashboard, web streaming, and AI-powered vision — it's the easiest way to run real experiments and learn about the world around you. COLLECT DATA FROM 16 SENSORS • Motion: Accelerometer, Gyroscope, Magnetometer, Gravity, Linear Acceleration, Rotation • Environment: Barometer (altitude & pressure), Location (GPS coordinates, speed, altitude), Sound Level (microphone), Light Level (camera) • Device: Battery, Screen Brightness, Proximity • Connectivity: Wi-Fi & Cellular signal strength • AI Vision: Object Detection and People Counter (powered by YOLO) REAL-TIME VISUALIZATION • Watch live charts update as you collect data • See min, max, average, and latest readings for every variable • Switch between sensors with a tap • Mark important moments during recording with markers STREAM TO ANY BROWSER • Turn on the built-in web server and open the URL on any Chromebook, laptop, or tablet • Scan the QR code or type the URL into Chrome — no app install needed • Live dashboard with sensor cards, sparkline charts, and a data table • Uses Server-Sent Events — works on any modern browser over your local Wi-Fi CUSTOMIZABLE DASHBOARD • Build your own live dashboard with 4 widget types: Gauge, Number, Bar, and Sparkline • Pick any sensor variable for each widget • Stream real-time data to all widgets at once • Rearrange and customize your layout FLEXIBLE UNITS • Tap any unit label to instantly convert (G-force ↔ m/s², radians ↔ degrees, kPa ↔ atm, and more) • 30+ unit conversions across acceleration, angles, distance, speed, pressure, temperature, and altitude EXPERIMENT TEMPLATES • 12 ready-to-go experiment templates for quick setup • Covers physics, environmental science, and everyday curiosity • Great for homework, science fairs, and classroom demos EXPORT YOUR DATA • Export to CSV for spreadsheets or JSON for code • Share results with classmates and teachers • All data is collected and stored on your device — nothing is ever uploaded CONTEXTUAL HELP EVERYWHERE • Every screen has a (?) info button explaining all buttons and features • Built-in walkthrough tour and complete help guide • Kid-friendly language and step-by-step instructions • No account required, no ads, no tracking Whether you're measuring the acceleration of a roller coaster, mapping sound levels around your school, streaming live data to a Chromebook, counting objects with AI, or tracking air pressure during a storm — Experimentor makes it easy, fun, and educational.
