Hands-on practice in your browser
Draw an ontology, set a metrology budget, check which analyses your data supports, and train a robot. No sign-up needed.

Ontology · Knowledge graphIntermediate
Graph Schema Designer
Draw nodes and relationships on a canvas and get Cypher you can run in Neo4j. A manufacturing ontology preset lets you start from more than a blank screen.
- Manufacturing preset linking equipment, parts, faults, causes and actions
- Export Cypher as CREATE or MERGE
- Your drawing stays in the browser and can be saved as JSON
Design only. It does not grade or judge whether a schema is good.
ManufacturingIntermediate
Virtual metrology
When a process cannot be measured in full, measure a sample and estimate the rest from sensor values. Adjust the trade-off between metrology budget and escaped defects yourself.
- Change the sampling ratio, decision margin and process drift and the estimate is recalculated at once
- Compare missed defects and total cost against measuring everything
- See how the model ages over time, period by period
Process and measurement values are synthetic, not from real equipment.
Data analysisIntermediate
Data analyzer
Upload a spreadsheet and it judges what each column holds, then lists the analyses this data does and does not support, with reasons. It does not run the analysis for you; it tells you whether you should.
- Drop an .xlsx or CSV file to get a type judgement for every column
- No file? Start with example data that has a trap built in
- Files never leave your browser; all calculation happens there
Examples are synthetic. Do not carry their conclusions to the field.
Physical AIAdvanced
Balance robot lab
See why a robot trained in simulation falls over on real hardware. Choose which real component flaws (slow response, gear backlash, battery sag) to put into the virtual robot, and the browser trains a controller and runs it on 20 physical robots.
- Compare the score on the virtual robot with the score on physical robots
- Remove flaws one at a time and retrain to measure what made the difference
- Training runs in your browser, not on a server
The physical robots here are themselves a simulation built from component datasheet ranges.
Simulators open on AX Academy, the practice site of FDE Academy. These four work without signing up. Screens are in Korean.
