Sense, decide, and move items
Connect inventory measurements to controlled transport and storage. 11 circuits, each one running in the simulator with a prediction to make before you run it.
The steps
- Container fullness
Turn inventory contents into a small numeric signal.
Concepts: Measurement, Quantization, Signal strength - Comparator threshold
Pass a signal only when it meets a reference.
Concepts: Comparison, Threshold, Boundary cases - Comparator subtract
Compute a nonnegative difference between signal strengths.
Concepts: Arithmetic, Saturation, Numeric signals - Container empty alarm
Turn an empty inventory into an explicit condition.
Concepts: Sensor boundary, Zero test, Inversion - Container full alarm
Detect a high inventory boundary.
Concepts: Threshold, Capacity, Boundary testing - Hopper line
Follow items through a directed transport path.
Concepts: Direction, Throughput, Pipeline - Hopper lock
Use a control signal to stop an item path.
Concepts: Enable, Flow control, Stored contents - Item sorter
Combine a content filter, a threshold, and controlled transfer.
Concepts: Filtering, Threshold, Invariants - Pulse-driven dropper transfer
Move one inventory item per accepted activation.
Concepts: Event-driven transfer, Direction, Receiver capacity - Automatic dropper feeder
Repeat a transfer while inventory still needs service.
Concepts: Feedback, Service loop, Empty detection - Fullness-controlled overflow storage
Give excess items a defined destination.
Concepts: Backlog, Capacity, Fallback routing
