The four tiers
A tier is authored teaching, not a filter. Each tier asks something different of the same machine. Every tier stays open to everyone: choosing one only decides which panel opens first on each section. These definitions are the project's own, word for word.
Beginner
- For
- Anyone with no robotics background: a visitor, a new operator, a manager
- Question it answers
- What is this machine, what is it for, and how do I stay safe?
- Leaves able to
- Say what S2 does, where it sits in the flow, what goes in and comes out, and what can hurt them (spec §2)
- Kind of task
- Recognise and recall, with plain-language explanations and pictures
- Confidence classes
- Shown on every claim; Beginner learns what Verified, Inferred and Assumed mean
- Typical corpus use
- Overview and role claims; beginner safety claims; the S2 cycle
Novice
- For
- Someone who will work near or with the cell: operator, trainee technician
- Question it answers
- How does it work, and how is it run day to day?
- Leaves able to
- Explain the major components and the operating sequence; read a status light and an error; recognise which safety functions exist and which S2 safeguards are unconfirmed
- Kind of task
- Explain and sequence: put steps in order, match parts to their functions
- Confidence classes
- Used to separate manufacturer facts from S2 assumptions
- Typical corpus use
- Components, the operating sequence, safety functions
Intermediate
- For
- Someone who will set up, program or maintain the arm: technician, student engineer
- Question it answers
- How do I set it up, program it and recover it?
- Leaves able to
- Carry out the setup and operating sequence; choose a motion mode; clear an error; explain what the controller I/O and report ports carry
- Kind of task
- Apply: work through written scenarios that need a decision (which mode, which setting, what to do about this error), with feedback on each choice. Simulation added in M2/M4 extends this; it does not define it
- Confidence classes
- Used when choosing which source to trust
- Typical corpus use
- Interfaces, operation steps, error handling
Expert
- For
- Someone who designs, integrates or changes the cell: integrator, engineer, the M5 team
- Question it answers
- How do I choose interfaces, reason about cycle time, integrate it with the cell, and anticipate failures?
- Leaves able to
- Justify an interface choice for a task; identify cycle-time contributors; reason about the two-arm split and the S2 placement policy; analyse failure modes, including conflicting sources and unrated safety functions
- Kind of task
- Analyse and decide: weigh trade-offs, resolve contradictions, critique a configuration
- Confidence classes
- Reasoned with: the learner explains why a claim is Inferred, and what would verify an Assumed one
- Typical corpus use
- Specs with contradictions, gaps, the integration and levels records, recommendations
