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

Start here at Intermediate

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
