ENGN8170 · PROJECT ONE

We are ENGN8170 Group 01.

Reproducing and verifying EntoSieve.

EntoSieve sorts insect bulk samples by maximum body dimension. Our first goal is to build and test a usable, reproducible baseline with client-prepared samples. Only after that will we evaluate agreed improvements.

02 · THE PROJECT

What we are working on

Our current working scope protects a reproducible EntoSieve baseline first, then allows agreed improvements to be evaluated against recorded evidence.

01 · The challenge

Reproduce and verify EntoSieve

The confirmed baseline sorts by maximum body dimension into three groups: 3 mm or below, greater than 3 but less than 10 mm, and 10 mm or above. Exactly 3 mm belongs to the lower group; exactly 10 mm belongs to the upper group.

02 · The stakeholders

Clients, operators and specimens

Dr Megan Head and Josh are recorded as the clients and primary stakeholders. The team will work with client-prepared samples, consult the clients on material decisions and treat specimen integrity and laboratory handling as important operating constraints.

03 · The baseline outcome

A usable, reproducible system

The protected first priority is to build, operate and test a traceable baseline, then organise the configuration and guidance needed to reproduce another unit. Agreed improvements follow the baseline; marine-invertebrate application remains conditional stretch work.

This summary reflects current controlled review records. Classification performance, repeatability, specimen-damage criteria and the formal approval route remain pending.

03 · WHY IT MATTERS

Evidence before assertion.

The value of this project will be demonstrated through sourced evidence, measurable requirements and transparent verification—not through unsupported promotional claims.

SRC Source every factREQ Trace every decisionTST Verify every pass

04 · OUR APPROACH

How the project moves forward

Three clear phases show what we are doing now, what comes next and what evidence will be needed before the project is complete.

  1. Stages 01–02Baseline set

    Understand & Define

    The client problem, system boundary and confirmed size and exposure constraints are recorded. Quantitative verification criteria remain open.

  2. Stages 03–04Supporting

    Explore & Design

    Controlled source and configuration records support reproduction. Remaining interfaces and as-built deviations will be closed through assembly.

  3. Stages 05–06Current

    Build & Verify

    The main frame is in assembly. Fit observations are informing controlled part adjustments while alignment, wiring, commissioning and staged verification remain ahead.

05 · PROGRESS LOG

What we have done so far

This log records project decisions and engineering work—not changes to the website. Items are presented from earliest to latest, with each update stating what is supported and what still needs confirmation.

Physical baseline taking shape

The main frame, vertical drive components and several printed interfaces have been assembled. This is physical build evidence, not yet evidence of alignment, complete wiring or successful operation.

A close view of the lead screw, coupling and linear stage records their current physical relationship. Alignment and motion checks are still required.

Client constraints

Operating boundaries clarified with the clients

Confirmed

The client meeting record confirms the maximum-body-dimension sorting rule, the three size groups, RN Robertson laboratory controls and client stop authority. Quantitative sorting-performance and specimen-damage acceptance criteria remain pending.

Audit response

Audit 1 feedback converted into an action plan

Working record

Audit findings, follow-up actions, affected artefacts and source links have been consolidated into a control register. The current priority is to close the gap between strong planning and demonstrated build-and-test evidence before Audit 2.

Verification planning

A staged test path is being prepared

Working plan

The test path now runs from dry mechanical and electrical checks through motion integration, wet checks and end-to-end trials. Results remain Not Started until dated evidence is captured.

Document control

Controlled project files have moved forward

Controlled review

ConOps v1.5 corrects the lower group to d ≤ 3 mm and supersedes earlier lower-bound wording. PMP v0.5 remains the current Audit 1 review snapshot, while Test Plan v1.0 is a working plan. These labels do not imply formal approval or completed testing.

Physical baseline

Hardware preparation is nearing completion

Build in progress

Physical hardware is largely prepared, and the team reports that most 3D-printed parts are complete. Receipt checks, fit and quality checks, assembly and as-built recording remain in progress.

Physical integration

The baseline frame has moved into assembly

Assembly in progress

The aluminium-extrusion frame, linear stage, lead screw, motor and printed mounting interfaces have been brought together in the current assembly. The photographs record physical progress; final alignment, wiring, full-motion, load and safety checks remain open.

Design iteration

Assembly feedback has driven a part adjustment

Prepared for fabrication

Fit observations from assembly were used to adjust a paired mounting or support component. The revised geometry has been prepared in the slicer; printing, installation and verification are still pending.
