Session by session

  1. Session 41 · Ask & understandWeek 21

    How do robot arms move?

    Evidence: a question, sketch or new vocabulary

  2. Session 42 · Build & designWeek 21

    Assemble the pre-cut arm parts

    Evidence: a design draft, dataset or build

  3. Session 43 · ImplementWeek 22

    Connect the syringes and add water

    Evidence: a working version, explained once

  4. Session 44 · Test & improveWeek 22

    Lift light objects and check for leaks

    Evidence: a test log with at least one failure

  5. Session 45 · Explain & reflectWeek 23

    Explain push and pull through the tube

    Evidence: an individual explanation

Materials & tools
  • Pre-cut cardboard parts
  • syringes
  • plastic tubing
  • coloured water
  • spill tray
Minimum test

Three light objects lifted; tubes checked for leaks over the tray.

Hands-on mechanism

A physical build that moves with no electricity at all.

Completion needs the artefact, an honest test log, an individual explanation and no open safety or privacy issue.

Robotics project

A physical circuit, sensor or mechanism, built and tested.
