# M4 video: Pick and place

> For agents: start with the [agent guide](https://parol6.build/llms.txt). Every page is Markdown by default; add `Accept: text/html` for HTML.

**Status: planned.**

This page links Joel's video for [M4. Pick and place](/lore/m4-pick-and-place) once it is published.

## Plan

**Working title:** My robot can pick things up now (and how repeatable is 0.1 mm really?)

Beats:

1. Choosing the gripper.
2. The TCP explainer.
3. The first program.
4. A 20-cycle timelapse.
5. The measurement.
6. The result.

**Teaches:** Frames, programming, and accuracy against repeatability.

## Terms

- **M4 video**: the published video for milestone 4.

## Lore on this page
