The problem

The Manual Process Consisted Of Two Issues
Time & Truth

Before — stopwatch, clipboard, and multiple open tabs

  • Video scrubbed by hand after the run, timestamps read off playback and written down before the next state change passes.
  • Stopwatch runs separately from the footage, leading to two time sources that never fully agree.
  • Substates named differently depending on who ran the study, cycle boundaries drawn inconsistently.
  • Raw times transcribed into Excel by hand, durations calculated manually.
  • Balance chart built column by column in a separate file before anything can be presented.
  • Multiple hours per station, most of it administration rather than analysis.

After — one workspace, one export

  • Engineer loads footage, registers robots, and runs through the video once. The user selects the robot, category, and clicks start/stop while watching the video to gather accurate durations.
  • Every event is stamped against the video timeline, resolving to a tenth of a second.
  • Structured category and substate buttons replace handwriting — naming is consistent across every study.
  • Yamazumi chart, event log, and export are generated automatically when the last robot is finalized.
  • No manual math, no chart to build, no files to reconcile.
  • Users can upload files back into the software to resume working, update, edit, and delete any information that is needed.
  • Across controlled tests on a single operation, completion time dropped by roughly 47%. The reduction came from eliminating every step that was not the actual observation.
How it works

Entire Workflow In One Workspace

Platform workspace: video panel with a color-coded event timeline, cycle time header, and the robot registry listing weld and transfer robots with VA, NVAN, NVA, and NVAI totals
The full workspace: study header on top, video and its color-coded event timeline on the left, and the robot registry on the right with per-robot lean totals. (Robot footage is intentionally obscured here to maintain privacy of manufacturer)
01

Frame-Level Video Control

Zoom up to 8x, pan across the cell, annotate and draw directly on the frame, and slow down or speed up playback to 3x to catch state changes to the video frame.

02

Multi-Robot Registry

Weld, transfer, vision, bracket, combo robots, etc. All robots are registered per station, each tracked independently with their own event stream and running totals.

03

Four Lean States, Real Substates

Every logged event is classified as VA, NVAN, NVA, or NVAI with a specific substate such as welding, positioning, tool change, blocked, or dimensional check. Buttons are fully customizable, add or remove substates per category so the taxonomy matches the cell.

04

Home-Position Cycle Detection

Left Home and At Home markers set cycle boundaries automatically, so cycle time is derived from the study itself rather than entered by hand.

05

Study Intelligence

Waste report, cycle analysis, and takt status run on demand against the logged data. No export round trip required.

06

One-Click Reporting

Excel, PowerPoint, and PDF export with summaries, robot analysis, event log, and generated yamazumi data. Users can save and reload prior studies for side-by-side comparisons.

Live data

Time Study, Visuals, Data, Event Log On One Screen.

Nothing is entered twice. As the footage plays, the event log, the per-robot totals, and the balance chart update naturally so the engineer running the study is reading results, rather than transcribing them.

Study workspace at 8x zoom: takt set to 70 seconds, live balance chart with eight robot columns, and the event log listing waiting, assembly, loading/unloading, and positioning events for BR2 with start and end times
Target Takt entered once in the header; the balance chart and utilization percentages recompute against it live. The event log on the right is the source of truth.
Quick stopwatch panel beside the zoomed video: robot WR1 selected, timer reading 00:14.1, with GO, STOP, reset, and save time controls
Quick stopwatch mode for spot checks, cycle times and validation runs.
Edit study details dialog: study notes field above an editable table of events with category, substate, robot, operation number, notes, parts welded, weld location, and quality columns
Every row stays editable after initial export. Operation number, parts welded, weld location, quality flag, and free-form notes. Process context lives next to the timing instead of in a separate spreadsheet.

Single clock

Timing is stamped against the video timeline, so any figure can be replayed and re-checked frame by frame.

Editable, not rigid

Categories, substates, and row detail are all editable, so the taxonomy matches the cell rather than the tool.

Traceable by row

Every second in the chart resolves to a numbered event with a start, an end, and a robot attached to it.

Yamazumi output

From Logged Events To a Professional Visual

The software automatically generates a complete Yamazumi chart as a byproduct of logging. There is no second step, no manual chart build, no Excel formatting. The output is ready to present upon export.

Exported yamazumi chart with eight robot columns totalling about 71.5 seconds each against a red takt line at 70 seconds

Exported balance chart: eight robot columns against the red takt line at 70 seconds, with utilization printed under each column.

Robot analysis

Each Robot Gets Its Own Detailed Analysis

Exported robot analysis sheet for VR1 listing numbered events with category, substate, start time, end time, and duration, followed by total VA, NVAN, NVA, and NVAI time
Exported robot analysis: every event for that robot with category, substate, start, end, and formatted duration, then rolled up into total VA, NVAN, NVA, and NVAI time. Titled "Robot Analysis" on generated Excel export.
State logger

Video Player Complete with Zoom and Video Speed Playback

Platform zoomed to 5.8x on a welding robot with the state logger panel open, showing Left Home and At Home markers and substate buttons grouped under VA, NVAN, NVA, and NVAI
Zoomed to 5.8x and dragged onto a single robot, with the state logger open beside it. Seventeen substates across four lean categories. Every event is specific enough to drive a corrective action.

Impact

47%

Faster than the manual baseline end to end, including report formatting.

±0.1s

Event timing resolution, stamped against the video clock not a stopwatch.

100%

Every figure traceable to a source event in the timestamped log.

Validated by running built-in stopwatch mode in parallel with video-synced logging on the same footage and cross-checking against studies completed by hand.

Architecture

Client-Side By Design. No Data Is Saved, No Data Is Shared

A fully client-side single-page application. Video is read locally in the browser and never uploaded, which keeps recorded footage on the machine it was captured on, and means a study runs on a laptop with no network at all.
