## Executive read

### BLUF

April is the year’s first official consumer-robot safety file: CPSC Release **08-256**, 25 April. Kyodo America recalls LawnBott robotic mowers LB2000, LB2100, LB3000, and LB3200 for laceration — blades that keep spinning when the machine is lifted, and side spacing that can let a foot past the shield. About **530** units. One minor-laceration report. Consumer Reports’ 7 April lawn-gear note had already judged the LB3200 Evolution “Not Acceptable” and asked CPSC to look. No RAPEX weekly-report twin was located. No Roomba recall.

### Key judgments

1. **[Assessment — High confidence]** 08-256 is a robotic-mower file, not a walk-behind. Official wording is lift-without-blade-stop plus foot-access past the side shield. Remedy is stop-use and register for repairs “ready by the end of June.”
2. **[Assessment — High confidence]** Injury count is the firm’s **one** report of minor lacerations on lift. Unit count is CPSC’s **about 530**. No death is stated. No child is named. None are invented.
3. **[Assessment — High confidence]** Friendly Robotics RoboMower RL1000, tested in the same CR note, is **not** recalled. CR’s comparison (blades stopped in about one second) is context, not a Robomow action.

### Analytic labels
- **Fact** — verified reporting or primary record
- **Assessment** — analytic judgment
- **Inference** — reasoned but not directly observed
- **Uncertainty** — unresolved information gap

### Source grades
- **A1** — authoritative primary record / directly confirmed
- **B1–B2** — generally reliable and corroborated
- **C3** — useful but requires caution (typical for forums)

## 01. CPSC 08-256 — Kyodo America LawnBott LB2000 / LB2100 / LB3000 / LB3200 (laceration; blade keeps spinning on lift)

*Event / publication dates: Consumer Reports media note 7 April 2008 (May 2008 issue); CPSC Release #08-256, 25 April 2008; Gizmodo reprint 26 April 2008*

**Product class.** Robotic lawn mowers

**Verified record — [Fact — A1 / B1]** On 25 April 2008 CPSC, in cooperation with Kyodo America Industries Co. LTD. of Lawrenceville, Ga., announced a voluntary recall of LawnBott lawn mowers. Official product name: LawnBott Lawn Mowers. **Units: About 530.** Manufacturer: **Zucchetti Centro Sistemi S.p.A., of Italy.** Hazard (official wording): “The cutting blades continue to rotate when the mower is lifted from the ground and the spacing on the side of the lawn mower could allow room for a consumer’s foot to go beyond the shield and be struck by the blade. Both instances pose a serious laceration hazard to consumers.” Incidents/Injuries (official wording): “Kyodo America has received one report of a consumer lifting the mower from the ground and suffered minor lacerations from the moving blade.” Models: **LB2000, LB2100, LB3000, and LB3200.** Description: “The robotic lawn mowers freely and automatically cut grass by detecting the signal of a perimeter cable. The mowers have a docking station for recharging and a shiny plastic cover sold in red, green or blue. ‘Evolution’ or ‘deluxe’ is printed on the side of the mower.” Sold by Kyodo America dealers nationwide from January 2006 through December 2007 for between $1,750 and $2,750. Manufactured in Italy. Remedy: stop using immediately and contact Kyodo America to register for repairs that will be ready by the end of June; registered owners “have been sent direct notification by mail.” [CPSC 08-256](https://www.cpsc.gov/Recalls/2008/cpsc-kyodo-america-recall-lawnbott-lawn-mowers-due-to-laceration-hazard); [Justia reprint of the official release](https://recalls.justia.com/household-and-office/lawn-mowers-and-accessories/08-256/); [Gizmodo, 26 April 2008](https://gizmodo.com/robot-lawn-mower-can-lacerate-probably-eat-humans-384355).

On 7 April, before the Commission page, Consumer Reports’ lawn-gear note (May 2008 issue) judged the LawnBott **LB3200 Evolution** “Not Acceptable.” CR tested it against Friendly Robotics’ $2,000 **RoboMower RL1000**. Official CR wording: when testers lifted the 78-pound RoboMower while mowing, “its blades stopped roughly 1 second after its wheels left the ground.” The 25-pound LawnBott’s “blade kept spinning until it was lifted beyond roughly 45 degrees. Even after that, its blade took nearly 4 seconds to stop. Either situation could harm an adult or a curious child.” CR “contacted the Consumer Product Safety Commission (CPSC) and asked it to investigate the LawnBott LB3200.” The U.S. distributor “said that a downloadable software update stops the blade within 1 second after the mower is lifted beyond about 35 degrees.” CR still judged the updated machine a serious safety risk. [Consumer Reports, 7 April 2008](https://www.consumerreports.org/media-room/press-releases/2008/04/consumer-reports-unveils-the-best-lawn-gear/).

No RAPEX weekly-report number for this SKU was located in April. No Health Canada RA number was opened this month. No CPSC Roomba or Scooba page.

**Threat landscape.** An unsupervised yard robot whose cutting means keep running after a lift, plus a side gap that can admit a foot. The physical harm named is laceration. One adult lift injury is stated; no pediatric case and no fatality are stated. The control named is a voluntary recall and a forthcoming repair, not a published particular-requirements standard.

**Forum / community notes.**
- none found.

**Intelligence assessment.** [Assessment — High confidence] Alert number 08-256, the four model numbers, about 530 units, Zucchetti / Kyodo America, Italy origin, the lift-and-side-shield hazard wording, and the one minor-laceration report are as the official release writes them. [Assessment — High confidence] CR’s 7 April stop-time measurements and “Not Acceptable” line are as the opened CR note writes them; they are a named-lab primary, not a regulator count. [Inference — Moderate confidence] A software patch that still needs a ~35-degree lift before the blade stops is a lift-sensor / disable-device gap, not a finished foot-probe control. [Uncertainty] Whether any RAPEX member-state file exists behind a weekly report that was not opened, and whether the June repair is a software load or a hardware shield, are unpublished in the 25 April copy. [Uncertainty] Canadian inventory is not stated on the CPSC page.

**Opportunity.** A dated Health Canada or RAPEX twin, a repair-completion notice, and a particular-requirements standard for robotic battery mowers (none published this month).

**LRRK relevance.** Sense / Move / Act: blade-stop-on-lift and side-shield / foot access. Watch: CPSC 08-256. Lab: lift/tilt blade-stop and line-of-travel / side-gap probe.

**Confidence.** High on the 25 April official text, the 530-unit figure, and the one stated injury. High on CR’s 7 April “Not Acceptable” and the stop-time comparison as written. Moderate on the June repair actually landing as a one-second stop. Low on unpublished EU or Canadian numerators. B1 on named-newsroom reprints of the Commission release.

## Forward indicators

1. Any Health Canada or RAPEX twin of 08-256 / Zucchetti LawnBott, with an official ID.
2. Kyodo America’s end-of-June repair notice, and whether it is software, shield, or both.
3. Any official iRobot Roomba or Scooba recall.
4. Any other robotic-mower lift-sensor or blade-access file (Automower, Robomow, private label).
5. Any brand-named robotic-mower pediatric case.

> **Collection integrity.** One signal graduated (CR 7 April + CPSC 08-256, same SKU/hazard). **Excluded:** Friendly Robotics RoboMower RL1000 (CR comparison only; not recalled); walk-behind and ride-on pages in the same CR lawn issue (out of class). No CPSC Roomba or Scooba page. No RAPEX robotic-mower weekly report located this month. No named robotic-mower fatality. Forum empty.
