“I have spent my whole professional life developing robots and my companies have built more of them than anyone else”

Rodney Brooks, blog author 1 January 2024 Predictions Scorecard, 2024 January 01 (rodneybrooks.com)

Factual Their own work or organisation

Brooks has spent his whole professional life developing robots, and his companies have built more robots than anyone else's.

Mostly true True in substance, wrong in a detail.

Factual: Statements about the present or the past, checked against the record: did they hold up?

The second judge would not resolve this claim; the verdict shown is the first judge's.

What would count as true or false

There are two parts. The first is that Brooks's professional life has been devoted to robotics. The second is that companies he co-founded (iRobot, Rethink Robotics, Robust.AI) have together built more robots than any other company's. True if Brooks's career has centred on robotics and iRobot's cumulative units (e.g. over 40 million Roombas and other robots) exceed those of any other robot maker by reasonable measures, including industrial robot makers like FANUC. Mostly true if both hold broadly but with a caveat, such as non-robot academic roles or a disputed comparison with one rival. Mixed if one part holds and the other does not. Mostly false if another company (for example Ecovacs or another consumer robot maker) clearly built more robots, while the career part holds. False if both parts are wrong.

    “iRobot robot units shipped:2.463M units (FY 2024) vs 3.034M units (FY 2023). (Company-reported results)”

Reasoning

The IEEE biography describes Brooks as a robotics visionary who founded iRobot, Rethink Robotics and Robust AI (E2, E3). That supports the career part. Fast Company reports that iRobot has sold more than 50 million Roomba units (E5). FANUC, an industrial robot maker, reported 1 million cumulative robots shipped by August 2023 (E1), far fewer than the more than 50 million Roomba units reported for iRobot (E5). The caveat is that Roborock now holds a larger share of the robot-vacuum market than iRobot (22.3% against 13.7%, E6). No cumulative unit figures were given for Roborock or Ecovacs, so the comparison with consumer rivals is not fully settled.
