Before 2018 Rodney Brooks had worked on humanoid robots for over twenty-five years and built research humanoids and thousands of humanoid robots deployed in factories.

True if records show that by January 2018 Brooks had worked on humanoid robots for more than 25 years (e.g. Cog at MIT from the early 1990s or earlier), had built research humanoids, and had built thousands of humanoid robots deployed in factories (e.g. Rethink Robotics' Baxter and Sawyer units, if these are humanoid as the claim treats them). Mostly true if all three parts hold but the span is slightly under 25 years or the number deployed is somewhat below 'thousands'. Mixed if only one or two of the three parts hold. Mostly false if the factory robots are clearly not humanoid, or only a handful were deployed, while the research humanoid work is real. False if he did not build research humanoids or factory-deployed humanoid robots in those periods.

Set before the research began.

   “It is unclear exactly how many robots Rethink sold, but The Robot Report in September 2015 reported the company “recently passed the 1,000 sales mark.””

2. E2 Rethink Robotics – RobotEnomics RobotEnomics (WordPress blog) · 16 January 2017

   “Since the company began shipping Baxter in 2012 a cumulative number of between 850 and 900 Baxter robots have been installed worldwide.”

3. E3 MIT Cog Springer (Humanoid Robotics: A Reference) · 10 October 2018

   “Starting in the summer of 1993, Cog was one of the first humanoid projects in the United States and was a departure from many of the traditional methods promoted by artificial intelligence research at the time.”

4. E4 Groundbreaking maker of gentle factory robots shuts down Ars Technica · 8 October 2018

   “Back in 2014, we wrote about Baxter, an anthropomorphic factory robot that was gentle enough to work alongside human workers.”

The evidence shows that the Cog humanoid project started in summer 1993 [E3], that Baxter was an anthropomorphic factory robot [E4], and that roughly 850 to 1,000 Rethink or Baxter robots were sold or installed [E1][E2]. None of the quoted evidence names Brooks or links him to Cog, Rethink or Baxter, so it cannot show which parts of the claim hold for him.
