M-900iB/400L
FANUCThe FANUC M-900iB/400L is a large, floor-mounted 6-axis industrial robot arm manufactured by FANUC, featuring a 400 kg payload capacity, 3,704 mm reach, and ±0.1 mm repeatability (per official datasheet). It is controlled by the R-30iB Plus controller and is suited for heavy-duty applications including material handling, palletizing, press transfer, and heavy-duty spot welding. The robot is noted as out of production by at least one source, though it remains available on the secondary/used market. Several extracted facts relate to unrelated research papers (bimanual robots, mobile manipulation benchmarks) that appear to have been incorrectly associated with this system and are not reconciled as M-900iB/400L specifications. As a pre-programmed industrial robot arm, it executes its assigned tasks autonomously once deployed, with no human performing or driving the task during operation.

Evidence-graded claims from the FANUC deep report
FANUC industrial robots (welding, palletizing, painting, assembly, machine tending) operate fully autonomously once programmed — no human performs or drives the task during operation.
Independent community practitioners on Reddit (r/PLC, r/robotics) confirm FANUC robots run their assigned tasks independently in live production environments, consistent with the autonomy verdict (confidence 0.93); no evidence of remote human task-driving was found [16][19][20].
from FANUC deep report →FANUC's hardware is well-built, reliable, accurate, and very long-lived in real-world industrial deployments.
Independent community sources on Reddit (r/PLC) corroborate hardware reliability and longevity claims, explicitly contrasting strong hardware quality against software shortcomings [16][17][19].

FANUC is showcasing Physical AI and AI-enabled robotics, including a collaboration with Google AI for agent-powered robot operation, representing a meaningful leap in adaptive autonomy.
Evidence is limited to FANUC America's own press releases from Automate 2026 — no independent third-party testing, customer deployment data, or external validation of the AI capability claims has been identified [11][14].
from FANUC deep report →FANUC America announced a $90 million investment to construct an 840,000 sq ft robot manufacturing facility in the US (announced March 2026).
The investment announcement is confirmed by a PR Newswire press release and LinkedIn corroboration, but these are distribution channels for the company's own announcement — no independent journalist investigation, regulatory filing, or construction verification has been identified; the facility is not yet built [10][12].

FANUC robots achieve high positional accuracy in real-world deployments, consistent with advertised specifications.
Independent practitioner reports on Reddit (r/Fanuc, r/PLC) document ~0.3 mm positional error in real-world mid-range positions and express skepticism about trusting advertised performance data, indicating a gap between spec-sheet claims and field reality [18][19].
