M-900iB/280
FANUCThe FANUC M-900iB/280 is a heavy-payload, 6-axis industrial robot with a 280 kg payload capacity and 2655 mm reach (or 3103 mm in the /280L long-arm variant), designed specifically for maximum structural rigidity and precision in demanding applications such as flow drill screwing, roller hemming, material removal, and heavy part handling. It features a completely redesigned J3 arm for stiffness, ISO 9283 rigidity compliance, IP67 wrist/J3 arm protection, and is controlled by the R-30iB Plus controller. As a fixed industrial robot arm, it performs its programmed tasks fully autonomously once deployed and programmed — no human performs or drives the task during operation. Research papers from KTH and Osaka University reference the M-900iB platform for imitation learning and bilateral control experiments, confirming its use in advanced autonomous manipulation research.

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].
