YK400X
Yamaha RoboticsThe YK400X is a legacy 4-axis SCARA robot from Yamaha Motor's industrial robotics division, featuring a 400 mm arm reach, up to 4 kg payload, ±0.01 mm repeatability, and a standard cycle time of approximately 0.41–0.45 seconds. It was controlled by the RCX142 controller with MPB-125 teach pendant and has been superseded by the YK400XR and later YK-XE series. Sales were discontinued in December 2020 with service support running until December 2027. Several extracted facts (YubiKey pricing, XPG-RL research, X-Loco humanoid, XR teleoperation framework) are clearly unrelated to the YK400X and have been excluded from the reconciled picture. The robot autonomously executes programmed industrial tasks (assembly, part transfer, sealing, screw tightening) without human task performance, consistent with the Autonomous level.

Evidence-graded claims from the Yamaha Robotics deep report
Yamaha's industrial robots (SCARA, Cartesian, cobot, surface mounters) operate fully autonomously once programmed — humans only perform setup, commissioning, and maintenance, not the tasks themselves.
An independent industrial maintenance community on Reddit [13] confirms these robots operate in production environments with human involvement limited to commissioning and maintenance, corroborating the vendor's autonomy description — though the sample is anecdotal and not a formal audit.
from Yamaha Robotics deep report →Yamaha Motor acquired Robotics Plus to build autonomous AI-powered equipment for the specialty crop agriculture market.
Robotics Tomorrow [10], an independent trade publication, reported the acquisition with a direct quote from the announcement, confirming the deal and its agricultural autonomy focus — though actual deployed product performance in the field remains unverified.

Yamaha's 7-axis cobot autonomously adapts its posture to avoid interference in confined spaces, enabled by torque sensors in all 7 axes — without human intervention during task execution.
Only Yamaha's own official product page [2] describes the 7-axis structure and torque sensors; no independent test, customer report, or third-party benchmark in the dossier verifies the autonomous posture-adaptation claim in real-world deployment.
from Yamaha Robotics deep report →The cobot achieves ±0.04 mm repeatability (ISO 9283) with a 10 kg payload at 1,300 mm reach and 3,000 mm/s TCP speed.
All four specifications are sourced exclusively from Yamaha's own official product page [2]; no independent lab test, standards-body certification result, or third-party validation appears in the dossier.
from Yamaha Robotics deep report →Yamaha established the TY ROBOTICS joint venture with TOYO in August 2025 to transfer single-axis and Cartesian robot production and expand the model lineup.
The sole source is Yamaha Motor's own official news release [11]; no independent reporting, regulatory filing, or third-party confirmation of the joint venture's operational status or production transfer progress appears in the dossier.
from Yamaha Robotics deep report →Yamaha's SCARA robots offer up to 1,200 mm arm reach and 50 kg payload, while Cartesian/single-axis robots achieve ±5 µm repeatability with strokes up to 4,050 mm.
These specs come from a 2017 distributor catalog PDF [4] (YRG Inc.), which is not an independent test and is nearly a decade old; current model specifications may differ and no third-party benchmark validates these figures.
from Yamaha Robotics deep report →Yamaha's cobot is commercially deployed across multiple real-world process applications — screw tightening, sealing, visual inspection, polishing, and connector insertion — with named partner companies for each process.
Partner companies (SANYO MACHINE WORKS, ThreeBond, Phoxter, FUJI CORPORATION) are listed only on Yamaha's own product page [2]; no independent customer case study, production volume data, or third-party deployment report in the dossier confirms actual at-scale commercial deployment.
