What this site is
Robotics Engineering Lab is a small independent editorial site about 6-DOF robot arms. The useful part of the library is practical: Arduino and servo power, inverse kinematics, ROS 2 control, grippers, and how a robot cell talks to a PLC. The industrial brand pages exist so a buyer can read payload, reach and safety context in one place — they are not substitute datasheets and they are not lab reviews.
We publish in English for readers in the USA and Canada, because the safety citations we use most often are ANSI/RIA R15.06, CSA Z434 and ISO 10218.
What we cover
The tutorial library is grouped into eight topics:
- Arduino and embedded control — microcontroller wiring, servo buses, encoders and sensors.
- ROS 2, kinematics and software — ros2_control, inverse kinematics and simulation.
- Industrial automation and safety — PLC integration, e-stops, light curtains and North American standards.
- Mechanical design and materials — printed parts, aluminum links, belts, gears and cable routing.
- End effectors — jaws, vacuum and magnetic tools.
- Maintenance, calibration and vision — upkeep and sensing around a cell.
- Specification notes — buying notes compiled from manufacturer documentation.
- Business tools — including the ROI calculator and payload calculator.
How we label content
We do not pretend every page was run on a $30,000 industrial arm. Pages fall into three buckets, and the page itself should make the bucket obvious:
- Worked examples — Arduino sketches, wiring steps, kinematics math and the two browser calculators. These are meant to be reproduced.
- Engineering explainers — safety, materials, grippers, cooling, cabling. They cite standards or manufacturer practice. They are not a certified risk assessment.
- Specification notes — FANUC, ABB, KUKA, Universal Robots, Standard Bots and similar pages. These start with a research-method note. We have not independently lab-tested those machines.
Photographs of factory robots are editorial illustrations unless a caption says otherwise. Original diagrams on this site are conceptual; they are not a substitute for a drawing package or a safety review.
Editorial independence
The site may show display advertising through Google AdSense after it is approved. Advertising does not choose which brands appear and does not change a payload number. We are not paid by robot manufacturers for coverage. See the Privacy Policy Editorial standards for cookies and advertising.
Who edits the site
Pages are written and edited by Marcus Chen, a robotics engineer who founded this site in 2023. He is responsible for the technical accuracy of every guide and for keeping specification notes labelled as such.
Marcus Chen
Marcus builds and debugs 6-DOF robot arms — Arduino and ESP32 firmware, inverse kinematics, ROS 2 integration, and the PLC and safeguarding work around an industrial cell. He writes the educational guides and checks that industrial pages stay labelled as specification notes rather than hands-on reviews.

Corrections and Feedback
We get things wrong sometimes — a miswired pin, an outdated ROS 2 package name, a part that's since been discontinued. If you spot an error in a tutorial, please tell us. We correct published articles promptly and credit readers who flag mistakes, if they'd like to be credited.

How we research and label technical content
We distinguish between three types of material: documented specifications, calculations or examples prepared for the article, and hands-on observations from a clearly identified build. A manufacturer specification is not presented as an independent test, and an illustrative calculation is not presented as a measured result.
- Primary sources first: manufacturer documentation, standards bodies and project repositories are preferred for specifications.
- Traceable claims: important figures should have a nearby source or a clear explanation of the calculation used.
- Clear limits: prices, safety requirements and performance depend on configuration, region and date; readers should confirm them before making a purchase or building a machine.
- Corrections: if a source changes or a reader identifies an error, we update the article and explain the correction where it affects the recommendation.
Diagrams marked as editorial illustrations explain a concept; they are not photographs, certification evidence or a substitute for an engineering review.
