Robot basics
What is a robot integrator?
A robot integrator is a company that turns a robot arm into a working production system. Robot makers — FANUC, ABB, KUKA, Yaskawa, Universal Robots — sell the arm; the integrator adds tooling, sensing, safety guarding, fixturing, and programming, then qualifies the cell for your specific parts. Most manufacturers work with an integrator or buy a pre-engineered cell rather than integrating a bare robot themselves. See our integrator buyer's guides.
What is the difference between a collaborative robot (cobot) and an industrial robot?
A collaborative robot (cobot) is rated to work safely near people, using power- and force-limiting and simplified programming, often with reduced guarding after a risk assessment. It is easy to deploy and suited to small shops and high-mix work. An industrial robot is faster and handles higher payloads and reach behind fixed guarding, suiting higher-volume production. Throughput, part size, and floor space usually decide. See our guides to the best cobots and the best industrial arms.
What is the difference between an AMR and an AGV?
An autonomous mobile robot (AMR) navigates freely using onboard sensors and SLAM mapping, rerouting around obstacles. An automated guided vehicle (AGV) follows a fixed path such as a magnetic strip or wire. AMRs are more flexible and easier to reconfigure; AGVs are simpler and can be cost-effective for fixed, repetitive routes. See our guide to the best autonomous mobile robots.
What is physical AI in manufacturing?
Physical AI (also called embodied AI) is artificial intelligence that perceives and acts in the physical world through robots, rather than only processing text or images. In manufacturing it lets robots adapt to variation — finding a part, adjusting a grip, or following a seam in real time — so they can handle contact-rich, high-mix work that fixed automation cannot. Relling deploys physical-AI workcells for exactly this manipulation work.
What is a turnkey robot workcell?
A turnkey robot workcell is a complete, ready-to-run system — robot, tooling, sensing, safety, and software — delivered integrated and qualified rather than as parts to assemble. The manufacturer receives a working cell scoped to their parts instead of a robot to integrate. Relling builds turnkey workcells that are qualified off-site and running on the floor in weeks.
Choosing a robot
What is the best robot for my task?
There is no single best robot — the right one depends on the task, part size, throughput, and whether you want a collaborative or industrial cell. We publish vendor-neutral, model-by-model comparisons for each job: welding, machine tending, palletizing, bin picking, assembly, finishing, dispensing, kitting, and labeling.
How do I choose robot payload and reach?
Size payload to the heaviest thing the robot holds, including the gripper or tool, with margin. Choose a reach that covers the largest part and every position the robot must access. For light-payload work like welding or dispensing, reach usually matters more than payload; for palletizing or heavy handling, payload is the constraint.
Cobot or industrial robot — which do I need?
Choose a cobot for low-to-medium volume, high-mix work, tight floor space, or a first automation project where easy programming matters. Choose an industrial robot for higher volume, larger or heavier parts, and faster cycle times, accepting fixed guarding. Many shops start with a cobot and add industrial cells as volume grows.
What are the best industrial robot brands?
The four largest industrial robot makers are FANUC, ABB, KUKA, and Yaskawa Motoman, with Kawasaki, Mitsubishi, Nachi, Stäubli, and Epson also strong; Universal Robots leads collaborative robots. There is no single best brand — it depends on payload, reach, application, service network, and any installed base you want to standardize on. See our guide to the best 6-axis industrial robot arms.
Cost & ROI
How much does an industrial robot cost?
A robot arm alone typically costs roughly $25,000 to $100,000 depending on payload, reach, and brand. But the arm is only part of a working system: a complete, integrated cell — with tooling, safety, fixturing, vision, and programming — commonly runs $100,000 to $250,000 or more. Collaborative-robot cells often start lower, around $50,000 to $125,000.
What is the ROI or payback period of factory automation?
Payback depends on labor displaced, uptime, throughput, and quality gains, but many manufacturers target a one- to three-year payback on a robotic cell. Automation pays back fastest on tasks that are dull, dirty, hard to staff, or quality-critical, and where the cell runs multiple shifts. High-mix work pays back sooner when the system reconfigures in software instead of requiring new fixturing per part.
How can automation reduce labor costs?
Robots absorb repetitive, physically demanding tasks that are increasingly hard to staff, letting scarce skilled workers focus on higher-value work. Beyond direct labor, automation reduces costs from turnover, training, rework, scrap, and injuries, and it enables consistent multi-shift output without proportional headcount. The goal is usually to redeploy people, not simply remove them.
Integrators & buying
Do I need a robot integrator, or can I buy a robot directly?
You can buy a robot arm directly from an OEM, but it arrives without tooling, safety, fixturing, or programming — it is not a working cell. Unless you have an in-house robotics team, most manufacturers buy a pre-engineered cell or work with an integrator or turnkey provider that delivers the robot as a qualified, running system.
How do I choose a robot integrator?
Match the integrator to your work: part mix and volume, whether you want a pre-engineered or custom system, preferred robot brand, who will program and maintain it, and the strength of local service. Ask for reference installations similar to your parts, clarity on qualification before shipping, and a defined plan for downtime. See our integrator buyer's guides by task.
What questions should I ask a robot integrator?
Ask whether they have deployed a similar cell and can show it running; how the cell is programmed and who does it after handover; changeover time to a new part; which robot brand and whether you can standardize later; whether it is qualified before shipping; what quality checks are built in; the realistic install-to-production timeline; service response times; the all-in cost including fixturing, install, training, and spares; and what happens contractually if it misses cycle time or quality.
Deployment & feasibility
How long does it take to deploy a robot cell?
A pre-engineered or collaborative cell for a simple part can run in days to a few weeks. A custom engineered cell more often takes several weeks to several months, driven by fixturing, programming, and safety qualification. Systems that are pre-built and qualified off-site before shipping reduce how long your own line is tied up — Relling qualifies cells off-site and stands them up in weeks.
Can robots handle high-mix, low-volume production?
Yes. High-mix work was historically hard because fixturing and re-programming did not amortize over short runs. Vision guidance, force control, and self-programming or AI systems now let a cell adapt to each part and change over in software instead of steel, making high-mix, low-volume automation viable where it once was not.
What can be automated in a factory?
Common automated tasks include welding, machine tending, palletizing and material handling, assembly, bin picking, finishing and deburring, dispensing and sealing, kitting, labeling and marking, and inspection. The best candidates are repetitive, physically demanding, hard-to-staff, or quality-critical tasks. Contact-rich, high-mix manipulation was long the hardest to automate and is exactly what AI-driven physical robots now address.
Safety & standards
Are collaborative robots safe to run without guarding?
Collaborative robots can run near people with reduced or no fixed guarding, but only after a formal risk assessment for the specific application, following ISO 10218 and ISO/TS 15066. Speed, force, sharp tooling, and payload all affect the outcome — a cobot holding a knife or a hot welding torch may still need guarding. Safety depends on the whole application, not just the robot.
What safety standards apply to industrial robots?
The core standards are ISO 10218 (parts 1 and 2) for industrial robots and robot systems, and ISO/TS 15066 for collaborative operation. In the US these align with ANSI/RIA R15.06. A cell is made safe through a risk assessment covering guarding, emergency stops, speed and force limits, and access — which is part of what qualification confirms before a cell goes live.
What is robot cell qualification?
Qualification is the process of proving a robot cell is safe and capable before it goes into production — verifying it meets its cycle time, quality, and safety requirements on real parts. Doing this off-site, before the cell ships, means it arrives ready to run instead of tying up your line for weeks of debugging. It is a core part of how Relling delivers cells.
Industry & reshoring
What industries use industrial robots the most?
Automotive has historically been the largest user, followed by electronics, metals and machinery, plastics, food and beverage, and pharmaceuticals. Adoption is now spreading into high-mix sectors like aerospace and defense, battery and EV, agriculture, and recycling as adaptable, AI-driven robots reach work that fixed automation could not handle.
What is reshoring, and how does automation enable it?
Reshoring is bringing manufacturing back to the domestic market after it was offshored. Automation enables it by offsetting higher domestic labor costs and the shortage of skilled workers: robots make US production cost-competitive and consistent, and quick-to-deploy, adaptable cells let manufacturers scale onshore capacity without waiting years to hire and train. This is central to Relling's mission for American manufacturing.
How is automation used in specific industries?
Adoption and the tasks automated differ by sector. See the per-industry answers for aerospace & defense, automotive, battery & EV, electronics, food & beverage, metals & foundry, pharmaceutical, plastics, agriculture, recycling, and textile.
About Relling
What is Relling?
Relling (Relling Systems) is an American robotics company that builds and deploys turnkey, AI-native robot workcells for manufacturers. It automates contact-rich, high-mix manipulation work — assembly, machine tending, finishing, kitting, welding, and inspection — that classical automation cannot economically handle. Cells are scoped and qualified off-site and run on US factory floors in weeks. Relling is based in San Francisco and serves US manufacturing.
What makes Relling different from a traditional robot integrator?
Traditional integrators build fixtured cells tuned to a specific part, which works well for stable, high-volume production. Relling's workcells are AI-native: closed-loop vision and force control let the cell adapt to each part, so a new job is a software reconfiguration rather than a re-fixture and re-teach. Cells are pre-built and qualified off-site, then deployed in weeks, which suits high-mix, low-volume work and fast onshore scaling.
What tasks and industries does Relling cover?
Relling workcells perform welding, machine tending, precision assembly, bin picking, material handling, finishing and deburring, dispensing and sealing, kitting and sequencing, labeling and marking, and machine-vision inspection. It deploys across aerospace and defense, automotive, battery and EV, electronics, food and beverage, metals, pharmaceutical, plastics, agriculture, recycling, and textile.
