Custom Robotic Cells

I've been building robotic cells since the early 2000s, and here's what I can tell you with certainty: the robot is the easy part. Any competent integrator can bolt a FANUC M-20iD to a pedestal and teach it a pick-and-place routine. What separates a cell that runs at 95% OEE from one that limps along at 65% is everything around the robot—the fixturing, the part presentation, the end-of-arm tooling, the safety architecture, and the controls integration that ties it all together into a production-ready system.

That's what AMD Machines does. We've shipped over 2,500 custom automation systems in 30+ years, and a significant portion of those are robotic cells purpose-built for specific manufacturing applications. We don't sell robots. We sell complete, turnkey production systems that happen to use robots as the core motion platform.

What Makes a Robotic Cell Different from a Robot

This is a distinction that matters, especially if you're making your first automation investment. A robot is a six-axis (or four-axis, if it's a SCARA) articulated arm that moves through programmed positions. A robotic cell is a complete production system: the robot, plus custom end-of-arm tooling, fixtures, safety enclosures, part presentation systems, vision, sensors, PLC controls, HMI, and all the integration work to make those components function as a single coordinated machine.

Think of it this way: the robot is the engine, but the cell is the entire car. And just like you wouldn't buy an engine and expect to drive it home, you shouldn't buy a robot and expect it to produce parts without significant engineering around it.

When we design a custom robotic cell, we're solving a manufacturing problem—not just programming a robot. The process starts with your part, your cycle time target, your quality requirements, and your facility constraints. The robot brand and model come later, after we've determined the reach, payload, speed, and accuracy requirements that the application demands.

Choosing the Right Robot Platform

We're brand-agnostic, and that's a deliberate choice. Every robot manufacturer has strengths, and locking into a single brand means you're compromising on applications where another platform would deliver better performance, reliability, or value. Here's how we think about robot selection after 30 years of integration experience:

FANUC

FANUC is our most-integrated brand, and for good reason. Their reliability record is unmatched—we have FANUC robots in the field with 80,000+ hours on the original gearboxes. The R-30iB Plus controller is mature, well-documented, and integrates cleanly with Allen-Bradley PLCs via EtherNet/IP.

Best for: Arc welding (Arc Mate series), machine tending (M-20iD, M-710iC), heavy material handling (M-900iB at 700 kg payload), and any application where uptime is the primary metric. FANUC's iRVision integrated vision eliminates the need for separate vision controllers in many applications.

ABB

ABB robots have the best motion algorithms in the business. Their TrueMove and QuickMove technologies produce smoother, faster paths than any other brand—which translates directly into shorter cycle times on complex path applications like dispensing, deburring, and spray coating.

Best for: High-speed picking (IRB 360 FlexPicker at 150 picks/min), path-critical applications, and multi-robot coordination using MultiMove. The OmniCore controller is fast and capable, though it requires more networking expertise to integrate than FANUC's platform.

KUKA

KUKA builds the heavy lifters. Their KR QUANTEC series spans 120–300 kg payload with reaches up to 3,900 mm, and the KR FORTEC handles up to 600 kg. We've deployed KUKA robots extensively in automotive body shops and heavy equipment manufacturing where payload and reach are non-negotiable.

Best for: Heavy payload applications (150+ kg), large work envelopes, automotive body-in-white, and applications requiring the robot to manipulate large weldments or castings.

Yaskawa Motoman

Yaskawa's arc welding robots—particularly the AR series—deliver exceptional welding quality at a competitive price point. Their DX200 controller handles coordinated motion between the robot and external axes (positioners, slides) very well, which is critical for complex welding applications.

Best for: Arc welding (AR1440, AR2010), palletizing (PL-series with 800 mm/s speed), and applications where coordinated multi-axis motion is required.

Collaborative Robots (Cobots)

For lower-force applications where operators work alongside the robot, we integrate Universal Robots (UR10e, UR20) and FANUC CRX series cobots. Cobots are not a replacement for industrial robots—they're slower, lower payload, and less precise. But for applications under 20 kg payload where you need human-robot collaboration without hard guarding, they're the right tool.

When cobots make sense: Low-volume assembly operations, machine tending with operator interaction, quality inspection assist, and applications where floor space prohibits a full safety enclosure.

Anatomy of a Production-Ready Robotic Cell

Every robotic cell we build includes these core subsystems, each engineered for the specific application:

End-of-Arm Tooling (EOAT)

The EOAT is arguably the most critical component in the cell. It's the interface between the robot and your parts, and a poorly designed gripper will destroy your OEE faster than anything else. We design EOAT in-house using Schunk PGN-plus pneumatic grippers, custom vacuum tooling with Piab vacuum generators, and servo-electric grippers from Zimmer for force-sensitive applications.

For multi-part or multi-operation cells, we use Schunk SWS quick-change systems or ATI tool changers, allowing the robot to swap between different grippers in under 3 seconds. On a recent material handling cell, we designed a dual-gripper EOAT that picks a finished part from the CNC chuck and loads a raw blank in a single robot motion—cutting door-to-door cycle time from 14 seconds to 7.8 seconds.

Safety Systems

Every cell ships fully compliant with RIA 15.06 (ANSI/RIA R15.06-2012) and ISO 10218-2. That's not optional—it's the law. Our standard safety architecture includes:

• Perimeter guarding with SICK or Banner safety-rated interlocked doors
• Safety-rated monitored stop (SRS) zones using the robot controller's built-in safety functions
• Light curtains (SICK deTec4 or Banner EZ-SCREEN) for operator load/unload zones
• Area scanners (SICK microScan3 or Omron OS32C) for zone-based speed reduction near collaborative workspaces
• Safety PLC (Allen-Bradley GuardLogix or Pilz PNOZ) for safety logic
• Lock-out/tag-out provisions per OSHA 29 CFR 1910.147

We perform a risk assessment per RIA TR R15.306 on every cell and deliver a documented safety validation with the machine.

Vision Integration

Most modern robotic cells include some level of machine vision, whether for part location, quality inspection, or process verification. We're experienced with all major platforms:

• Cognex In-Sight and VisionPro — Our go-to for complex inspection applications. PatMax pattern matching and edge-based tools are best-in-class.
• Keyence CV-X and XG-X series — Excellent for high-speed inline inspection with simple setup.
• FANUC iRVision — Integrated directly into the robot controller, eliminating external hardware. Ideal for 2D and 2.5D part location.
• 3D vision — Photoneo, Zivid, and FANUC 3DV for bin picking and random part orientation.

On a recent electronics manufacturing cell, we used a Cognex In-Sight 9912 with 12 MP resolution to inspect solder paste deposits on PCB assemblies. The system catches bridging, insufficient paste, and misalignment at rates under 500 ms per board—something manual inspection missed on roughly 2% of production.

Controls Architecture

We standardize on Allen-Bradley ControlLogix and CompactLogix platforms for cell-level control, with Rockwell PanelView Plus or FactoryTalk View HMI. The PLC serves as the cell master, coordinating robot motion, safety systems, vision triggers, and I/O. Communication between the robot controller and PLC runs over EtherNet/IP (FANUC, Yaskawa) or PROFINET (KUKA, ABB).

For Industry 4.0 connectivity, every cell ships with OPC UA capability and optional MQTT publishing for real-time production data. We've integrated robotic cells with SAP, Plex, Ignition SCADA, and custom MES platforms using REST APIs and direct SQL writes. Explore the industries using robotic automation.

Real-World Application: Automotive Transmission Component

A Tier 1 automotive supplier approached us with a machine tending application that was killing their production schedule. They had two CNC lathes and a vertical mill producing transmission shafts, with three operators hand-loading parts across two shifts. Cycle time variability was 15%, scrap from load errors ran 2.3%, and they couldn't find operators to cover third shift.

We designed a dual-robot cell with two FANUC M-20iD/25 robots, each equipped with dual-gripper EOAT for simultaneous load/unload. A FANUC iRVision 2D camera locates raw blanks on an infeed conveyor, and a Cognex In-Sight 7802 performs dimensional verification on finished parts before they exit the cell.

The cell handles the complete workflow: pick raw blank from conveyor, load CNC lathe #1, unload finished Op 10, transfer to lathe #2, unload Op 20, transfer to VMC for Op 30, unload finished part, present to vision inspection, place on outfeed conveyor or reject chute.

Results: Door-to-door cycle time reduced from 48 seconds to 31 seconds (35% improvement). Scrap from load errors dropped from 2.3% to 0.1%. The cell runs three shifts with a single operator monitoring all three machines. ROI payback was achieved in 14 months, driven primarily by the addition of third-shift capacity that the manual operation couldn't staff.

Real-World Application: Medical Device Packaging

A medical device manufacturer needed to package sterile catheter assemblies into thermoformed trays with precise placement orientation. The product had 6 variants with different tray configurations, and FDA 21 CFR Part 11 traceability was mandatory. Their manual line required 4 operators per shift and couldn't maintain the placement consistency required for downstream automated lidding.

We built a cell around an ABB IRB 1200-5/0.9 robot with a custom vacuum EOAT and Cognex VisionPro guidance. The system reads a 2D DataMatrix barcode on each catheter assembly, verifies the product variant against the active recipe, picks the assembly from a conveyor, and places it into the correct tray pocket with ±0.5 mm accuracy.

A second Keyence CV-X camera verifies tray fill completeness before the tray advances to the lidding station. Every placement event—including the barcode data, robot position, vision match score, and timestamp—is recorded to a SQL database with 21 CFR Part 11-compliant audit trails.

Results: Placement accuracy improved from ±3 mm (manual) to ±0.4 mm (robotic). Throughput increased to 32 trays per hour, a 280% improvement. Variant changeover takes 90 seconds (recipe selection on the HMI). The system eliminated all tray fill errors, which had been generating approximately $180,000/year in rework and scrap costs.

Real-World Application: Heavy Equipment Weld Cell

A heavy equipment manufacturer was hand-welding structural brackets—large, heavy weldments with 40+ inches of continuous fillet welds per part. Welder availability was their bottleneck; they couldn't hire enough certified welders to meet demand.

We deployed a KUKA KR CYBERTECH with a Fronius TPS 500i CMT welding package on a 3-axis servo positioner. The positioner rotates the 85 kg weldment through optimal orientations while the robot welds, maintaining flat and horizontal positions to maximize deposition rates and minimize distortion.

Lincoln Electric's WeldScore monitoring system tracks arc voltage, current, wire feed speed, and travel speed in real time, comparing every weld against qualified parameters. Touch sensing and through-arc seam tracking compensate for part-to-part variation in the flame-cut brackets.

Results: Weld cycle time reduced from 22 minutes (manual) to 9.5 minutes (robotic)—a 57% reduction. First-pass weld acceptance rate improved from 88% to 99.2%. One operator now loads/unloads parts while the robot welds, replacing two full-time certified welders per shift. The cell achieved ROI in 11 months, with the largest savings coming from eliminated rework and the ability to meet delivery schedules without overtime.

The ROI Case for Robotic Cells

Here's the framework we use when helping customers build their internal justification. Every robotic cell ROI story has four chapters:

Chapter 1: Direct labor savings. This is the biggest line item in most cases. A robotic cell that replaces 2–3 operators per shift at a fully burdened cost of $55,000–$65,000 per year saves $110,000–$195,000 per shift annually. On a two-shift operation, that's $220,000–$390,000/year.

Chapter 2: Quality cost reduction. Calculate your current scrap rate, rework labor, customer chargebacks, and sorting costs. We typically see robotic cells reduce scrap by 60–90% compared to manual operations. On a product with $12 in material cost running 300,000 units/year with a 2.5% scrap rate, dropping to 0.3% saves $79,200/year in material alone—before counting rework labor and customer penalties.

Chapter 3: Throughput and capacity. If you're capacity-constrained, the revenue impact of adding a third shift or increasing parts per hour can dwarf the other savings. We've seen robotic cells unlock $2M+ in annual revenue that customers were leaving on the table due to labor-limited capacity.

Chapter 4: Risk reduction. Ergonomic injuries, OSHA citations, and workers' compensation claims carry real costs. Removing operators from repetitive, hazardous, or ergonomically challenging tasks reduces your liability exposure and improves employee satisfaction.

For a typical single-robot cell in the $250,000–$500,000 range, we see payback in 12–18 months on a two-shift operation. Multi-robot cells in the $500,000–$1.2M range typically pay back in 14–24 months. Three-shift and high-volume operations often achieve payback in under a year.

Common Challenges and How We Solve Them

"We've never had a robot before—we don't have the skills to maintain it." We provide comprehensive operator and maintenance training with every cell. FANUC and ABB both offer excellent training programs at their regional facilities. More importantly, modern robots are remarkably reliable—FANUC publishes MTBF figures exceeding 80,000 hours. Routine maintenance is grease changes and battery replacements, not rocket science.

"Our parts vary too much for a robot to handle." This is where vision integration earns its keep. With 2D or 3D vision guidance, robotic cells adapt to part variation in real time. We've deployed cells that handle ±5 mm part location variation and ±3° orientation variation without fixturing changes. For extreme variability, bin picking with 3D vision handles completely random part orientations.

"We can't justify the cost for our volumes." Robotic cells are more accessible than most people think. A single-robot machine tending cell with a FANUC CRX cobot can start under $150,000 for simple applications. And the math works at lower volumes than you'd expect—if you're paying two operators $55K/year each, a $200K cell pays for itself in under two years even at modest production volumes.

"Our product mix changes frequently." Recipe-driven programming and quick-change tooling make robotic cells surprisingly flexible. We design cells to handle defined product families with changeover times under 5 minutes. Some cells we've built handle 30+ variants with no physical changeover at all—just recipe selection on the HMI.

"We had a bad experience with automation before." We hear this more often than we'd like, and it usually traces back to poor integration—not the robot itself. That's why we build and fully debug every cell at our facility using your production parts before it ships. You witness the factory acceptance test, and we don't ship until the cell meets agreed-upon cycle time and OEE targets. Learn more about our process optimization approach to ensuring success.

Frequently Asked Questions

What size robot do I need for my application?

Robot sizing depends on three factors: payload (the weight of your part plus the EOAT), reach (how far the robot needs to extend), and speed (cycle time requirements). As a rule of thumb, choose a robot with a payload rating at least 25% above your maximum load to maintain full speed capability. A FANUC M-20iD handles 25 kg at 1,831 mm reach. A FANUC M-710iC handles 50 kg at 2,050 mm. We always model the application in simulation software (ROBOGUIDE or RobotStudio) to verify reach and cycle time before committing to a robot model.

How long does it take to deploy a robotic cell?

A straightforward single-robot cell—machine tending, for example—takes 12–16 weeks from purchase order to site acceptance. Multi-robot cells with custom tooling and vision integration typically take 16–24 weeks. Complex cells with validation requirements (medical, aerospace) may take 24–32 weeks. We provide detailed Gantt charts during the proposal phase.

Can I add more robots or stations to the cell later?

Yes, if we plan for it up front. We routinely design cells with expansion provisions—pre-wired I/O, reserved PLC capacity, and floor space allocations for future robots or stations. Adding a robot to an existing cell that wasn't designed for expansion is possible but significantly more expensive, so it's always better to discuss your roadmap during the design phase.

What ongoing maintenance does a robotic cell require?

Robots themselves require minimal maintenance: grease replenishment every 3–5 years (depending on duty cycle), controller battery replacement annually, and periodic cable inspection. The more maintenance-intensive components are EOAT (gripper pads, vacuum cups, sensors) and part presentation systems (conveyors, feeders). We provide detailed PM schedules and stock critical spare parts for every cell we deliver.

What's the difference between a robotic cell and a cobot cell?

Industrial robotic cells use full-speed robots (up to 2,000 mm/s) inside safety-guarded enclosures. Cobot cells use speed- and force-limited robots that can operate near humans without hard guarding. Industrial cells are faster, more precise, and handle heavier payloads. Cobot cells are simpler to deploy, take less floor space, and cost less—but they're limited to roughly 20 kg payload and 1,000 mm/s speeds. We'll recommend the right approach based on your cycle time, payload, and floor plan requirements.

Do you provide simulation before building the cell?

Every multi-robot cell and every complex single-robot cell goes through offline simulation using FANUC ROBOGUIDE, ABB RobotStudio, or KUKA.Sim before we cut a single piece of steel. The simulation verifies reach, cycle time, collision avoidance, and multi-robot coordination. We share simulation videos with you during the design review phase so there are no surprises.

How do robotic cells connect to our factory network?

All our cells ship with Ethernet connectivity and support EtherNet/IP, PROFINET, or EtherCAT depending on your facility standard. For production data, we provide OPC UA server capability and optional MQTT publishing. HMI data can be pushed to Ignition SCADA, FactoryTalk, or custom dashboards. We've integrated cells with SAP, Plex, IQMS, and custom MES platforms using SQL, REST APIs, and flat-file exchanges. Our digital twins and simulation services can further enhance connectivity and operational visibility.
