SZGH-BCi10 | 10 kg Heavy-Payload Collaborative Robot — 1,350 mm Reach, No Safety Fence

SZGH-BCi10 / BCk10: Heavy-Payload Collaborative Robot for Large-Reach Industrial Applications

The SZGH-BCi10 is the workhorse of the BC i Series mid-to-large arm family — a 6-axis collaborative robot engineered for system integrators and factory automation managers who need a 10 kg payload at 1,350 mm reach without sacrificing collaborative safety. At a reach-to-payload ratio that outperforms most comparable-class cobots, the BCi10 covers palletizing cells, heavy subassembly, robotic welding fixtures, and full-line spray booth integration — all without a safety fence, enabling genuine human-robot collaboration in mixed workspaces. The robot supports the full SZGH open communication stack: Ethernet, Modbus-RTU/TCP, Profinet (optional), SDK (C/C++/Lua/Python), ROS1/ROS2, and a 32-channel I/O architecture (16 general + 16 safety-rated per direction) that connects directly to Siemens, Omron, or Mitsubishi PLCs out of the box.

5 Core Advantages of the BCi10

No Safety Fence — 10 kg Heavy Payload in Collaborative Workspaces

Most industry cobots that reach 10 kg payload at 1,350 mm arm span require a hard safety fence, immediately negating the flexibility benefit of a collaborative robot. The BCi10 achieves PL=d, CAT 3 safety certification with 10-level configurable collision detection, enabling genuine mixed operations — operators can hand-feed parts, inspect workpieces, or perform fixture changes within the robot's working envelope without halting production. For system integrators designing flexible manufacturing cells, eliminating the fence reduces footprint by 15–30%, lowers cell construction cost, and dramatically shortens reconfiguration time when switching between product lines.

1,350 mm Reach — Industry-Leading Arm Span at 10 kg Class

Within the 10 kg collaborative robot segment, a 1,350 mm reach is a meaningful differentiator. Competing platforms in this payload range typically peak at 1,200–1,300 mm, limiting their ability to service large pallet patterns, wide conveyor spans, or multi-fixture cells without repositioning the robot base. The BCi10's 1,350 mm reach, combined with ±360° joint range on all six axes and any-angle mounting, allows integrators to cover larger work envelopes from a single base location — reducing the total number of robot units required per line and lowering integration cost per part. For large-scale collaborative robot arm applications in palletizing and heavy assembly, this reach advantage directly translates to faster ROI.

Open System — SI-Ready Integration from Day One

The BCi10 is designed for rapid system integration. The SZGH open architecture provides a complete API documentation package, standardized Modbus and Profinet interfaces, and SDK support for C, C++, Lua, and Python — the four languages most commonly used in factory automation software stacks. Native ROS1/ROS2 support enables seamless connection to vision-guided robotics pipelines and mobile robot (AMR/AGV) coordination layers. Pre-validated integration profiles are available for Siemens S7/TIA Portal, Omron NX/NY series, Keyence vision systems, and ATI/Bota force-torque sensors, meaning most integrators can achieve initial PLC handshake within hours, not days. This open ecosystem is why the BCi10 is a preferred platform for system integrators building multi-vendor automation lines.

16-Channel Safe I/O — Industrial-Grade Safety Signal Handling

The 16-channel safety-rated I/O (16 DI + 16 DO, safety-rated) in the BCi10 control box goes well beyond the 4–8 channel safety I/O typical of lighter-duty cobots. This capacity supports complex safety architectures: dual-channel emergency stop loops, safety door interlock monitoring, operator presence detection (via safety mat or light curtain), robot enable/disable handshakes with PLC safety modules, and simultaneous coordination of multiple safety zones in a single cell. For automotive, electronics, and logistics lines where safety PLC certification is a customer requirement, having 16 safety channels pre-wired in the control box removes a major integration barrier. Analog I/O (4×AI, 4×AO) additionally supports direct interface with force sensors, pressure transducers, and variable-speed conveyors.

6–12 Month ROI with Domestic Core Components

The BCi10's domestic-sourced core components — servo drives, encoders, and structural castings manufactured in China — provide two strategic advantages for customers in Southeast Asia, South Asia, and Latin America: a delivered cost 20–35% below comparable European or Japanese platforms at the same payload class, and local spare-parts availability that reduces maintenance lead time to days rather than weeks. SZGH's 12-month warranty, combined with a regional distributor network across 40+ countries, supports ROI targets in the 6–12 month range for high-cycle applications (palletizing, assembly, spray coating) where a single BCi10 typically replaces 1.5–2 FTE operators. A 10 kg collaborative robot no safety fence configuration further reduces amortized cell construction cost compared to fenced alternatives.

Customer Perspective — Fannie Chen, CEO, SZGH

"I want to share a recent project that illustrates why we built the BCi10 the way we did. A system integrator based in Cebu, Philippines — running a 12-line electronics PCB chassis assembly facility — came to us after evaluating three European cobot brands. Their core constraint: they needed a 10 kg arm that could reach across a 1,280 mm conveyor span, connect via Python SDK to their existing MES within two weeks, and carry CE+UL certification for the customer audit. We deployed six BCi10 units across two lines. API integration was completed in nine days — the Python SDK's documented endpoints for joint control, I/O state polling, and trajectory execution meant their software team could work in parallel with the mechanical install. Cycle time per chassis dropped from 48 seconds (manual) to 31 seconds. With three-shift operation, the customer projected payback within eight months. For SI teams dealing with tight commissioning windows, the BCi10's open architecture is not a marketing claim — it is the reason projects like this stay on schedule."

Control System

The BCi10 runs the SZGH GRC (Guanhong Robot Controller) platform, purpose-built for industrial collaborative deployment. The controller features a real-time motion kernel with sub-millisecond trajectory interpolation, enabling smooth path execution at up to 4.0 m/s linear TCP speed even during complex multi-axis coordinated moves. The teach pendant (7-inch touchscreen, IP54-rated) provides drag-teaching, waypoint programming, and one-click I/O test functions that allow non-specialist operators to set up simple pick-and-place tasks without programming knowledge. For advanced SI users, the GRC exposes a full REST-style API over Ethernet, Modbus register maps for PLC integration, and a Profinet device profile (optional license) compatible with Siemens TIA Portal V15+. The controller also supports SZGH's optional force-torque feedback module for compliant assembly tasks requiring contact force monitoring down to 1 N resolution.

BCk10 users benefit from the same control capabilities in a compact wall-mount or DIN rail-mount form factor (380×280×100 mm), making it particularly suitable for space-constrained cells, collaborative cells mounted to AGV platforms, or retrofit installations where floor cabinet space is unavailable.

Safety Certifications — Plain Language

CE (European Conformity): The BCi10 meets the EU Machinery Directive (2006/42/EC) and relevant harmonized standards for collaborative robot safety. This certification is required for legal sale and deployment in all EU/EEA member states and is widely accepted as a baseline safety benchmark by multinational manufacturers globally.

UL (Underwriters Laboratories, USA): UL certification confirms that the BCi10 has been independently tested against North American electrical safety standards. Required for deployment in the United States and Canada, and recognized as a quality signal by procurement teams worldwide.

KCs (Korea Certification): KCs marking certifies conformity with Korean electrical and safety standards, enabling direct deployment in South Korean manufacturing facilities without additional local approval processes.

PL=d, CAT 3 (ISO 13849): This is the robot's functional safety rating — the most important certification for collaborative operation without a safety fence. PL=d means the safety function has a high probability of performing correctly on demand (average probability of dangerous failure per hour: 10⁻⁷ to 10⁻⁶). CAT 3 means the safety system is designed so that a single fault does not cause loss of safety function. In practice, this means the BCi10's collision detection, emergency stop, and safety I/O circuits meet the requirements for collaborative deployment in most industrial safety assessments without additional engineered safeguards — subject to a site-specific risk assessment as required by ISO/TS 15066.

Warranty: 12 months from delivery, covering manufacturing defects in robot arm and control system. SZGH regional service partners provide on-site support in 40+ countries.

Frequently Asked Questions

Q1: Is a 10 kg cobot without a safety fence genuinely safe for operators working nearby?

Yes, when deployed in accordance with ISO/TS 15066 collaborative robot safety guidelines and a site-specific risk assessment. The BCi10 holds PL=d, CAT 3 certification (ISO 13849), which is the internationally recognized standard for collaborative robot safety functions. The 10-level configurable collision detection allows the sensitivity to be tuned to the specific task and operating environment. SZGH provides risk assessment documentation templates and application-specific safety configuration guides for common deployment scenarios including palletizing, assembly, and spray coating cells.

Q2: Can the BCi10 connect directly to our existing PLC and SCADA system?

Yes. The BCi10 supports Modbus-RTU, Modbus-TCP, and optional Profinet fieldbus natively. Over 250 pre-mapped Modbus registers cover joint states, TCP position, velocity, I/O status, error codes, and program control — meaning most Siemens, Omron, or Mitsubishi PLCs can read robot status and issue motion commands without custom middleware. For Siemens TIA Portal users, SZGH provides a ready-made GSD file and Add-In for drag-and-drop integration. SCADA integration via OPC-UA is available through the Ethernet API.

Q3: Can the 16 safety I/O channels be configured for emergency stop and safety door signals?

Yes. The 16 safety-rated DI and 16 safety-rated DO channels in the control box are fully configurable and support dual-channel emergency stop loops (meeting EN ISO 13850 requirements), safety door/gate interlock monitoring, operator presence detection (safety mat, light curtain), robot enable/disable handshakes with safety PLC modules, and zone-based speed reduction triggers. Safety I/O configuration is performed via the teach pendant's safety configuration wizard or via the API for automated safety system commissioning. Full IEC 62061/ISO 13849 documentation for the safety I/O subsystem is available on request.

Q4: Is the 1,350 mm reach sufficient for standard pallet patterns?

For standard EUR-pallet (1,200×800 mm) and GMA-pallet (1,219×1,016 mm) patterns, the BCi10's 1,350 mm reach covers the full pallet footprint from a centrally positioned base when the robot is mounted at appropriate height. For larger pallet patterns or when reaching across full pallet depth plus stacking height simultaneously, a reach simulation in SZGH's offline programming software is recommended. In most 25 kg box palletizing scenarios tested in SZGH application labs, the 1,350 mm arm covers 4-layer palletizing on EUR pallets without base repositioning.

Q5: How complete is the SDK documentation?

SZGH provides full API reference documentation (C/C++/Lua/Python), covering every function call with parameter descriptions, return types, error codes, and worked examples. The documentation package includes a commissioning guide, a Modbus register map PDF, ROS package README files, sample projects for common applications (pick-and-place, palletizing, conveyor tracking, force-guided assembly), and a troubleshooting guide. Documentation is maintained in English, Chinese, and Spanish. Updates are released with each firmware version. Access the documentation portal through szghtech.com or contact export02@szghtech.com for the SI integration bundle.

Q6: What are the mounting requirements and base fixing specifications?

The BCi10 arm (38.5 kg) mounts via a standard ISO 9283 flange pattern with M8 bolts (6×, 50 mm bolt circle). Any-angle mounting — floor, wall, ceiling, and inclined — is supported without payload derating. The base must be capable of handling the reaction forces generated at maximum payload and speed; SZGH provides a base design guideline document specifying minimum rigidity requirements for concrete, steel, and aluminum extrusion base structures. The BCi10 control box (floor-standing, 380×350×265 mm) requires a 230×230 mm footprint, or the BCk10 compact controller (380×280×100 mm) can be wall-mounted to eliminate floor space requirements entirely.

Q7: What is the spare parts and after-sales service situation?

SZGH maintains a regional spare parts inventory across key hubs in Southeast Asia, South Asia, Europe, and Latin America. Common wear items (end-of-arm wrist seals, teach pendant cables, I/O terminal blocks) are typically available from regional stock within 3–5 business days. Major mechanical assemblies (joint modules) are available from the Shenzhen factory with standard air freight lead time of 5–7 business days to most destinations. On-site service is available through SZGH's authorized service partner network in 40+ countries. Remote diagnostics via Ethernet API allows SZGH engineers to perform fault diagnosis, firmware updates, and parameter adjustments without a physical site visit for most software-related issues.

Q8: What is the typical ROI timeline for a BCi10 deployment?

In high-cycle applications (palletizing, assembly, machine tending) operating two or three shifts, the BCi10 typically achieves payback in 6–12 months. The key cost drivers are: robot unit price + integration cost (reduced by open SDK and pre-validated PLC profiles), labor cost displacement (BCi10 typically replaces 1.5–2 FTE in three-shift operation), and cell reconfiguration frequency (no safety fence reduces changeover time and cost significantly). SZGH provides an ROI calculation worksheet on request, customizable to specific labor costs, cycle times, and integration scenarios.
