Six Engineering Highlights of the G-Series
These are the design decisions our application engineers reference when recommending a cobot for a new cell.
1. High Speed, Stability & Accuracy
Calibrated benchmarks for high speed, high precision, high flexibility and high intelligence — comparable to industrial-grade six-axis robots.
2. Multiple-Layer Safety Design
XI black-box data recorder, over 100 self-monitoring safety functions, 10-level collision-force protection, and power-off protection that keeps the robot stable when the cable is suddenly cut.
3. Lightweight & Easy to Use
Self-weight-to-payload ratio below 4. The tool-end provides three-color status lights, two function buttons and two bus interfaces, plugging directly into your existing line.
4. Smart Manufacturing Ecosystem
Wired / wireless / 4G / 5G communication and flexible access to MES and the Industrial Internet.
5. Scene-Closer Application Tech
2D and 3D vision, integrated force sensors, mainstream PLCs, servo systems and CNC machines. EtherCAT extension axis enables conveyor-belt tracking and synchronization.
6. Automotive-Grade Quality
Stable long-lifespan operation. Manufacturing system complies with IATF 16949:2016.
Portable Teach Pendant
A 1.5 kg portable teach pendant with emergency-stop hardware, three-color status lights and a graphical programming environment lets operators drag, drop and record motion paths without writing code.

Frequently Asked Questions
Which model should I choose — CR3, CR6, G6 or G12?
Match the payload first. CR3 (3 kg) fits service scenarios such as smart retail and catering. CR6 (6 kg, 924 mm reach) is the cost-effective option for light assembly. G6 (6 kg, automotive-grade) is recommended when IATF 16949 quality is required. G12 (12 kg) suits spray painting, mobile welding and heavier handling.
What is the repeatability and accuracy of the cobots?
All C-series and G-series models offer a repeatability of ±0.03 mm, which is sufficient for screw locking, soldering, vision inspection, dispensing and most assembly tasks.
Which international certifications do the cobots hold?
CE (Europe), FCC (USA), SGS third-party testing, ISO 9001 / ISO 14001 / ISO 45001, and IATF 16949:2016 for the automotive supply chain. TUV Nord and TUV SUD reports are available on request.
Can the cobot integrate with 2D/3D vision and force sensors?
Yes. The G series supports 2D and 3D vision, integrates force sensors, and connects to mainstream PLCs, servo systems and CNC machines. EtherCAT extension axis enables conveyor-belt tracking and synchronization.
How fast is delivery and what does the warranty look like?
C-series models are held in local stock in South China and ship within 5 business days. G-series models are scheduled per order. A standard 12-month warranty is included; extended warranty and on-site service contracts are available.
Do you provide integration services or just the equipment?
Both. Equipment-only orders are welcome for buyers with their own integration team. For turnkey projects we deliver vision, end-of-arm tooling, conveyor integration and acceptance testing under one scope of work.
