What is Langhui E2? Who is it for? Why choose it?
Langhui E2 is a wrist data acquisition device designed for industrial lines, worn by the operator's wrists, to simulate the observation and operational perspective of the robot's end-of-pipe implementer by first person.。It targets automation/process engineers in areas such as automobile manufacturing, electronic manufacturing, heavy machinery, and addresses the acute shortage of high-quality training data for industrial scenes。E2 has an IP67 industrial shield, MIL-STD-810G military marker anti-shock, 3 mm ATE precision, global fast door no jelly effect, thermal plug-in batteries and the EtherCAT/PROFINET industrial agreement, which is the current core integrated data-collection facility designed specifically for the Chinese industrial production line environment。
Product Overview
E2 is the highest-positioned industrially protected equipment in the Ego series.。Its core mission is only one: to collect high-precision, multi-modular operational data from the same end-of-pipe implementer perspective in the real industrial line environment, and to provide reliable institutional data integration capabilities for embodied AI manufacturing。All design decisions -- from the global fast door to thermal plug-in batteries, from the EtherCAT protocol to the depth of structural light -- are built around this goal.。
The above five core parameters constitute fundamental differences between E2 and all other programmes。The engineering significance and actual value of each capability is set out below.。
Which industries does E2 target?
E2 design target users are automated engineers and process engineering on industrial production lines Division。The central challenge they face is how to get robots to learn a new process quickly, instead of spending weeks on traditional teaching programming.。E2 provides them with an entirely new path - to compress the new process import cycle from the perimeter to the sky by collecting high-precision operational data, driving imitation and enhanced learning。
Automotive Manufacturing
Welding workshop arc light, dust, temperature, E2 IP67 protection and global fast door to maintain data integrity in welding track。Spray workshop coating fogging and solvent vapour proliferation, E2 capture spray trajectory and overlapping parameters。On the main line, E2 records the exact sequence of actions, such as grabs, positions and twists, to assist in the assembly of robots with flexible operation training。
Electronics Manufacturing
SMT stickers, precision assembly and PCB testing are extremely demanding for operational accuracy。3mm ATE accuracy combined with structural light depth module of E2 allows accurate capture of metaware pick-up, visual positioning and placement operational data, as well as micro-engineer data such as connector extraction, screw lock payment, and provides quality training data for high-precision assembly robots。
Heavy Machinery
Large parts assembly and suspension operation space large, heavy, vibrating power。E2 MIL-STD-810G military marker resilience guarantees stability in a strong impact environment, a global fast door removes motion blurring during suspension and accurately captures full flow data for large components docking and bolting。

Warehousing and Logistics
E2 captures capture postures, path plans and shelf access action sequences in the smart upgrades of AGV and AMR。Remarkable optimization of mobile robots ' navigational strategies and operational efficiencies in complex warehousing environments through high-quality demonstration data and shorter deployment modulation cycles。
Industrial-Grade Core Capabilities
Global Fastgate: Eliminating Jell-O Effects
A large number of operations in industrial scenes involve fast motion - welding, parts transfer, mechanical arm grab。The traditional Rolling Shutter produces visible Jell-O effects in the shooting of fast motion objects, and objects in the image are stretched, tilted or distorted, which directly results in visual data not being used for model training。E2 carries the Global Shutter RGB camera, and all pixels are exposed at the same time, no matter how fast they move, the frame is clear and non-modified.。It's critical to the accuracy of the next visual sensory algorithm.。
IP67 + MIL-STD-810G: Dust, oil pollution, vibration, high temperature wide coverage
IP67 means E2 is completely dustproof and can be immersed in water for a short time. E2 can be used directly without additional protective shells in environments such as welding workshops (metal dust), machine processing workshops (cooling fluid splatter), and pressure lines (oil cover). MIL-STD-810G military standard certification covers multiple tests of vibration, shock, temperature shock, etc., and E2 is able to maintain structural integrity and functionality in the event of sustained high-frequency vibrations and accidental drops. Operating temperature range -20°C to 60°C. Covers everything from northern winter outdoor heavy work to southern summer hot workshops.
Thermal plug-in batteries: uninterrupted operation
Production data collection often takes hours or even shifts.。In the traditional programme, power consumption of equipment means interruption of collection, data disconnection。E2 Thermal plug-in batteries are designed to allow operators to replace batteries without disrupting the data acquisition process and to achieve a genuine uninterrupted operation。This capability is particularly critical for data collection tasks that require long periods of time to track the same process complete。
EtherCAT / PROFINET: industrial agreements inserted
It's one of the core competencies of E2.。EtherCAT and PROFINET are the two most widely used industrial Ethernet agreements in the field of industrial automation worldwide。E2 natives support these two sets of bonding, which means that it can directly access the existing automated control network of the plant, like a PLC or an industrial sensor, without the need for an additional protocol conversion gateway or intermediate adaptation layer。Operational data collected can interact directly with the production line MES, robotic controllers in real time, significantly reducing deployment costs and complexity of integration degrees。

Industry Background
China's industrial robot stock exceeded 1.5 million.
According to the Industrial Robotics Industry Development Report released by the front line of the Ministry of Industry and Communications, by the end of 2025, China ' s industrial robot holdings had exceeded 1.5 million and were at the international top.。However, in stark contrast to the large equipment base, high-quality sensory-action matching data sets that can be used to train industrial robots for autonomous operation are extremely scarce.。Industrial scene data gaps are much larger than consumer scenes, because industrial data require not only "visibility" but also "preciseness" — the threshold for accuracy, consistency and environmental adaptation is far beyond the capacity of the consumer data acquisition instrument.。
8th Division "AI+ Manufacturing"
In January 2026, the Ministry of Industry and Communications, the Ministry of Science and Technology, among others, jointly issued the "AI+ Manufacturing" Action Programme, which explicitly stated that "the development of high-quality industrial data sets is the foundation of the artificially intelligent manufacturing industry" and that "the development of high-quality industrial data sets is a fundamental project to accelerate the deployment of industrial megamodels and smarts to the manufacturing landscape".。This policy signal means that input from the industrial data acquisition infrastructure will be the core track for the next 3-5 years of intelligent manufacturing upgrading。
Digital twin demand outbreak.
Industrial Twin needs an accurate data map to match the physical line at 1:1。E2 high-level security operations data -- including visual, depth, inertia and time stamp -- are at the core of building a digital twinning system. Source。Virtual debugging and validation of new processes can be achieved in a virtual simulation environment through accurate three-dimensional reconstruction and kinetic analysis of real operating data to eliminate potential risks prior to deployment。The efficiency and quality of Sim-to-Real migration depends directly on the degree to which data collection is consistent with the real scene, and the end-end implementer of E2 has a natural advantage in this dimension。
Why Choose E2?
Professional industrial-level integration programmes
There are no IP67 protections, military markers against earthquakes, global gates, 3mm ATE precision and EtherCAT/PROFINET industrial agreements on the market。E2 is not a compromise for "consumer-grade equipment plus shell" but is dedicated to the design of the industrial landscape from hardware architecture to communications protocols.。
Plug-and-play with ABB/KUKA/FANUC
E2 has been calibrated to be compatible with the protocol for the control of the main industrial robot brands of ABB, KUKA, FANUC, Andokawa, Nagajima.。This means that the operational data collected by E2 can be directly injected into robotic motion planning systems for teaching data enhancement, trajectories optimization and operational strategy learning to form complete closed loops from data acquisition to modelling training to robot deployment.。No custom development, no protocol conversion, open boxes。
Reduction of new process import cycle: from step to step
Traditional teaching and programming methods require professional engineers to prepare movement procedures on a point-by-place basis, and a new line is often programmed for weeks or months.。E2-based imitation learning and enhanced learning paradigms that enable non-professional operators to program robotic missions through natural demonstrations, and compress the import cycle of new processes from the weekly to the parent level。This efficiency improvement is particularly critical to the flexible manufacturing landscape of multiple varieties and small quantities.。

Frequently asked questions
Can E2 use it at the welding workshop?？
Yes. The E2 is rated at the IP67 industrial protection level, fully dustproof and resistant to water ingress. Its system-level anti-electromagnetic-interference design, using multi-layer shielding and filtering technology, ensures stable operation in strong electromagnetic interference scenarios such as welding arcs and modifiers. Meanwhile, the global shutter camera eliminates the jelly effect when the welding gun moves rapidly, exporting clear trajectory data. E2 has been validated in data collection for the aluminium-alloy body welding process at a leading domestic automaker, with stable performance across three shifts of high-intensity operation.
What brands of robots?？
E2 adapted robot brands include ABB (IRC5 / OmniCore controller), KUKA (KR C4 controller), FANUC (R-30iB / R-30iB Plus controller), Yaskawa (YRC1000 controller) and Nachi-Fujikoshi (FD controller)。In addition, E2 supports the ROS2 Industrial framework and the DDS intermediate standard, which theoretically is compatible with any robotic system supporting ROS2。If you have a specific brand compatibility requirement, please contact the Lang Hui Technological Team for an assessment.。
Do you need to shut down the line?？
No. The E2 design philosophy is "non-invasive collection" — it is worn on the operator's wrist and does not affect the normal production process of the production line. The data collection process runs completely in parallel with normal operations, and workers do not need to change their operating habits. At the communication level, the E2 accesses the plant control network via EtherCAT/PROFINET in a "listen-only" mode, without interfering with the normal operation of the existing control system.
