For the connector industry, humanoid robots are no longer a distant vision.
Xiaomi has just wrapped up 4 months of real-world factory testing—proving industrial viability. Tesla, meanwhile, is breaking ground on million-unit production lines. Mass production is no longer a question of 'if' but 'when.'
As OEMs transition from prototypes to pilot production, upstream connector demand is shifting from speculation to actual orders.
So here's the million-dollar question: How big is the upside for connectors? And how much of it can Chinese suppliers capture?
What's your take—are humanoid robots the next growth engine for our industry?"
First, let's talk about humanoid robots—where exactly do they stand right now?
Before we dive into connectors, we first need to clarify one thing: are humanoid robots truly being deployed on the ground today, or is this just another round of hype?
Globally, two main development paths are emerging.
One is the approach represented by Xiaomi—'make it useful first, then make it universal.'
Xiaomi's philosophy is pragmatic. Instead of aiming for a do-it-all machine from day one, they start with a specific application scenario, dive deep, and iterate gradually.
The chosen scenario? Their own automobile factory. In early 2026, Xiaomi deployed its humanoid robots at the Beijing Yizhuang Xiaomi EV Superfactory, where they are taking over repetitive workstations in the final assembly shop
Four months in, the most notable achievement is the self-tapping nut insertion station, where the success rate climbed from 90.2% to 98%. This station requires the robot to overcome magnetic interference while performing visual recognition, force control feedback, and precise alignment—a technically demanding task.
Of course, judging from the publicly available video footage, the production rhythm still lags behind that of skilled human workers. And for now, the robots are only handling a few specific workstations—still a long way from being 'universal.'
But here's the key: it's already out of the lab and operating continuously in a real industrial environment. And that step matters.
The other path is Tesla's approach—'building robots like building cars.'
Tesla is far more aggressive. They're applying the same playbook from their automotive business: build the production lines first, scale up mass production from the get-go.
In their Q2 earnings release on July 23, Tesla confirmed that the former Model S/X production lines at the Fremont plant have been retired and are now being refitted for the first-generation Optimus production line, with a planned annual capacity of 1 million units and production expected to begin later this year.
A second line is also under construction at the Gigafactory Texas, with a long-term design capacity target of 10 million units per year, slated to come online in the summer of 2027.
However, it's worth noting that the first batch of Optimus units produced won't be deployed directly to factory floors. Instead, they will be fed into 'Optimus Academy'—a program dedicated to training data collection and further development.
According to Tesla's official roadmap, the early versions of Optimus do not yet have mature industrial production capabilities—there are still many areas that need refinement. The target price of $20,000 is a long-term goal; we're still far from that today.
So here's the picture: on one side, you have Chinese-made units iterating in real factory environments. On the other, Tesla is building production lines with million-unit capacity from the ground up.
We're still a long way from full-scale worker replacement—costs, generalization capabilities, joint longevity, and other bottlenecks remain. But the shift from prototypes to small-batch industrial applications? That trend is already clear.
The general industry consensus is that within the next 3 to 5 years, humanoid robots are expected to enter factories at scale, taking on tasks such as material handling, loading/unloading, sorting, and assisted assembly.
Once humanoid robots hit the factory floor, connector demand multiplies overnight.
Why is the humanoid robot such a big opportunity for connectors?
Because the sheer difference in usage volume is staggering.
By industry estimates, a traditional six-axis industrial robot typically requires only a few dozen sets of connectors per unit.
What about a humanoid robot? With dozens of moving joints across its body, a large array of force, tactile, and vision sensors, and massive power and signal transmission needs between dexterous hands, servo joints, and the main control unit—the numbers are on a completely different scale.
Industry estimates suggest that a single humanoid robot can require upwards of 100 sets of connectors—several times more than a standard industrial robot.
Take the dexterous hand, for example. A single hand typically requires more than a dozen micro-connectors to transmit tactile and force feedback signals from multiple sensors. Two hands alone account for 20 to 30 connector sets—and that's just the hands.
Add to that the power connectors and encoder connectors for each servo motor, the high-speed connectors for vision modules, and the various interfaces on the main control unit—it all adds up to a significant total.
As volume goes up, so does value.
In other words, the incremental demand that humanoid robots bring to the connector industry is a structural doubling—an upside comparable to the boom that occurred when new energy vehicles replaced traditional internal combustion engine vehicles.
And here's the kicker: the technical requirements that humanoid robots impose on connectors are far more demanding than those of consumer electronics—and in some cases, even more stringent than automotive-grade connectors.
First, high-flex dynamic durability.
Humanoid robot joints are in constant rotation and reciprocating motion. The connectors and cables must withstand millions—or even tens of millions—of flexing cycles, while maintaining stable contact resistance under continuous vibration and tension—no signal loss, no disconnection.
This requirement is far more demanding than ordinary industrial connectors, and on par with those used in automotive chassis applications.
Second, miniaturization and integration.
The internal space inside each joint is extremely limited, so connectors must be very compact. Moreover, many scenarios require hybrid power and signal transmission—one interface carrying both high-current power delivery and high-speed data communication. This places significant demands on the design.
Third, high-speed transmission and interference immunity.
With a large number of sensors and cameras transmitting data in real time, connectors need high bandwidth, low loss, and excellent electromagnetic shielding to ensure low-latency transmission of embodied AI instructions and sensory feedback.
If the robot reacts even half a beat too slowly, it could miss a grab or collide with equipment.
Fourth, industrial-grade reliability.
Factories experience wide temperature swings, high vibration levels, and exposure to oil and dust. Connectors must be built to endure long-term, continuous industrial operation—not as fragile as consumer electronics components.
As you can see, three factors converge: high unit volume, high value per unit, and high technical barriers. Together, they define the market potential for humanoid robot connectors.
In the past, the market focused more on motors, reducers, and large model algorithms—connectors were an underappreciated component. But as whole units move from the lab to factory mass production, the bottleneck effect of connectors will become increasingly evident. Demand for dedicated humanoid robot connectors is poised for rapid release.
Do domestic connector manufacturers have a shot?
There are definitely opportunities—and they are substantial.
Why? Because the competition in humanoid robots is not just about algorithms. It's a comprehensive battle encompassing supply chains, mass production iteration, and industrial application know-how.
China has the world's most complete smart manufacturing supply chain. The vast number of factories across automotive, 3C, and new energy sectors provide a natural training ground for humanoid robots, while simultaneously offering local connector suppliers a golden window of opportunity.
Global giants like TE Connectivity, Amphenol, and Molex have deep roots in high-end industrial connectors, but they suffer from slower iteration cycles and higher costs.
Domestic connector manufacturers—such as AVIC Jonhon, Luxshare, and Amass—have built considerable precision manufacturing capabilities over the years in automotive and industrial control. Their automotive-grade reliability, precision tooling, and wiring harness integration expertise can all be readily transferred to humanoid robot applications: joints, power delivery, and signal connectivity. Moreover, being closer to customers allows for faster response times, enabling them to iterate rapidly alongside local OEMs and conduct custom development and validation.
In the past, when it came to high-end industrial connectors, we were largely following the standards and roadmaps set by overseas giants. With this entirely new track of humanoid robots, we are finally standing at a starting line that is much closer to parity.
Several domestic players are already accelerating their efforts. For instance, Rui Keda (Recodeal) has launched dedicated connector products for humanoid robots, with business collaborations already underway with leading overseas OEMs, while also advancing sample validation with multiple local robot manufacturers. Other major domestic connector suppliers—including Luxshare Precision, AVIC Jonhon, and Dianlian Technology—are also investing heavily in R&D across key areas such as joint power connectors, micro board-to-board connectors, high-speed signal connectors, and integrated robot wiring harnesses.
But challenges remain.
First, the interfaces on humanoid robots are not yet fully standardized. Most current development is custom—each OEM has its own approach. Connector manufacturers have to follow the varying specifications of their customers, which requires significant upfront investment.
Second, components need long-term validation on actual robotic platforms. The certification cycles are extended—you cannot simply design a connector and sell it immediately. It has to undergo extensive real-world testing alongside the robots themselves.
Third, cost pressure will inevitably propagate upstream from the entire unit. Connector companies must strike a delicate balance among high performance, uncompromised reliability, and stringent cost control—a challenging equation.
Most importantly, the overall industry shipment volume is still in its early stages. Truly large-scale orders will only materialize after the whole units themselves reach volume production.
For now, we are still in the phase of sample validation and small-batch pilot support. We are still some distance from the full-scale realization of revenue.
A few final thoughts.
Xiaomi and Tesla—two of the industry's leading players. One is iterating inside a real factory, the other is building production lines for mass manufacturing. Together, they are pushing the humanoid robot timeline forward.
Humanoid robots won't take over the world overnight. Full-scale worker replacement tomorrow is not going to happen—costs, technology, and reliability still have a long way to go.
But over the next 3 to 5 years, large-scale deployment in factory settings is already a high-probability event.
In this process, connectors—serving as the 'blood vessels and nerves' of robots—will see growth on both volume and value fronts.
For domestic connector manufacturers, humanoid robots are not a short-term hype play. They represent another long-term growth trajectory worth building on, following the new energy vehicle boom.
Whether they can overcome the technical hurdles—high-dynamic reliability, miniaturized hybrid integration, and more—and keep pace with the iteration rhythm of the whole units, will determine who captures the upside in this wave.
