Humanoid robots dominated the CES floor this year. From advanced perception systems to fluid, human-like movement, the latest demos made one thing clear: these machines are no longer research concepts — they are complex, integrated systems moving rapidly toward real-world deployment.
But behind every impressive demo is a set of very real engineering challenges that must be solved before humanoid robots can scale reliably and cost-effectively.
Here are three design realities highlighted by this year’s most talked-about humanoid platforms:

1. VISION SYSTEMS THAT MUST PERFORM IN CONSTANT MOTION
Many of the most advanced demos showcased sophisticated perception stacks, combining multiple cameras and sensors to enable real-time environment awareness and object recognition. These systems are typically concentrated in compact head assemblies that must move continuously and precisely.
Design challenge:
High-speed data paths must remain stable despite vibration, tight PCB stacking, and slight board misalignment caused by mechanical movement and thermal variation.
Design focus:
Engineers must balance signal integrity, connector density, and mechanical tolerance in extremely limited space — especially where multiple high-speed interfaces converge. In practice, even small mechanical shifts can disrupt performance if interconnect strategies are not designed for motion from the start.
Solution:
Floating board-to-board connectors such as the DF40F Series help absorb X-Y PCB misalignment caused by vibration and mechanical tolerance stack-up, while micro-coax interfaces like the DF81 Series support controlled-impedance routing for high-speed camera and sensor signals in compact head assemblies.
2. FULL-RANGE ARTICULATION INTRODUCES NEW RELIABILITY DEMANDS
Beyond perception, full-body motion is what differentiates humanoids from earlier robotic platforms. Several demonstrations—including robots capable of full 360-degree joint rotation—highlighted how far dynamic modern articulation has come.
Design challenge:
Power and signal connections must tolerate continuous flexing, twisting, and vibration while fitting into compact joint structures. Designs that perform well in stationary or limited-motion robots may not survive the mechanical stress of human-like articulation.
Design focus:
Interconnect strategies in articulated sections must account for long-term mechanical stress, secure mating, and controlled cable routing without sacrificing electrical performance.
Solution:
Compact wire-to-board and cable connectors with secure locking and vibration-resistant contact structures, such as FH34 Series FPC/FFC connectors and ruggedized wire-to-board interfaces, help maintain stable power and signal connections through joints where flexing and rotation are continuous.

3. SYSTEM-LEVEL INTEGRATION ACROSS THE ENTIRE BODY
As humanoid platforms mature, performance is increasingly defined by how subsystems work together rather than how they perform individually. Many platforms at CES demonstrated tightly integrated architectures coordinating vision, control, actuation, and mobility in real time.
Design challenge:
Different body zones— head, torso, arms, and lower body — each impose unique electrical and mechanical requirements, yet must operate as part of a single, synchronized system.
Design focus:
Design teams must evaluate interconnect solutions not just by individual specifications, but by how well they support consistent, scalable architectures across multiple system domains. This pushes teams to think less in terms of isolated subsystems and more in terms of platform-level design strategies.
Solution:
Using connector families that span signal, power, and hybrid interfaces—including high-speed Ethernet options like ix Industrial™ alongside board-to-board and power connectors—helps maintain consistent interconnect strategies across head, torso, and mobility subsystems.
In distributed architectures, branching solutions such as DF22B and DF51B further support modular power routing and service access across independently developed subsystems.
SYSTEM INTEGRATION IS BECOMING THE BOTTLENECK
The pace of change on the CES floor has been striking. In 2022, humanoid robots were rare and largely conceptual. By 2025, they were widespread—demonstrating that mechanical platforms, sensors, and actuation systems are advancing rapidly and at scale.
That shift suggests the next challenge is no longer building robots, but deploying them effectively.
As humanoid platforms move into real environments, system integration is likely to become the limiting factor. Software frameworks must adapt robots to specific tasks, spaces, and workflows while coordinating perception, motion, and decision-making in real time. This integration layer—rather than hardware availability—may ultimately determine how quickly humanoid systems move from pilots to production.
While software enables intelligence and adaptability, the physical system must support it. Reliable power distribution, high-speed data paths, and mechanically tolerant interconnects are essential to ensure sensors, compute modules, and actuators operate together under continuous motion and real-world stress. Robust hardware architectures do not replace software—but they reduce friction, giving integration teams a stable foundation on which software-driven systems can scale.
THINKING FORWARD
The evolution of humanoid robotics points toward a modular ecosystem, similar to mature automotive and industrial markets. Rather than a single company designing every subsystem, specialized suppliers increasingly develop compute, sensing, actuation, and control modules, while platform developers focus on mechanical integration and system architecture.
In this environment, interconnect strategies must support independently developed subsystems while allowing the overall platform to evolve. Branching power and signal distribution, serviceable harness designs, and mechanically tolerant connectors become key enablers—helping system integrators assemble, adapt, and maintain complex humanoid platforms over time.
With experience supporting motion-intensive systems across automotive, industrial automation, and robotics applications, Hirose develops interconnect solutions with real-world operating conditions in mind. A broad portfolio of signal, power, hybrid, and high-speed connector families allows design teams to apply consistent approaches across subsystems—simplifying integration today while supporting platform evolution over time.

CONCLUSION
From Impressive Demos to Deployable Systems
CES made it clear that humanoid robotics is advancing quickly — but reliable system design will ultimately determine how rapidly these platforms reach real-world deployment.
Translating demonstration platforms into manufacturable products requires careful attention to system architecture, including how power and data move throughout the machine under continuous motion and mechanical stress.
Understanding these system-level challenges early can help teams make design decisions that scale from prototype to production.
