When Xiaomi CyberDog 2 nails a backflip and Unitree Go2 navigates autonomously while dodging obstacles, many marvel at their precise motion control and intelligent decision-making capabilities.Yet few notice the core foundation that underpins these complex maneuvers: connectors.Serving as the "bridges" for data transmission and power supply across all modules of a robotic dog, the technological evolution of connectors is deeply intertwined with the development of robotic dogs.From lab prototypes to commercialization, the two have forged a tight bond characterized by "innovation driven by demand, and demand enabled by innovation".
Technical Architecture: The "Neural Synapses" of Robotic Dogs
The hardware architecture of a robotic dog follows a three-layer logic of Perception, Decision-Making, and Execution, and connectors are precisely the key nodes that link these three layers together.A standard quadruped robot is equipped with 12 joint motors, paired with dozens of sensors including an IMU (Inertial Measurement Unit), LiDAR, and cameras—all these modules rely on connectors to achieve real-time data interaction and power transmission.
At the core control layer, the main controller and sub-controllers work in synergy via connectors, whose transmission rate directly affects the latency of command responses. Millisecond-level signal transmission ensures the precise synchronization of joint movements. High-definition cameras in the perception layer rely on connectors to achieve high-quality image transmission, while sensors output high-frequency posture data through these components. It can be said that the stability of connectors directly determines the response speed and motion accuracy of a robotic dog.
Scenario Adaptation: Technical Challenges in Different Working Conditions
As robotic dogs expand their applications into complex scenarios, differentiated requirements are imposed on connectors in terms of environmental adaptability, miniaturization and protection class—driving continuous innovation in connector technology. The LIFTF series connectors launched by Amass are precisely tailored to the operating conditions of quadruped robots, providing reliable connection guarantees for their dynamic operations.
1、In consumer-grade scenarios, robotic dogs focus on companionship and educational functions, where connectors are required to balance miniaturization and cost-effectiveness. In contrast, for industrial inspection scenarios, robotic dogs need to operate continuously in dusty, heavy rain, high and low temperature environments—thus demanding connectors with a protection class of IP67 or higher. The LIFTF series connectors adopt a dual rubber sealing ring design, which can withstand heavy rain intrusion, and their temperature resistance range of -40℃ to 120℃ enables adaptation to extreme climates.
2、Outdoor scenarios demand higher reliability, where robotic dogs must prevent connection loosening under operating conditions such as off-roading and impact. The LIFTF series connectors adopt a push-type buckle design, enabling convenient "one-plug-and-lock" connection. Combined with a push-type slot unlocking mechanism, they not only ensure connection stability in wide-frequency vibration environments but also greatly simplify the plugging and unplugging process for subsequent maintenance, thus significantly reducing the failure rate of robotic dogs caused by loose connections.
3、It adopts an automotive-grade crown spring contact structure, with the number of slotted contacts on the main rod increased from 4 to 12—boosting the contact area by 3 times. Combined with high-conductivity copper conductors, it not only meets the rated current requirements but also minimizes power transmission loss. For quadruped robots equipped with LIFTF series connectors, their stable connection performance ensures the precision of gait control, enabling smoother power transmission for the robots during complex movements such as walking and jumping on rough terrain.
Industry Development: Localization of Connectors Drives Cost Reduction and Volume Production of Robotic Dogs
As robotic dogs advance toward lightweight and intelligent upgrades, connectors will evolve in the direction of smaller size, higher transmission rates, and stronger protection capabilities. In the future, this "invisible bridge" will continue to play a pivotal role, enabling robotic dogs to unlock value in more scenarios.
