Dear Valued Customer,

Thank you for your continued support.
In the logistics and manufacturing industries, the adoption of AGVs (Automated Guided Vehicles) and AMRs (Autonomous Mobile Robots) is accelerating to address labor shortages and improve productivity. The combined AGV and AMR market is expected to grow from USD 7.9 billion in 2025 to USD 23.0 billion by 2035 (CAGR 11.2%). 
This time, we focus on charging connector technology, one of the key factors supporting stable robot operation.

● Charging Systems: A Critical Factor for AGV and AMR Performance

As the number of deployed robots increases, there is a growing need to automate charging operations and reduce maintenance workloads. One charging method attracting significant attention is automatic charging using spring connectors (Pogo Pins), which eliminates the need for plug insertion and removal.

● Growing AGV & AMR Market and the Importance of Charging Infrastructure

Driven by the expansion of e-commerce and increasing investment in logistics automation, AGV and AMR adoption continues to grow worldwide. As the number of robots increases, reducing charging-related downtime and maintenance work becomes increasingly important. As a result, many manufacturers are adopting automatic charging systems.
 

● Three Key Requirements for AGV & AMR Charging

① Tolerance to Positional Misalignment
Since AGVs and AMRs operate autonomously, slight positioning errors can occur when docking at charging stations. Connection methods that are sensitive to misalignment may lead to charging failures or poor electrical contact. Yokowo's spring connectors utilize a spring mechanism that helps maintain stable contact while absorbing positional deviations, enabling reliable charging connections.

② Durability for Repeated Charging Cycles
AGVs and AMRs typically charge multiple times each day. Therefore, charging contacts must provide long-term durability while maintaining stable performance over repeated charging cycles. Because spring connectors are designed for frequent contact engagement, they are highly compatible with automatic charging applications.

③ Stable Charging Connections
In automatic charging systems for AGVs and AMRs, reliable charging initiation is essential every time the robot docks. If contact becomes unstable due to contamination, vibration, or slight positional misalignment, charging errors or operational downtime may occur. The spring mechanism of spring connectors helps maintain stable contact and contributes to the high level of connection reliability required in automatic charging systems.
 
<Comparison of Charging Methods>
Wireless charging offers excellent tolerance to positional misalignment, but efficiency and cost can sometimes be challenging.
In contrast, Yokowo's spring connectors make it easier to achieve both high-efficiency power transmission and automatic charging, which is why they are increasingly being adopted in AGV and AMR applications.
