Compact, Fully Featured, and Made-in-China: Mini Industrial PC Powers the Next Generation of Inspection Robots

Inspection robots are becoming a key enabler for unmanned industrial inspection, helping factories, utilities, and critical infrastructure operators reduce labor costs and improve safety. At the heart of these robots lies the computing core, which must be compact, reliable, and highly compatible with industrial systems.

In this case study, we share how a customer in the inspection robot industry selected the SINSMART SIN-B3053-RK3588 Mini Industrial PC to overcome design challenges and achieve intelligent upgrades for their robotic platform.

I. Customer Background

The customer is a specialist in the design and manufacturing of intelligent inspection robots. These robots must support autonomous navigation, precise sensing, and intelligent analytics, which require powerful edge computing hardware. The mini industrial PC was identified as the key component to meet these requirements while fitting into the limited space of the robot’s chassis.

II. Customer Requirements

The customer defined a very clear and detailed set of technical requirements for the computing module:

• Compact Size – Overall dimensions no larger than 200 × 160 × 50 mm, enabling integration into the robot’s internal compartment.

• Domestic CPU – Must use a China-made processor, aligning with national policies for self-controllability and localization.

• Storage & Interfaces – Minimum 500 GB storage capacity, equipped with:

  • 1× Gigabit Ethernet port

  • 2× USB ports

  • 1× RS232 port

  • 2× RS485 ports

• System & Mounting – Support for Ubuntu OS, with DIN-rail mounting to ensure secure installation inside the robot.
  
  

III. SINSMART Mini Industrial PC Solution

To meet these requirements, SINSMART recommended the SIN-B3053-RK3588 Mini Industrial PC, which matched and even exceeded the customer’s expectations in multiple dimensions:

1. Compact Form Factor & Flexible Mounting

The SIN-B3053-RK3588 measures 198 × 158 × 43 mm (W × D × H), staying within the customer’s dimensional limit. It supports DIN-rail installation, making it easy to embed securely inside the robot while saving internal space—an ideal fit for compact robotic designs.

2. Domestic CPU & OS Compatibility

Powered by the RK3588 ARM-based processor (4× Cortex-A76 + 4× Cortex-A55, up to 2.4 GHz), the system delivers strong multi-core computing performance for simultaneous sensor data processing, navigation, and AI inference. It also supports Ubuntu 18.04, fully aligning with the customer’s software stack for easy deployment and stable operation.

3. Storage & Rich Interfaces

The system comes with 8 GB onboard eMMC and an M.2 slot supporting NVMe SSDs, allowing simple expansion to 500 GB or higher capacity. For connectivity, it offers:

• 2× Gigabit LAN ports

• 4× USB ports (including USB 3.0)

• 6× COM ports (jumper-configurable for RS232/RS485 combinations, meeting the requirement of 2× RS485 + 1× RS232)

• 3.5 mm combo audio interface

This not only meets but exceeds the required interface list, leaving room for future expansion.

IV. Conclusion

This project demonstrates how the SINSMART SIN-B3053-RK3588 Mini Industrial PC meets the strict requirements of inspection robots with its compact footprint, domestic CPU, rich I/O, and strong OS compatibility.

More than just a hardware platform, it provides a reliable computing backbone that enables customers to build stable, efficient, and intelligent robotic solutions. By selecting SINSMART, the customer has strengthened their product’s performance and accelerated their path toward a smarter, fully autonomous inspection ecosystem.
