Inspection Robot Controller and Vision Solution
Rail-mounted and wheeled inspection robots patrol distribution rooms, utility tunnels and plants, streaming both visible-light and thermal imagery while reading meters, recognizing equipment status and supporting remote teleoperation. Built on the RK3588 core board (4×A76 + 4×A55, 6TOPS NPU), this solution covers dual-spectrum camera input, NPU vision recognition, navigation and teleoperation links plus wide-temperature ruggedization. Delivered in modules with prototype integration and pilot support — send us your duty scenario and get selection advice within 48 hours.
Pain Points
- Synchronizing visible-light and thermal streams is tricky, and image registration takes significant effort
- Meters vary widely in type and dial style, making reading algorithms hard to generalize
- One controller must run navigation, recognition and teleoperation at once, so compute and power are hard to balance
- Distribution rooms and tunnels bring wide temperature and humidity swings plus dust, causing board instability
- Interface needs are scattered, requiring reserved Ethernet, serial, CAN and gimbal control ports

FAQ
Q：Why choose RK3588 for an inspection robot controller, and when is RK3576 enough?
Inspection robots typically run dual-spectrum video, vision recognition, navigation and teleoperation together, a multi-task load that RK3588 (4×A76 + 4×A55, 6TOPS NPU) handles more comfortably in parallel. If the robot only does single-spectrum recognition with few channels and is cost or power sensitive, RK3576 (4×A72 + 4×A53, 6TOPS NPU) can be evaluated.

Q：What accuracy can meter reading recognition reach?
Accuracy depends on meter type, camera angle and lighting, and varies significantly between analog gauges and digital meters. We improve results through on-site sample collection, per-point training and periodic sample feedback iteration, and mark low-confidence results for manual review instead of trusting them directly. We recommend acceptance testing in the target scene and defining acceptance criteria from measured data.
Q：Can our existing navigation module and chassis connect directly?
Yes. The controller provides Gigabit Ethernet, multiple serial ports and CAN, and your navigation module and chassis connect using their existing protocols; we handle interface adaptation plus teleoperation link and video return integration. For proprietary protocols, sharing the protocol document is enough to assess the adaptation approach.
Q：How is controller reliability ensured in harsh distribution rooms and tunnels?
The hardware uses wide-temperature components, fanless cooling and reinforced connectors to reduce dust and vibration failures, while software provides watchdogs, automatic recovery and power-loss protection. The actual operating temperature range and ingress protection depend on the final structure and measured results; high-temperature, high-humidity and long-duration run tests can be arranged during the prototype stage.
