CHARPIE reserves the right to determine whether a product qualifies for warranty service after inspection.
Underwater ROV Frequently Asked Questions (FAQ)
🔧 Product & Technical Questions
🧭 Navigation & Software
What's the maximum depth your ROVs can operate?
Our ROVs are pressure-tested and rated for depths up to 300 meters. Always check the product specifications before diving.Does the ROV support live video streaming?
Absolutely. Each unit supports real-time video transmission to your control computer. You can view live footage via QGroundControl, VLC, or our custom app.How long can the ROV operate on a single charge?
The 220VAC Powered ROV has unlimited underwater operation hours. For the Li-ion battery powered ROVs, the battery endurance depends on the model and usage. Typically, 2–4 hours of continuous operation under normal conditions.What is the control range?
With a tether connection, you can operate the ROV up to the length of the cable (typically 100–300 meters). Wireless control is available for surface or shallow-water testing only.Is it possible to upgrade the thrusters or add sensors?
Yes. Our ROVs use a modular design, allowing easy upgrades such as DVLs, sonars, USBL systems, lights, and HD cameras.What software is used to control the ROV?
Our ROVs are fully compatible with QGroundControl and ArduSub firmware, offering precise control, telemetry data, and mission planning features.Can the ROV hold depth or position automatically?
Yes. The ROV includes barometric depth hold and stabilized flight features. For advanced station keeping, you can integrate GPS (for surface use) or DVL/USBL for underwater positioning.Is real-time object detection or AI vision supported?
Yes. You can enable OpenCV-based real-time object detection and video overlay when connected to a companion computer (e.g. Raspberry Pi or NVIDIA Jetson).
Orders, Shipping & Warranty
Orders, Shipping & Warranty💡 Usage & Maintenance
Where do you ship from and how long is delivery?
We ship globally from our Shanghai (China) warehouse. Typical delivery times:- Asia: 3–5 days
- Europe / North America: 7–10 days
- Other regions: 10–15 days
Do you provide a warranty?
Yes. All products come with a 6-month limited warranty covering non-human-damage failures. For more details, see our Warranty Policy.Can I request a custom configuration or bulk order?
Of course! We accept custom builds and OEM/ODM requests. Please contact us via the Contact Form or email sales@charpierov.com.What payment methods are accepted?
We prefer international bank transfers (T/T) but also accept PayPal or Alipay. All transactions are securely processed.How should I maintain the ROV after use?
After every dive, rinse the ROV and tether with fresh water, check all seals, and inspect O-rings for debris. Regular maintenance ensures long-term reliability.Can I operate the ROV in salt water?
Yes. All units are designed for saltwater operation, but rinsing with fresh water afterward is essential to prevent corrosion.Is any training required?
Our ROVs are designed for both professionals and beginners. You'll receive a quick-start guide and optional online training video after purchase.Selecting the right power system is a critical design decision for underwater robots. Key factors include mission duration, operational range, and payload power needs. While tethered systems provide the stable, high-capacity energy required for industrial tools and long surveys, untethered battery-powered systems offer superior maneuverability and safety in complex environments prone to cable entanglement. By balancing these technical requirements against budget and operational costs, operators can determine the most efficient power configuration for their specific subsea missions.
