BackDepth hold test at 3m Monitoring real-time telemetry poolside
Testing·August 20, 2025
Pool Test Session: March 2025
First in-water test of the new vehicle. Validated basic thruster control, depth hold, and leak-free operation at 3 meters.
Vehicle submerged during depth hold test at 3 meters
Test Objectives
- Validate waterproof integrity of new hull
- Test basic thruster control (forward, reverse, yaw)
- Achieve stable depth hold at 2-3 meters
- Check sensor readings underwater
Team members monitoring telemetry during pool test
Results
| Test | Status | Notes |
| Leak test (30 min) | Pass | No moisture detected in any compartment |
| Forward/reverse | Pass | Smooth acceleration, good response |
| Yaw control | Pass | 360-degree rotation in < 5 seconds |
| Depth hold | Partial | Oscillation at 3m, PID needs tuning |
| Sensor check | Pass | All sensors reporting accurate data |
Key Takeaways
- Hull integrity is excellent
- Depth hold PID parameters need adjustment
- Thruster response time is within spec
- Camera housing performed well underwater
