MARINOVA | 2-Motor Omnidirectional Underwater ROV | Thrust Vectoring Prototype | HYDRONE v2.2

MARINOVA is the v2.2 prototype of the HYDRONE underwater ROV platform, developed as a Mechanical Engineering capstone project.

This system demonstrates a low-cost omnidirectional underwater robot capable of multi-directional motion using only two BLDC thrusters with servo-based thrust vectoring.

Instead of conventional multi-thruster ROV designs, MARINOVA redirects thrust using high-torque servos, allowing forward motion, vertical diving, and directional maneuvering with a simplified propulsion architecture.

Key innovations of this prototype include:

• Servo-based thrust vectoring propulsion
• Omnidirectional motion using only 2 BLDC motors
• Custom 4-relay polarity switching system acting as a 4PDT switch for reverse control
• Surface buoy communication architecture to overcome underwater RF signal loss
• Fishing camera integration for underwater live view
• 3m CAT-7 Ethernet tether (8-core) for power and signal transmission

The system is divided into two main units:

Buoy Unit (Surface) – contains the receiver and communication relay
ROV Unit (Underwater) – contains motors, servos, ESCs, and power electronics

This architecture allows stable control while the ROV operates underwater.

Platform: HYDRONE v2.2
Prototype Name: MARINOVA
