Project Overview

AXION ES is developing an internal controller system for a remote-controlled life rescue boat / rescue buoy platform for professional water rescue applications. The system is being developed with a focus on reliable propulsion control, waterproof electronics, battery management, safety logic, field testing, and future upgrade capability.

This type of rescue device is designed to quickly move through water and reach a person in distress. It can help rescue teams provide flotation support and guidance from a safer distance, especially in rivers, lakes, coastal areas, flood situations, and emergency rescue operations.

The project is planned for a Bangladesh Navy-related rescue application, where reliability, durability, control accuracy, and real-world field performance are very important.

AXION ES is responsible for developing the internal control system and engineering integration support, including electrical integration, controller setup, propulsion control, waterproofing strategy, and testing support.


Project Objective

The main objective of this project is to develop a functional prototype of a remote-controlled rescue boat with a reliable internal controller system.

The controller system will be designed to manage:

  • Motor and propulsion control
  • Battery power distribution
  • Remote command reception
  • Steering and speed control
  • Safety and fail-safe logic
  • Waterproof electrical integration
  • VESC parameter setup
  • Cooling loop integration
  • Pool testing and field trial support
  • Future upgrade readiness

The target is to prepare a prototype-ready system through a structured design, procurement, fabrication, electrical integration, testing, and field validation process.


Problem Statement

In water rescue operations, time and safety are critical. Conventional rescue methods may require a rescuer, boat, rope, or direct physical entry into the water. In difficult conditions such as current, distance, floodwater, poor visibility, or unsafe surroundings, direct rescue can become risky.

A remote-controlled rescue boat can reduce risk by allowing operators to send a floating rescue platform toward the victim from a safer location.

However, to make the system reliable for professional use, the internal controller must be carefully designed. Common technical challenges include:

  • Waterproofing of internal electronics
  • Reliable motor control under load
  • Stable battery power management
  • Proper wiring and sealing
  • Motor driver and VESC setup
  • Signal loss safety response
  • Emergency stop function
  • Steering calibration
  • Runtime and thrust validation
  • Cooling and heat management
  • Field serviceability
  • Durability in real water conditions

Without a properly engineered internal controller system, a rescue platform may fail during operation, lose communication, suffer electrical damage, or perform inconsistently in water.


AXION ES Recommended Solution

AXION ES is developing a custom internal controller system that can be integrated into the life rescue boat hull. The system will control propulsion motors, manage battery power, receive remote operator commands, and support safe operation during rescue use.

The proposed solution includes:

  • CAD-supported controller and mounting layout
  • Hull, ducting, mounting, and sealing design support
  • Motor and ESC integration
  • Battery and radio system integration
  • Waterproof wiring and connector planning
  • VESC parameter setup
  • Internal cooling loop arrangement
  • Safety testing
  • Pool testing
  • River field trial support
  • Performance data reporting

The goal is to create a prototype that is practical, serviceable, and suitable for further field development.


Proposed Work Plan

The project will follow a structured multi-phase development plan. This phased approach will help reduce technical risk and allow the team to validate each major part of the system before final field trials.


Phase-wise Development Details

Phase 1 – Design Finalization

In the first phase, the mechanical design will be finalized. This includes CAD modeling of the hull, ducting, internal mounting position, controller placement, and sealing approach.

This phase is important because the electronic controller, battery, motor wiring, ducted propulsion system, and waterproofing strategy must be planned before fabrication and integration.

Key focus areas:

  • Hull layout review
  • Ducting design
  • Internal mounting position
  • Sealing design
  • Maintenance access planning
  • Controller and battery placement
  • Space planning for wiring and cooling

Phase 2 – Procurement and Fabrication

After design finalization, the required parts will be sourced and fabricated. This includes motors, ESCs, batteries, radio communication components, and required mounting hardware.

This stage also includes fabrication of motor mounts and internal support structure so that the control system can be installed securely inside the rescue boat.

Key focus areas:

  • Motor sourcing
  • ESC sourcing
  • Battery sourcing
  • Radio system sourcing
  • Mount fabrication
  • Mechanical fitting preparation
  • Component compatibility checking

Phase 3 – Electrical Integration

In this phase, AXION ES will perform the internal electrical integration work. This includes wiring, waterproofing, VESC parameter setup, cooling loop integration, and controller connection.

This is one of the most important phases because the rescue boat must operate safely in a wet environment. Proper cable routing, sealing, power distribution, and protection planning are essential for stable operation.

Key focus areas:

  • Internal wiring
  • Waterproof cable routing
  • Connector and sealing work
  • VESC parameter setup
  • Battery and power distribution
  • Receiver and controller connection
  • Cooling loop integration
  • System protection planning
  • Initial bench testing

Phase 4 – Pool Testing

After electrical integration, the prototype will go through controlled pool testing. This phase will validate basic movement, thrust, runtime, steering response, and safety behavior before open-water testing.

Pool testing allows the team to observe the system in a safer and more controlled environment.

Key focus areas:

  • Thrust validation
  • Runtime checking
  • Steering calibration
  • Motor response testing
  • Remote control response
  • Emergency stop testing
  • Waterproofing observation
  • Safety testing

Phase 5 – Field Trials and Reporting

After successful pool testing, the system will be tested in river or real-water rescue trial conditions. This phase will help validate actual field performance and collect operational data.

A final report will be prepared based on test results, performance data, observations, and future improvement recommendations.

Key focus areas:

  • River rescue trial
  • Real water movement test
  • Operator control assessment
  • Runtime and power observation
  • Steering performance
  • Stability observation
  • Performance data collection
  • Final reporting
