ROV Control Algorithm for Blue Robotics
Budget: $1,500 – $3,000 USD
Development of Advanced ROV Control Algorithm for Inverted and 90-Degree Stability
Project Description:
We are seeking an experienced engineer or team to develop a custom control algorithm for an advanced underwater ROV based on the Blue Robotics Heavy Configuration platform. The primary focus of this project is enabling the ROV to perform inverted dives, maintain 90-degree orientations, and sustain depth, heading, and attitude stability under dynamic underwater conditions.
This system must seamlessly integrate with the existing Blue Robotics ecosystem and operate reliably with our custom ROV design, which is double the weight and wider than the standard BlueROV2 Heavy Configuration. The solution should also support manual joystick-based control and allow for predefined autonomous mission routes.
Project Goals:
1. Inverted Operation:
• Enable the ROV to dive inverted and hold a stable orientation regardless of external forces.
• Maintain control of depth, heading, and attitude simultaneously during inverted operations.
2. 90-Degree Orientation Stability:
• Develop the ability to hold and dynamically adjust to specific angles (e.g., 90°, -90°, or user-defined).
• Ensure smooth transitions between orientations.
3. Depth and Heading Control:
• Ensure precise depth stabilization using the Bar30 depth sensor.
• Maintain accurate heading control to compensate for currents or external forces.
4. Manual Joystick Integration:
• Allow for full manual control of the ROV, including dynamic attitude adjustments.
• Ensure intuitive joystick-based control for all movements and angles.
5. Automated Mission Routes:
• Provide functionality for creating and executing waypoint-based mission routes.
• Allow dynamic orientation adjustments at specific waypoints during autonomous missions.
Key Deliverables:
1. Custom Control Algorithm:
• Develop and implement a stabilization algorithm for inverted dives and 90-degree holds.
• Integrate control for depth, heading, and attitude maintenance under varying external forces.
2. Firmware Updates:
• Modify the ArduSub firmware to support custom control requirements while maintaining compatibility with BlueRobotics hardware.
3. Joystick Integration:
• Configure a joystick controller for manual operation, including real-time adjustment of pitch, yaw, and roll angles.
4. Mission Planning and Execution:
• Enable configuration of autonomous routes using waypoints.
• Integrate features for dynamic attitude adjustments at each waypoint.
5. Testing and Validation:
• Simulate and test the system in software (e.g., Gazebo or ArduSub SITL).
• Verify functionality in real-world underwater environments, ensuring stability, responsiveness, and accuracy.
Technical Specifications:
• Hardware:
• Pixhawk with ArduSub firmware (latest version).
• Raspberry Pi for peripheral management.
• 8 Blue Robotics thrusters in a heavy-duty configuration.
• Bar30 pressure sensor for depth control.
• Software:
• Modify ArduSub firmware for advanced stabilization.
• Use pymavlink, MAVSDK, or ROS for custom scripting and real-time control adjustments.
Required Expertise:
1. ROV Control Systems:
• Proficiency in developing control algorithms for stabilization (pitch, yaw, roll).
• Experience with PID tuning for underwater robotics.
2. ArduSub Firmware Development:
• Strong understanding of ArduSub, MAVLink, and Blue Robotics hardware.
3. Programming and Algorithm Design:
• Proficiency in Python and C++ for control systems and dynamic parameter adjustments.
4. Simulation and Testing:
• Experience with underwater robotics simulators (e.g., Gazebo or SITL) for testing and validation.
5. Hardware Integration:
• Familiarity with joystick controllers and peripheral integration using Raspberry Pi.
What We Provide:
• Detailed ROV design specifications, including dimensions, weight distribution, and thruster configurations.
• Access to all necessary hardware components (Pixhawk, Raspberry Pi, thrusters, etc.).
• Documentation and technical support for existing systems.
Budget and Timeline:
• Budget: To be discussed based on complexity and scope.
• Timeline: Flexible, with milestones for development, testing, and final delivery.
How to Apply:
Please submit:
1. A summary of your experience with underwater robotics, control systems, and ArduSub firmware development.
2. Relevant examples of previous projects, particularly involving stabilization or attitude control.
3. Your proposed approach to achieving inverted and 90-degree stabilization with depth and heading control.
This project requires innovative thinking and hands-on experience in underwater robotics. We look forward to collaborating with skilled professionals passionate about advancing ROV capabilities.
