I need an engineer to produce a design-only blueprint and bill of materials for a small, remotely controlled rover that moves inside a tank of mineral oil. My team will build it. The challenge: it must move in oil without creating bubbles or disturbing the oil. That means no exposed propellers, and no air or other fluid entering the oil. Buoyancy alone only moves it up and down, so I want your recommendation for controlled sideways movement and position holding. My idea is about 6 enclosed, ducted thrusters on a rounded hull, but I'm open to better. Targets (confirm or challenge with calculations): Size: 20 × 20 × 23 cm maximum Mass: 3.0 kg or less including payload (bare rover 2.2 kg, about 0.6 kg reserved for future sensors) Oil: 5–40 cSt, 5–70°C; rated for 3 bar absolute Battery preferred; wireless preferred, but assess feasibility inside a steel tank E-stop and float-up recovery; 60 minutes continuous run Build BOM ceiling: ₹6,50,000 Deliverables: concept and calculations, 3D CAD and drawings, electrical design, costed BOM, test plan. Terms: 3–4 weeks, fixed price paid by milestone, full IP transfer, NDA before detailed specs. Please answer in your proposal: How will your design move laterally without exposed propellers, bubbles or foreign fluid in the oil? How would you size thrust in 5–40 cSt oil? Show one similar project. Your hour estimate and start date?

At MHTechFusion, we understand that your project for a mineral oil tank rover is far from ordinary. This is precisely why our multidisciplinary engineering team is best-suited for your unique design challenge. We have extensive experience in designing products that function flawlessly in demanding and complex environments, and your project aligns directly with our core capabilities. Regarding the critical issue of lateral movement without using exposed propellers or introducing foreign fluid to the oil, rest assured we can provide a cutting-edge solution. Our idea of incorporating six enclosed, ducted thrusters on a rounded hull is an innovative approach to address this specific requirement. However, we remain committed to exploring any better alternatives that may arise during the project. Our team has already undertaken similar challenging projects which gives us added confidence in tackling yours successfully. Apart from our strong skill set in 3D CAD modeling, mechanical engineering, and product design which are crucial for executing your project, our knowledge of fludics and sealed environment management would be immensely helpful for devising a precise thrust sizing strategy aligned with the viscosity of the oil used in the tank.

Hello, I’m a Mechanical Engineer with 5+ years of experience in robotics, motorized mechanisms, embedded electronics, CAD and prototype development. I can handle the complete design package from concept and calculations through CAD, electrical architecture, BOM and test planning. Lateral movement: I would investigate fully sealed, oil-compatible ducted pump/impeller modules rather than exposed propellers. The thrusters would recirculate the surrounding oil internally, with no air intake or external fluid injection. Depending on the required maneuverability, I would consider 4–6 vectored/independently controlled modules for lateral translation, yaw and position holding. Thrust sizing: I would calculate required thrust from mass, buoyancy, drag, acceleration and control margin, then size the impeller/duct and motor using the worst-case oil viscosity (40 cSt) and temperature condition. Testing would validate the calculated thrust across the 5–40 cSt range. I would also address: - Neutral/slightly positive buoyancy and float-up recovery - Fully sealed motor/electronics compartments - 3 bar absolute pressure requirement - 60-minute battery/thermal budget - E-stop and fail-safe recovery - Wireless feasibility inside a steel tank - CAD, manufacturing drawings, electrical design and costed BOM Best regards,

As a seasoned mechanical engineer with vast experience in 3D CAD and Mechanical Engineering, I am confident that I am the perfect fit for your Mineral Oil Tank Rover Design project. My expertise in product design, particularly in creating remote-controlled systems, can be instrumental in developing an innovative rover that navigates through mineral oil without causing disturbances. I have a strong instinct for assessing the feasibility of complex designs like this and proposing rational solutions. One of my similar projects that you will find intriguing is an underwater drone that uses innovative technologies to ensure no bubbles or other fluids enter the water during its operation. I tackled maneuverability challenges by incorporating alternative propulsion mechanisms similar to what your project warrants. The lessons and skills I acquired during this process will prove critical in navigating and accurately sizing thrust in the given 5-40 cSt oil range. Looking forward to bringing your vision to life, empowering you with a detailed blue-print and bill of materials for realization by your team. Do not hesitate to reach out with any further queries; happy to address them!

As a 3D CAD engineer with extensive experience in product design and engineering, I am confident in my abilities to craft a solution that addresses your unique and challenging mineral oil tank rover project. In your quest for lateral movement without using exposed propellers or creating any disturbance to the oil, I have two cogent propositions. Firstly, we can employ the utilization of hydraulic thrusters which will enable precise controlled lateral movement all without any air or foreign fluids entering the oil medium. Secondly, I can integrate an advanced magnetic levitation system to ensure controlled positioning of the rover in the tank. Thruster sizing in 5-40 cSt oil won't be an issue since I've successfully executed numerous projects requiring exact specifications. A similar project that confers to yours is when I designed a robotic submarine to maneuver through delicate aquatic ecosystems without causing any damage or disruption. Considering the complexity and precision required for this task, I estimate it will take approximately three weeks to complete. But rest assured, I will constantly communicate with your team whilst providing timely milestones so as to ensure our progress is in line with your expectations. Let us begin this exciting venture together as soon as you are ready. Looking forward to discussing further details with you soon!

We would be happy to develop the complete design-only engineering package for your mineral-oil rover. We have extensive experience in SolidWorks, robotics, automation machines, electromechanical systems, sealed enclosures, motor/actuator selection, embedded electronics, DFM, and functional prototype development. For lateral movement, we would avoid any system that introduces external air or working fluid and evaluate fully submerged, sealed electric propulsion—most likely enclosed/guarded oil-compatible thruster modules with the rotor/impeller isolated appropriately from the electronics and arranged for multi-axis translation and position holding. The deliverables can include concept comparison, complete parametric SolidWorks CAD, manufacturing drawings, electrical architecture, motor/driver/battery selection, sealed connector strategy, E-stop and positive-buoyancy recovery concept, costed BOM within the ₹6.5 lakh target where technically achievable, and a structured test plan covering oil compatibility, pressure, thermal operation, endurance, thrust, failed propulsion, and recovery. We have worked on robotics and automation systems involving motors, sensors, embedded control, sealed/mechanical assemblies, and custom prototype hardware; relevant examples can be shared privately under NDA rather than claiming a directly identical mineral-oil rover.

I will develop a hermetic design with fully enclosed impellers in the channels for no-trace movement in oil. I will calculate the hydrodynamics for 5-40 cSt, taking into account viscous losses and the necessary thrust for position holding. From my experience: I have designed industrial tooling with motorization and feedback, including calculations for mechanical systems. How will you ensure the hermeticity of the electronics compartment at 3 bar and the heat dissipation of the components?
