Título del proyecto: Prototipo de robot submarino para recuperar pelotas de golf del fondo de lagos Descripción: Busco un ingeniero/a (mecánico, electrónico o de robótica) para diseñar y construir un prototipo funcional de un robot submarino de bajo coste, capaz de recoger pelotas de golf del fondo de lagos/estanques de campos de golf. Contexto del proyecto: Los campos de golf pagan actualmente a buceadores para recuperar pelotas del fondo de sus lagos (agua turbia, sedimento, ramas y plantas). Quiero sustituir ese trabajo manual por un robot. Es un prototipo inicial para validar la idea, no un producto industrial — presupuesto ajustado. Requisitos funcionales: Debe operar en el fondo de lagos poco profundos (indicar rango de profundidad orientativo, ej. 0,5–3 m). Debe funcionar en condiciones de barro/sedimento blando y con presencia de plantas/ramas sin quedar atascado. Mecanismo de recogida y almacenamiento de pelotas de golf (succión, garra, cinta o tolva — abierto a propuestas). Preferiblemente operado por cable (tethered) desde la orilla para simplificar la alimentación eléctrica y evitar depender de baterías; alternativamente, batería con autonomía para operar varias horas seguidas. Sistema de navegación/visibilidad básico para el operador (cámara con luz, dado que el agua suele ser turbia). Objetivo de uso: varias horas de operación continua al día. Lo que busco del freelancer: Experiencia previa en electrónica embebida, mecánica/CAD, o robótica (ROV, drones, IoT). Capacidad de proponer un diseño conceptual antes de construir (bocetos o CAD simple). Entregable: prototipo físico funcional + documentación básica (esquema eléctrico, lista de materiales, instrucciones de uso). Si es asi ponme en contacto con ellos

Hi there, I have carefully reviewed your project requirements for a low-cost underwater robot capable of recovering golf balls from shallow lakes and ponds while operating in muddy, plant-filled, low-visibility environments. My background in mechatronics, embedded electronics, robotics, PCB design, CAD, motor control, sensors, and electromechanical prototyping is well suited to this project. I have already worked with the main technologies involved, including underwater-capable electronics, DC motor control, cameras, lighting, tethered communication/power systems, mechanical collection mechanisms, and remote-operated robotic platforms. I can handle the complete prototype development, starting with the mechanical and electrical concept, followed by CAD, component selection, control electronics, collection mechanism, tether/power architecture, assembly, testing, and documentation. For a first prototype, I would prioritize a simple tethered ROV architecture with robust propulsion and a collection mechanism optimized for soft sediment and vegetation. Given my skillset, I can move quickly from concept to a practical proof-of-concept while keeping the design cost-conscious and serviceable. Send me a message with your target depth, expected lake conditions, and preferred budget range, and I can start immediately. Best regards, Samuel tshibangu

⭐⭐⭐⭐⭐ Hi, Your project is a great candidate for a practical tethered ROV prototype rather than an overly complex autonomous system. The key is designing a robot that can actually move through soft sediment, weeds and branches while reliably collecting golf balls. I can develop the concept around a low-cost, serviceable architecture covering the mechanical frame, propulsion, tethered power/control, underwater camera and lighting, and a simple collection mechanism. I would compare suction, scoop/trolley, claw and hopper concepts based on their ability to handle muddy bottoms and vegetation without becoming clogged or stuck. The initial work would include: Define operating depth, dimensions, payload and tether requirements Develop the mechanical/CAD concept and collection mechanism Design the propulsion, control and camera/lighting system Build and integrate the physical prototype Test in realistic underwater conditions and refine the design Deliver schematic, BOM, basic CAD/design documentation and operating instructions I’m interested in building and testing the actual prototype, not just producing a theoretical design. Please share your target budget, preferred collection approach if you have one, and any available information about the typical lake depth and bottom conditions. I can then propose a practical prototype architecture and milestone plan.

Hola, soy ingeniero de sistemas embebidos con más de 16 años de experiencia en robótica, electrónica, firmware y desarrollo de productos desde el concepto hasta prototipos funcionales. Puedo abordar este ROV de bajo coste combinando un diseño mecánico resistente al barro y la vegetación con propulsión protegida, control por cable, cámara iluminada y un sistema sencillo de recogida y almacenamiento de pelotas. Primero definiré la arquitectura y prepararé bocetos/CAD, esquema eléctrico y lista de materiales para validar contigo costes y disponibilidad. Después realizaré el montaje, programación y pruebas del prototipo, documentando su operación. Para agua turbia estudiaría una recogida guiada por contacto —por ejemplo, rodillo o tolva— en lugar de depender únicamente de la cámara. También puedo apoyar futuras mejoras para convertirlo en un producto fabricable. ¿El presupuesto incluye componentes, fabricación y envío a España? ¿Dispones de un lugar donde hacer las pruebas en agua? El importe indicado corresponde a ingeniería y construcción inicial; los materiales especiales o envíos se acordarían tras aprobar el diseño. Por favor, contacta conmigo para discutir los detalles.

Hello, recuperar pelotas de golf del fondo de lagos realmente se trata de diseñar un ROV de bajo coste que no se atasque en sedimento, ramas ni plantas. I work regularly with Robotics, Prototyping, Embedded Systems, which fits closely with what you’re trying to accomplish. I’d start by reviewing the operating depth, la tolva/mecanismo de recogida y la alimentación por cable, then handle el diseño mecánico y la integración electrónica en una forma estructurada, testing la navegación, la cámara con luz y el comportamiento en agua turbia as I go rather than leaving validation until the end. The goal would be to deliver un prototipo funcional con documentación básica that is robust and simple to operar. I can begin de forma inmediata and should have this completed within 3 semanas. One thing I’d like to confirm before starting: ¿prefieres priorizar succión, garra o cinta para la captación, y cuál sería la profundidad objetivo real ¿prefieres priorizar succión, garra o cinta para la captación, y cuál sería la profundidad objetivo real??

The job specifies operating at the bottom of shallow lakes, 0.5 to 3 meters deep. I will build the prototype using an Arduino Mega for control, managing a small DC motor for thrusters, also a waterproof servo for the grabber arm, and a miniature camera for visual feedback. The housing will be a watertight ABS enclosure, sealed with O-rings, large enough for all components and ballast. I'll use a simple two-finger claw mechanism actuated by the servo, designed to grip a golf ball. The main failure point here is water ingress damaging the electronics. I'll test the enclosure integrity thoroughly before integrating the electronics. What is the desired battery life for a single retrieval mission? 5.0 rating across 10 reviews on here, and Preferred Freelancer status. I need the budget range for materials before I can provide a timeline.

GIVE ME 30 SECONDS TO SHOW YOU WHY I'M THE RIGHT FIT FOR THIS PROJECT. I recently completed a project designing a remotely operated underwater vehicle (ROV) for environmental monitoring, which successfully navigated and collected samples in murky waters. This prototype was not only functional but also met tight budget constraints. With over five years of experience in robotics and embedded electronics, I specialize in creating low-cost solutions that work effectively in challenging environments. My strong background in CAD design and prototyping aligns perfectly with your project's needs. I understand your goal is to automate the recovery of golf balls from lake bottoms efficiently. I propose a tethered design with a simple collection mechanism to ensure reliable operation in soft sediment. My focus will be on clear communication, timely updates, and ensuring the prototype's long-term success in real-world conditions. I'm excited about the potential impact of this project. The difference between an average result and an exceptional one is usually decided before the work even begins. Regards Patrick

Hola, he revisado tus requisitos y el reto principal es crear un ROV económico que pueda desplazarse y recoger pelotas en barro, plantas y agua turbia sin atascarse. Empezaría por un diseño conceptual centrado en flotabilidad, tracción, protección y un mecanismo de recogida sencillo, preferiblemente con alimentación y control por cable. Después validaría cámara, iluminación, motores y recogida en un prototipo antes de cerrar la documentación y lista de materiales. Preguntas rápidas: Q1. ¿Tienes un rango máximo de dimensiones y peso para poder transportar el robot fácilmente desde la orilla? Q2. ¿La prioridad es recoger la mayor cantidad de pelotas posible por ciclo, o conseguir primero buena movilidad y posicionamiento en el fondo? Estas respuestas ayudan a definir la mecánica y el mecanismo de recogida del primer prototipo. Puedo llevar el diseño desde el concepto hasta un prototipo funcional y documentado. Fernando García
