I’m building a compact, four-legged robot and need a mechanical designer who can take it from concept to validated CAD. Whether you prefer SolidWorks or Fusion 360 is completely up to you—the important part is a solid background in robotics mechanisms, joints, linkages, and gears, backed by a portfolio that shows assemblies in motion rather than static renders. Project scope The core task is a lightweight yet strong leg architecture. Each leg will have hip and knee joints that must offer a wide range of motion and allow precise control once the actuators and gearing are in place. Please reserve internal volume and mounting points for a Jetson board alongside a battery pack, and route cabling logically so the final build stays neat. What I expect from you • A full 3D assembly of the four-leg structure, complete with motor, gearbox, and bearing selections. • Motion-simulation files proving joint travel, clash-free movement, and expected torque requirements. • Drawings (DXF/PDF) and STEP/STL exports ready for machining or printing. • A concise BOM with part numbers and material notes that balance weight against durability. Acceptance criteria 1. CAD shows continuous hip and knee rotation to the specified angles without interference. 2. Finite element or equivalent strength verification demonstrates load capacity meets targets while staying under the weight limit we’ll define together. 3. All electronics and batteries fit within the allocated envelope with clearance for heat dissipation. If you thrive on precision mechanisms and can iterate quickly, let’s talk details and timelines.

Hello, We are Vutuk Design and Media, a multidisciplinary engineering team specializing in robotic mechanism design, parametric CAD, and design for additive manufacturing. Your quadruped robot project requires a strong balance between mechanical realism, motion accuracy, and manufacturability—which is exactly where our expertise lies. We design complex robotic systems with precise joint kinematics, servo compatibility, and optimized tolerances for FDM printing (PLA/PETG). Our workflow ensures seamless transition from CAD to simulation (CoppeliaSim) and physical prototyping . We will deliver a fully parametric CAD package (Fusion 360/SolidWorks compatible), including assemblies, STEP/STL files, and a modular design for easy fabrication and testing. To ensure the best outcome, we would like to clarify: What are the motion requirements (walking speed, stability focus)? Do you have preferred actuator specifications or constraints? What level of anatomical detail is expected in the robotic hand? Should the design allow future upgrades or modular attachments? We would be glad to support your project from concept to working prototype. Please visit our profile to explore our portfolio and capabilities. Looking forward to working together.

I’ve worked on mechanical assemblies involving articulated linkages and motion systems where precision, weight optimization, and reliable movement are critical. Your requirement of developing a four-legged robot with efficient hip and knee joints, proper actuator integration, and clean internal layout is clear. I can design a lightweight yet strong leg architecture with well-defined joints, bearing support, and space allocation for motors, Jetson board, and battery, ensuring clean cable routing and serviceability. I’ll also validate the design through motion studies and basic strength checks to ensure smooth, clash-free movement and realistic load handling before prototyping. The focus will be on creating a practical, modular assembly that balances strength, weight, and manufacturability while staying adaptable for future iterations. Would you like the initial design to prioritize maximum range of motion or higher load capacity and stability? Mayank

With a broad background in mechanical design, engineering, and an expert command over Solidworks, I am confident in delivering precisely what you need for your quadruped robot project. My experience doesn't only end at creating CAD models; it also includes analyzing their performance using tools like ANSYS. This proficiency will prove invaluable as I ensure that your robot's leg architecture is optimized for weight and strength while maintaining its functionality and range of motion. I am well-known for my attention to detail and prompt iterations. My past projects include designing complex assemblies such as machinery transmissions and elevated structures, which demanded high precision and the ability to iterate quickly, just like your project. I take immense pride in ensuring that my designs don't just look good on paper or screen but work flawlessly in real-life scenarios. Furthermore, I possess the theoretical and practical competencies necessary for this job, from choosing the right motors, gearboxes, and bearings to predictively designing for electronics placement alongside a battery pack. Lastly, in terms of meeting your deadline commitments without compromising quality or integrity, I've proven myself on high-pressure projects like designing an all-terrain vehicle (ATV) and hydraulic power vehicles (HPVC). Choose me for a thorough, sophisticated solution that exceeds expectations at every turn.
