170 mm çaplı tekerlekler ve 37 mm planet redüktörlü motorlar kullanacağım dört çeker (4WD) bir robot için hafif ama sağlam bir alüminyum şaseye ihtiyacım var. Hedefim yüksek manevra kabiliyeti ve hızlı hareket; bu nedenle tasarımın ağırlığı minimum tutulurken rijitliği korunmalı. Beklentilerim • Motor ve tekerlek yuvaları: 37 mm motor gövdelerine tam oturacak, kolay montajlı slotlar ve cıvata delikleri. • Şase yerleşimi: Pil yuvası, ESC/sürücü kartı ve kontrol elektroniği için korumalı, erişimi kolay bölmeler. • Dengeli ağırlık merkezi: Hızlı ivmelenmede yalpalamayı azaltacak konumlandırma. • Montaj delikleri: Sensörler ve olası üst modüller için M3/M4 vida delikleri. • Malzeme: Sadece alüminyum levha (lazer kesim için uygun kalınlık 2-3 mm). • Teslim formatı: Lazer kesime doğrudan gönderilebilecek DXF dosyaları + montaj görünümü için basit STEP veya PDF çizim. Tasarımın üretilebilirliğini göz önünde bulundurmanızı; büküm açıları, vidalama boşlukları ve minimum kerf payını hesaba katmanızı bekliyorum. İlk taslak sonrası kısa bir revizyon turu yapabiliriz. Tamamlandığında dosyaları indirip atölyeme gönderebildiğimde proje başarıyla sonuçlanmış olacak.

Hi there, We understand you are seeking a skilled designer to create a lightweight yet robust aluminium chassis for a 4WD robot, optimized for 170mm wheels and 37mm planetary geared motors. Your requirements for precise motor/wheel housings, protected compartments for electronics, balanced weight distribution, and M3/M4 mounting points, all within a 2-3mm laser-cut aluminium sheet, are well-aligned with our expertise. TRYGVE Studio specialises in product development and CAD modelling, and we have a strong portfolio in creating precise and manufacturable designs from detailed specifications. We can assist with developing the chassis design, focusing on maintaining rigidity while minimizing weight, and ensuring the design accounts for manufacturing considerations like bending angles and clearances. Our approach involves clear staged steps, from initial concepts to final technical drawings, including a review round to incorporate your feedback. We are proficient in using industry-standard tools to deliver the required DXF files for laser cutting and simple STEP or PDF drawings for assembly views. We invite you to message us to discuss the project specifics, potential timelines, and how we can best meet your design and manufacturing needs before finalising the award. https://www.freelancer.in/u/faisal8071 Regards, Ar. Faisal Saif

The key challenge here is keeping a 2–3 mm aluminum chassis rigid and lightweight while maintaining correct wheel/motor alignment and a low, stable center of gravity for fast 4WD motion. I would develop the chassis with: 1. Parametric 3D layout for the 170 mm wheels and 37 mm geared motors. 2. Reinforced sheet-metal geometry with practical bends, clearances, and fastener access. 3. Dedicated mounting zones for the battery, ESC/driver, controller, sensors, and future modules. 4. Laser-cut-ready DXF patterns with manufacturing tolerances considered. Deliverables will include DXF cutting files, a STEP model, and a PDF/assembly view, with up to 2 revision rounds included. The scope is based on the current description; additional features are quoted separately, with no physical fabrication/testing included.

Hi there, I understand that you are in need of a lightweight yet sturdy aluminum chassis for a four-wheel-drive (4WD) robot, equipped with 170mm diameter wheels and 37mm planetary geared motors. My focus will be on ensuring high maneuverability and swift movement by minimizing weight while maintaining rigidity in the design. I will ensure that the motor and wheel slots snugly fit the 37mm motor bodies with easy-to-mount slots and bolt holes. The chassis layout will feature protected compartments for the battery slot, ESC/driver board, and accessible sections for control electronics. Additionally, I will prioritize a balanced weight center to reduce yaw during rapid acceleration. I will consider the manufacturability of the design, factoring in bend angles, screw holes, and minimum kerf allowance. Following the initial draft, we can proceed with a brief revision round. Once completed, I will provide DXF files for laser cutting and simple STEP or PDF drawings for assembly views. Looking forward to collaborating with you on this project and ensuring its successful outcome. Best regards, GenZ Solutions

Merhaba, Projenizde kritik noktanın yalnızca hafif bir şase modellemek değil, 2–3 mm alüminyumdan üretildiğinde motor hizasını ve rijitliğini koruyan, lazer kesim ve büküme uygun bir yapı oluşturmak olduğunu düşünüyorum. 170 mm tekerlekler ve 37 mm planet redüktörlü motorların ölçülerine göre motor/aks yerleşimini oluşturup, hızlı hareketlerde stabilite için ağırlık merkezini mümkün olduğunca aşağıda tutacak şekilde şaseyi tasarlayabilirim. Tasarımda motor ve tekerlek hizası, montaj kolaylığı, şase rijitliği, ESP/sürücü ve batarya yerleşimi, M3/M4 modül bağlantıları, büküm açıları ve üretim toleranslarını dikkate alacağım. İlk taslağı sizinle paylaşarak geri bildiriminize göre gerekli revizyonları yaparım. Teslim: Lazer kesime hazır DXF Montaj/genel model için STEP Ölçülendirilmiş PDF teknik çizimler Amacım yalnızca görsel bir 3D model değil, doğrudan atölyeye gönderilebilecek üretilebilir bir şase tasarımı teslim etmek. Başlangıç için motor teknik çizimi/ürün linki ve elektronik-batarya ölçülerinin paylaşılması yeterlidir. İyi çalışmalar.
