PALADIN – Print-in-Place Autonomous Loader And Deployable Integrated Navigator

Overview

PALADIN is a fully print-in-place, compact, multi-functional articulated robot engineered for tactical storage, mobility, and interactive functionality. Designed with bendable leg joints, a rotating thigh joint, and a unique fold-and-lock mechanism, PALADIN seamlessly combines playability with practical micro-storage.

Key Features

• Print-in-Place Articulation – All joints, including bending knees and rotating thighs, are pre-assembled during printing, requiring no additional assembly.
• Slide-Out Storage – A hidden compartment secures an SD card or small payload, utilizing a snap-fit ball socket to stay securely in place.
• Locking Mechanism – The legs fold neatly, locking PALADIN into a compact 30x30x30mm form factor, ensuring portability and structural integrity.
• Functional Catapult – Integrated into the design, the deployable catapult uses a rubber band for interactive engagement.
• Interlocking Dovetail Slots – PALADIN units can connect side-by-side, enabling modular expansion with multiple units.
• Optimized for FDM Printing – Designed with precise tolerances to ensure seamless printing on consumer-grade 3D printers without requiring support structures or post-processing.

Why PALADIN Stands Out

PALADIN redefines print-in-place mechanics, balancing utility, creativity, and modularity. It functions as an interactive toy, a functional storage unit, and a deployable scout, making it more than just a single bot—it’s an expandable, modular system. Whether used alone or linked with additional PALADINs, it fosters creative problem-solving and engineering ingenuity in a palm-sized form factor.
