ARMOR is the premier mobile utility for robotics engineers, students, and researchers. Experience high-performance 3D visualization and physics-based simulation for your URDF (Unified Robot Description Format) models directly on iPhone, iPad, and Mac. Whether you are developing complex kinematics for a collaborative robot arm or fine-tuning the balance of a humanoid model, ARMOR provides a robust environment to inspect and simulate your designs anywhere. KEY FEATURES: • MuJoCo Physics Engine: Leverage the industry-standard MuJoCo engine for high-fidelity physics simulations. ARMOR makes it easy to visualize joint dynamics and collisions on mobile hardware. • Advanced URDF Viewer: Load and inspect your own URDF and XACRO files. ARMOR handles complex links, joints, and geometries with ease, providing a comprehensive engineering view of your robot's structure. • Humanoid & Spatial Robot Visualization: Perfect for visualizing cutting-edge platforms. Load models similar to the Boston Dynamics Atlas or open-source humanoids like the Reachy Mini to study their form and motion in a spatial context. • Robot Arm Kinematics: A vital tool for industrial automation and cobot development. Inspect robot arms like the ABB YuMi and other multi-axis systems with precision. • Augmented Reality (AR): Move from the screen to the real world. Place your robot models in your physical environment at 1:1 scale to assess spatial dimensions and workplace safety. • Engineering Workflow Integration: Designed for the modern robotics services professional.
