SLAM ENGINE

Modular LiDAR SLAM Engine That Never Loses Localization

Navi-Answer (ANSWER) packages the core SLAM technology of Navifra as an independent module. Its modular structure combines map-based, LiDAR Odometry, Intensity, and 3D positioning to match field conditions, and can be supplied independently to third-party robot platforms.

4 features

Modular Positioning Architecture

Combine and select map-based, LiDAR Odometry, Intensity, and 3D positioning to match field conditions. Respond with module selection alone without per-site algorithm redevelopment.

Real-Time Automatic Positioning Switching

Automatic switching between map-based positioning and LiDAR Odometry during driving maintains positioning continuity even in environmentally variable zones. Occurs without robot stopping.

Intensity-Based Positioning

Identifies position using LiDAR reflector intensity differences in environments with insufficient geometric features such as long corridors and repetitive racks. Less installation and maintenance burden compared to QR/markers.

3D LiDAR + IMU Fusion Positioning

Performs 6DoF positioning in multi-story buildings, ramps, and outdoor environments. No need to redesign SW architecture when expanding from 2D to 3D.

Any Environment Handled by Positioning Module Combination: No Redevelopment

ANSWER modularizes 5 positioning methods (map-based, LiDAR Odometry, Intensity, hybrid, 3D) and combines them to match field conditions. Long corridor → Intensity, map mismatch → automatic LiDAR Odometry switching, outdoor → 3D. Only the combination needs to change on the same architecture, so per-site algorithm redevelopment is unnecessary.

Independent Module Supply: SLAM-Only Adoption Without Navi-Core

ANSWER is built into Navi-Core by default but can also be supplied separately as an independent license to third-party robot platforms. Provided in ROS1/ROS2, x86/ARM independent structure for customers who have their own path planning and motion control but only need SLAM.

Independent license supply to third-party robot platforms
ROS1/ROS2, x86/ARM platform-independent structure
Built-in performance analysis UI + Logger for efficient field tuning
External sensor fusion interface (GPS, Camera, wheel encoder)

Compatibility & Integration

A compact add-on design mounts directly on a wide range of robot platforms. Standard interfaces make it easy to connect with your existing infrastructure.
