SYSTEM INQUIRIES

// FREQUENTLY ASKED QUESTIONS //
What are the WebGL requirements for the simulators?
RoboAI Suite requires a modern browser with WebGL 2.0 support. Hardware acceleration must be enabled in your browser settings to ensure 60fps performance during 3D point cloud rendering and 6-DOF kinematics.
How does LiDAR raycasting operate client-side?
The SLAM simulator uses a highly optimized 2D line-line intersection algorithm. It casts 360 rays from the robot's center against all wall line segments in the environment grid. Gaussian noise is injected into the distance readings to simulate real-world sensor inaccuracies.
How does NEXUS handle kinematics singularity?
The inverse kinematics (IK) solver uses Damped Least Squares (DLS) with Levenberg-Marquardt damping. When the Jacobian determinant approaches zero (Yoshikawa manipulability index drops), the damping factor prevents joint velocities from tending to infinity, ensuring stable trajectories near singularity zones.
What is Space-Time A* in HIVE Logistics?
Space-Time A* is a 4D pathfinding algorithm (x, y, rotation, time) used in HIVE. It manages a global reservation table so autonomous mobile robots (AMRs) can plan collision-free paths by factoring in the projected future positions of all other active units in the swarm.
