Casualty Evacuation UGV: Self-Leveling Stretcher Platform

Interactive 3D simulator of a battlefield casualty-evacuation ground robot: watch a PID-controlled self-leveling stretcher platform cancel chassis pitch/roll as the vehicle crosses rough terrain, and compare it against a rigid mount with the leveling turned off.

A battlefield casualty-evacuation ground robot has to cross rubble, ruts and uneven cover while keeping an injured passenger stable — a rigidly mounted stretcher would tip and roll with every dip in the ground. This simulator drives a six-wheel UGV along a looping cross-country path over a procedurally rough terrain field, computes the chassis's own pitch and roll from its four wheel-contact heights each frame, and drives four independent vertical actuators to cancel that tilt so the stretcher platform stays level. Toggle self-leveling off to see the same robot with a rigidly bolted platform instead, adjust terrain roughness and carried load to stress the control loop, and watch live pitch/roll, actuator extension and a tip-over stability margin update in real time.

⚙ Under the hood

Drive a six-wheel casualty-evacuation ground robot across procedurally rough terrain and watch four PID-driven actuators cancel chassis pitch and roll to keep the stretcher platform level, or switch leveling off to see it tip with a rigid mount.
