Low-Profile Robotic Platform

This invention describes a flat robotic platform designed for testing vehicles, especially those with self-driving features. It includes a unique suspension system for each wheel, featuring a shaft that connects the wheel to a motor through a flexible coupler. The suspension uses springs strong enough to keep the robot off the ground during normal use, but they are designed to flex and allow the robot's body to rest on the ground if it encounters a heavy load or shock, spreading the impact across the chassis.
