Latest Patents
One of Marshall's latest patents is a guidance, navigation, and control system for a vehicle. This invention provides a method and system that allows an underground mining vehicle to be taught a route by a human operator. The vehicle can then automatically drive the route without any human intervention. The method consists of three steps: teaching, route profiling, and playback. During the teaching phase, the vehicle is manually driven along a route, logging data from vehicle-mounted sensors. In the route profiling step, this raw data is processed into a route profile, which includes a desired speed as a function of distance along the path.
Another notable patent by Marshall is similar in nature, focusing on a guidance, navigation, and control method for an underground mining vehicle. In this system, an operator guides the vehicle along a route while motion data is logged by the vehicle-mounted sensors. This data is then processed into a route profile, which includes a vehicle path and a sequence of submaps. The vehicle can subsequently repeat the route autonomously, using the logged data to determine its location.
