  • Apparatus for measuring the displacement of a vehicle, in particular an all-terrain robot, and a vehicle equipped with such apparatus
    Patent number: 5410478
    Abstract: A primary odometer velocity is measured by a sensor on an odometer member travelling over terrain. The velocity is corrected by a calculating unit to take account of the inclination of the terrain at the point of contact where the member is in contact with the terrain. The inclination is measured by means of force sensors, e.g. measuring the forces applied to said member as a whole. An inertial unit supplies the orientation and the angular velocities of the vehicle. The device has application to navigation of all-terrain robots.
