초록 ▼

Surmounting obstacles in the path of a robot vehicle is accomplished by rotating the wheel forks of the vehicle about their transverse axes with respect to the vehicle body so as to shift most of the vehicle weight onto the rear wheels, and then driving the vehicle forward so as to drive the now lightly-loaded front wheels (only) over the obstacle. Then, after the front wheels have either surmounted or completely passed the obstacle (depending upon the length of the obstacle), the forks are again rotated about their transverse axes so as to shift most of the vehicle weight onto the front wheels. Then the vehicle is again driven forward so as to drive the now lightly-loaded rear wheels over the obstacle. Once the obstacle has been completely cleared and the vehicle is again on relatively level terrain, the forks are again rotated so as to uniformly distribute the vehicle weight between the front and rear wheels.

대표청구항 ▼

A method of operating a vehicle supported on front and rear wheels connected to the vehicle body by respective front and rear struts, the front struts and the rear struts being independently rotatable about respective forward and rear axes, wherein the axes intersect the vehicle body in a direction transverse to the direction of vehicle travel, said method comprising the steps of: rotating the front struts simultaneously about their transverse axis with respect to the vehicle body from an original angular position to move the front wheels forward so as to shift most of the vehicle weight onto the rear wheels; driving the vehicle forward by powered rotation of at least some of said wheels so as to drive the now lightly-loaded front wheels over an obstacle; returning the front forks to their original angular position while rotating the rear struts simultaneously about their transverse axis with respect to the vehicle body to move the rear wheels rearward so as to shift most of the vehicle weight onto the front wheels; and driving said vehicle forward by powered rotation of at least some of said wheels so as to drive the now lightly-loaded rear wheels over the obstacle.
