<p>An automatically guided vehicle (V) having a steering mechanism for enabling the vehicle to follow a guidance wire is disclosed. The vehicle includes a pair of spaced-apart steer drive antennas (S1, S2) and a pair of spaced-apart differential drive antennas (D1, D2). The steer drive antennas and differential drive antennas are in mutual perpendicular relation to each other and are stationarily mounted on the vehicle (V). In a steer drive mode, wheels (12) and (13) are separately controlled by steer drive antennas (51) and (S2), respectively. The antennas cause the wheels to turn and therefore guides the vehicle (V) so that a wire (W) is followed.</p><p>In a differential drive mode, wheels (12) and (13) are positioned in parallel driving relation to each other and are controlled by antennas (D1, D2) respectively by varying the speed of the wheels (12,13) to cause the vehicle (V) to follow the wire (W).</p> |
