An automatically guided vehicle (2) for towing a load (32) is disclosed. The vehicle includes a first body portion (4) and first wheels (6, 8) mounted to the first body portion engage a surface supporting the vehicle. The first wheels are driven at different rotational velocities to cause the first body portion to pivot about a first pivot axis (16). A second body portion (22) is mounted to the first body portion and engages the load. Second wheels (26, 28) are mounted to the second body portion and engage the surface supporting the vehicle. An electromechanical bolt (30) has a first condition in which the first body portion is pivotable relative to the second body portion and a second condition in which the first body portion is prevented from pivoting relative to the second body portion.
