An automatic track width adjustment system is provided for an agricultural mobile robot (AMR) 1 having a frame 2 defining a plane and a plurality of wheels 7, 8, 9, 10. The system has an adjustment mechanism for changing the position of at least one wheel relative to frame 2 in a direction perpendicular to a movement direction of robot 1 and within the plane. The AMR may instead have an automatic wheelbase adjustment system comprising an adjustment mechanism for changing the position of at least one wheel 7, 8, 9, 10 in a direction corresponding to a direction of movement of the robot. An AMR is also provided. Adjustment is preferably by movement on linear rails 13, 14, 15, 16. Preferably the positions of at least two wheels, and typically two front and two rear wheels, are adjusted simultaneously so the distance between them is the same. Differential steering and computer vision for determining the track width may be present.
