The first support member pivotably connected to the body via a first axis such that pivoting movement of the first support member about the first axis as a result of a first torque about an axis has a component about an axis transverse to the direction of travel such that engagement of the rollers with the ground causes a second torque on the first support member opposing the first torque.
