Abstract
Methods for steering mobile medical equipment are disclosed. In one embodiment, the method includes supporting medical equipment with a base above a floor over which a left steerable wheel, a right steerable wheel, and a pair of front wheels roll; receiving an input steering angle other than zero; linearly sweeping a long link in response to the input steering angle, pivoting a pair of short links in response to the linearly sweeping of the long link; pivoting a pair of cam plates in response to the pivoting of the pair of short links; transferring the pivoting of one of the pair of cam plates to a left wheel assembly to position the left steerable wheel at a left wheel angle; and transferring the pivoting of another one of the pair of cam plates to a right wheel assembly to position the right steerable wheel at a right wheel angle.
