1. An apparatus for measuring the steering angle of a wheel assembly comprising a suspended wheel mount and at least one suspension arm, the apparatus comprising:
a reference bracket comprising a measurement end and a mounting end;
a rotating bracket comprising a measurement end and a mounting end; and
an angle sensor, configured for measuring an angle between said reference bracket and said rotating bracket about a rotation axis of said angle sensor,
wherein said measurement end of said reference bracket and said measurement end of said rotating bracket are rotatably coupled about a rotation coupling point such that said reference bracket and said rotating bracket can rotate with respect to one another;
wherein said mounting end of said rotating bracket is coupled with said suspended wheel mount and said mounting end of said reference bracket is coupled with said at least one suspension arm; and
wherein said mounting end of said reference bracket is positioned on a plane defined by a steering axis of said suspended wheel mount and a rotation axis between said at least one suspension arm and said suspended wheel mount during vertical motion of said suspended wheel mount, said vertical motion being relative to a reference frame, thereby keeping said rotation axis of said angle sensor aligned with said steering axis during vertical motion of said suspended wheel mount.
