Rack and Pinion
Utilizes a rack and pinion gear system to turn rotational (steering wheel) motion into linear motion, which in turn moves the other linkages to make the wheels turn.

http://www.fsae.com/forums/showthread.php?3825-Anti-Due to the lack of pre-existing experimental data, it was decided that pro-ackermann and parallel steering components will be designed and manufactured. The parallel steering geometry will be used to collect experimental data of the new ties in various toe conditions while running on a skid-pad. There is a correlation between toe and ackermann, so by running our own experiment, we can determine the amount of ackerman desired by the new tires. The only difference between the pro-ackermann and parallel steering components should be an adjustable tie rod (to adjust toe). Pro-ackermann will be run on MSXIV due to the majority of solar car teams running 100% ackermann.

Steering Architecture
Left: Steering architecture top-down view; right: side-vide of steering architecture past the fire wall.
From the upright to the steering arm, there will be bolted connections to attach the two together rigidly. The tie rods will have rod-ends (spherical bearings) or clevises as the connection point depending on what is needed, same with the center link. The centrelink will be connected to the rack using either a rod end (and bolted) or using a set screw and jam nuts. Past the firewall, there will be a female spline rod to connect with the male spline end of the rack. Connected to the female spline will be a male spline rod, connected to a u-joint (to allow for tilt adjustability of the steering wheel) along with a tilting mechanism similar to the one shown below. Lastly, there will be a male spline connecting steering wheel to the u-joint with a telescoping mechanism (will probably require a female spline with a slide fit and pins for adjustability). The column will be held up using a mounting jig with a collar and L bar with a shear pin (to allow for collapse).
