=Ackermann steering design=

In short, steering designed such that lines extended from the axles of all wheels meet at the centre of the radius of a turn. Spreadsheets and general information: http://www.eland.org.uk/steering.html

=2008 Design=

Although the exact specifics are not firm, we are designing the chassis around a system inspired by the Catrike steering system. It uses a bicycle headset for bearings:



=Probelms with Existing Design=

The U-joint is really, really weak and has a lot of play. It keeps breaking (it is currently broken) and was never really good to begin with.

An upgraded, beefy, overengineered ujoint could work well.

=Rod-based=

I snapped a picture of UBC's steering system, which uses just a few rods:



=Rear Wheel Steering=

Some kind of rear wheel steering design would allow us to make like the ETH PAC-Car II and really reduce frontal area. Unfortunately we have a motor and a static chainline to deal with. Any ideas?
