Gokart Stepper Power Steering Help

In summary, the conversation discusses the use of stepper motors for a makeshift power steering system in a Gokart with regenerative braking and UltraCapacitors. The speaker is seeking help in calculating the required torque/force for the motors to turn the wheels at rest, considering factors such as coefficient of friction, normal force, and weight distribution. They also mention the importance of mechanical trail and scrub radius and provide a resource for further information.

Hello PF, A friend and I are building a rather cool Gokart with regenerative braking and UltraCapacitors etc...

Instead of using conventional mechanical steering we plan on using stepper motors for a makeshift power steering system

My question is I can't figure out the required Torque/Force the motors need in order to turn the wheels at rest. I know that as your speed increases you need less force to steer so if I calculate for rest I can cover everything.

I know my calculations need to include: Coeffecient of Friction and Normal force, and that torque = radius * force, but I don't know which radius to use.

The weight of the kart is about 400lbs with the majority at the back with the motors etc..

Any help would be much appreciated.

It is all about the mechanical trail and scrub radius. See http://www.optimumg.com/OptimumGWebSite/Documents/OptimumK%20Help%20File%20v1.1/KPI%20_%20Caster_legacy.htm" for more info.
