Magnetic Apparatus for Centering Caster Wheels

An autonomous delivery vehicle having one or more caster wheels that may be held off the ground for a portion of the time that the autonomous delivery vehicle travels. Each caster wheel is mounted in a pivot with a centering mechanism to hold the caster wheels in a design orientation. The caster wheel in the design orientation maximizes the view of forward-looking sensors on the autonomous delivery vehicle. The centering mechanism uses magnetic attraction/repulsion to center the caster wheel. The centering mechanism may incorporate a plurality of permanent magnets and or electro-magnets.
