A self-propelled device is provided including a drive system, a spherical housing, and a biasing mechanism. The drive system includes one or more motors that are contained within the spherical housing. The biasing mechanism actively forces the drive system to continuously engage an interior of the spherical housing in order to cause the spherical housing to move.
