1. An article, comprising:

  • an enclosure defining a three-dimensional body having an ovoid or spherical shape;

    an electric motor disposed within the enclosure, the electric motor including a motor body held in place by the enclosure and a drive shaft;

    an offset mass element disposed within the enclosure and mechanically coupled with the drive shaft of the electric motor;

    an angular position sensor disposed within the enclosure to measure an angular position of the offset mass element relative to the enclosure;

    an accelerometer sensor disposed within the enclosure to measure an angular position of the enclosure relative to a gravity vector; and

    a control system disposed within the enclosure, the control system configured to;

    receive measurements of the angular position of the offset mass element relative to the enclosure from the angular position sensor;

    receive measurements of the angular position of the enclosure relative to the gravity vector;

    vary electrical power supplied to the electric motor to drive the drive shaft based, at least in part, on the measurements of angular position of the offset mass element and the angular position of the enclosure to generate rolling motion of the enclosure relative to a surface upon which the enclosure rests.
