1. A robot for collecting a rollable object capable of a stable upright position and a stable horizontal position, said robot comprising:
(a) a center of mass, a front end, a rear end, a midpoint, and an axis of rotation, wherein the center of mass is between the front end and the midpoint, and the axis of rotation is the axis about which the robot rotates when tilted between the upright position and the horizontal position; (b) a first load-bearing wheel supporting the robot forward of the midpoint, having a radius (r), positioned so that the robot may be rotated at least 45° from the horizontal position along the axis of rotation without the front end coming into contact with the ground; (c) a mobile load-bearing support structure supporting the robot rearward of the midpoint while in the horizontal position; (d) a drive motor providing rotation to a drive wheel; (e) an energy source providing energy to the drive motor; (f) a rotating collector proximate to the front end; (g) a holding basket having a first basket position, in which said holding basket is positioned to receive the rollable object from the rotating collector while in the horizontal position and in the first basket position; (h) a controller connected to provide control signals to the drive motor; and (i) a sensor connected to provide data to the controller. |
