Battery powered object-gathering apparatus

An object-gathering apparatus comprising:

• a chassis;
• a plurality of wheels coupled to the chassis and configured to traverse a surface;
• a receptacle coupled to the chassis;
• a battery clip affixed to the chassis and accessible from an exterior of the object-gathering apparatus, wherein a rechargeable battery is removably insertable into the battery clip;
• and
• a sweep assembly coupled to the chassis and configured to transfer objects from the surface into the receptacle by mechanical action on the objects, and without use of negative pressure or vacuum suction acting on the objects during the transfer, in response to powered rotation of the sweep assembly by the rechargeable battery.
