  • Power system for ground-based machines
    Patent number: 9484148
    Abstract: A method for distributing energy to a group of ground-based machines. The energy is supplied to the group of ground-based machines through a pattern of inductive power transfer lines physically associated with a ground in a work area. Operations are performed with the group of ground-based machines in the work area. The group of ground-based machines moves in the work area without following a path based on the inductive power transfer lines.
