First Claim
Patent Images
1. A robotic mower inductive charging station, comprising:
- a horizontal base structure having a plurality of transmitter coils laying substantially flat on an unpaved ground surface for inductive charging a robotic mower, the transmitter coils mounted in a pattern on the horizontal base structure having a first axis, a second axis, and a third axis at an angle between the first axis and second axis for inductive charging of a robotic mower entering the charging station over the transmitter coils along any of the first, second or third axes; and
a plurality of slots, perforations or holes covering at least about 50% of the base structure'"'"'s surface area to permit vegetation growth through the slots, perforations or holes.
