Charging system
First Claim
1. A device for providing power to a target device, comprising:
- a movement system;
a power cord;
wireless circuitry that is configured to gather wireless beacon signals;
control circuitry that is configured to direct the movement system to move the control circuitry and power cord along a path on a surface based at least partly on the wireless beacon signals to deliver power from the power cord to the target device; and
at least one sensor, wherein the control circuitry is configured to control the movement system to guide the control circuitry and power cord around foreign objects detected with the sensor.

Abstract
A mobile charging device may be used to move a battery or a power cord to a target device. The target device may be a vehicle or other equipment with a battery. Power from the power cord or battery in the charging device may be used to provide power to the target device to recharge the battery in the target device. The charging device may couple a power cord to the target device, may couple a connector in the charging device to the target device, or may use a wireless power transfer element such as a coil antenna to transfer power wirelessly to the target device. Sensors may be used to facilitate alignment between the charging device and target device. Sensors may also be used to dynamically detect and avoid foreign objects in the path of the charging device.
