This paper presents a battery swapping and
wireless charging robot system. A six degree-of-freedom
manipulator mounted on a four-wheeled robot base is used to
grasp the dead battery in the robot and plug it into a charger
on a wireless charging station for recharging. A camera
mounted on the robot provides visual information to help the
user control the robot remotely through any user terminals
with Internet connections. The robot sends visual information
to a home server through a Wi-Fi network
