mobile robots based on sound source is presented [15]. A
simple semi-circular recharging station for automatic docking
and recharging of a surveillance robot is introduced [16]. A
novel docking station and a hybrid control scheme [17] are
proposed for automatic docking and recharging of electric
vehicles.
The robots using docking stations for battery recharging
mentioned above need to stay in fixed positions during the
battery charging process. Therefore the robot cannot work
continuously. Many researchers begin to develop robot
systems with the capabilities of battery swapping and charging.
When the battery voltage is lower than a preset threshold, the
robot can exchange it with a charged one. The authors [18]
design a novel robot docking station for automatic battery
exchanging and charging. The battery can be exchanged
automatically within 45s. K. A. Swieringa et al. [19] design an
autonomous battery swapping system for small-scale
helicopters. The authors [20] design and analyze an automatic
battery replacement system for Unmanned Aerial Vehicles. Y.
Saito et al. [21] develop a battery support system using
support robots to deliver fresh battery to working robots. This
method can decrease the interruption time of the working
robots.
The proposed battery charging systems above need
mechanical and electrical connections between the charging
station and the battery. The docking process also needs high
precision. With the development of wireless charging
technology, wireless charging becomes a feasible solution for
charging of portable electronic devices [22], [23], wireless
sensor network nodes [24], [25], and electric vehicles [26],
[27]. A contactless charging platform [28] can be used to
charge multiple robots simultaneously. The batteries of the
robots finish charging in about 3 hours.
Wireless battery charging allows the robot to plug the dead
battery into the charger on the charging station within a larger
docking range and does not need a tight connection between
the charging station and the battery. In this paper, the design
and implementation of a battery swapping and wireless
charging robot system are presented for home automation
applications. A six degree-of-freedom manipulator is mounted
on a four-wheeled robot base. The manipulator can grasp and
