V. CONCLUSION
The design and implementation of a battery swapping and
wireless charging robot system have been presented for
home automation applications. A four-wheeled base is used
to provide mobile capability for the robot. A six degree-offreedom
manipulator is adopted to grasp the dead battery
and swap it with a charged one. The wireless charging
method decreases the complexity of the battery swapping
process. A remote control system with visual feedback is
used to help the user control the robot remotely. The
experimental results show that the peak charging current is
about 725 mA. The charging time is about 8 hours for a
4000 mAh battery. The robot can swap its battery in about
62 s with the assistance of a remote operator. The robot
system can be used in indoor environments for home
automation.
