Robot rental service for Outdoor Surveillance

by Dhiram Shah

SECOM Co., Ltd. has developed the “SECOM Robot X,” a security robot to monitor around buildings such as schools, housing complexes, plants etc. The service charge is expected to be ¥300,000 per month ($ 2750) for combined use of a robot and a surveillance system which is 50% cheaper than the cost of hiring a security guard on 24 hour service. However it costs 4.5 million Yen to built a patrol route. ($ 40,000). The robot’s key features are as follows: (1) It can travel at 10 km/h, a speed of a human jogging moderately, (2) An all-around view camera mounted on top of the robot enables to survey areas, which are blind spots for fixed cameras and difficult for human security guards to go in, (3) To prevent crimes, it can threaten intruders with voice, sound, light (flashing) and smoke from an optional smoke emitter (4) It features a fire sensor to detect suspicious fires and start an optional automatic fire extinguisher to stop fires at an early stage, and (5) By positioning the robot at near the gate or the door, users can monitor humans and cars entering and leaving the building and keep their records.

The SECOM Robot X is a two-wheel drive automobile robot on
four wheels. In addition to "auto drive" mode, in which the robot
follows a patrol route on a pavement with a magnetic guide line using a
build-in magnetic guide sensor positioned at the bottom, the robot can also
be operated in "remote control drive" mode using a surveillance
system via WLANs and "remote control" mode using a wired remote
controller. To liberate the surveillance center from issuing commands every
time the routine is executed, "markers" to send commands to the
robot are installed at every pivotal point of the magnetic guide line.

The robot measures 1,225 (L) x 840 (W) x 1,120 (H) mm and weighs approximately
230 kg. The rechargeable battery unit uses two 12 V, 50A lead cells connected
in series. The battery can run the robot for about two hours when the
robot continuously travels at 3-4 km/h. Full recharge reportedly takes
about 1 hour. The company assumes battery chargers would be located in
a patrol route.

Multiple WLAN base stations are also scattered in a patrol route. Images
captured by robot’s cameras are monitored in real time at the surveillance
center. In times of emergency, the center can switch the robot to remote
control drive mode and speak or play sound through the robot’s speakers.
As for cameras, the robot features a pan tilt zoom camera in front upper
part, and an all-around view camera system, consisting of six cameras
aligned like a ring at even intervals, in rear upper part.

To detect obstacles, laser sensors are embedded right beneath the abovementioned
pun tilt zoom and all-around view cameras, as well as ultrasonic wave
sensors fitted on front and the back of the body. The laser sensors are
for obstacles at a distance of about 10 m and the ultrasonic wave sensors
are for those about 4 m away from the robot.
