Commercial robot interfaces such as iRobot’s Packbot, Foster-Miller’s Talon, Remotec’s

Andros and American Standard Robotics’ VGTV Extreme, two of which are shown in figure 5,

generally are made up of one or more video streams. If the robot has a mechanical arm, the

interface may include a visualization which shows the current position of the mechanical arm.

However, other sensors such as SICK lasers and sonar sensors are not mounted on the

platforms. There are various reasons to blame for commercial robots not being equipped with

robust sensor arrays. First, many of the sensors are expensive; therefore including them on the

platform would drive the price up of the unit. Also, many of the sensors are too large to fit on

the compact platforms and require more power which reduces time needed before recharging.

Additionally, many of the sensors are not rugged enough to survive the extreme conditions that

many of the commercial robots are forced to deal with. These reasons and more, add up to

commercial robots consisting mainly of platforms with multitudes of cameras on them, with

little else in the way of additional sensors.

All commercial robots, of this type, are teleoperated. They do not have enough sensing power

to be able to complete the complex task of performing autonomous behaviors, so there is always

a human operator at the control station performing all the tasks to be completed. Generally the

robot control teams in the Army, for instance, consist of two or more people. One person is

designated solely to drive, while other people are designated to scan the video for important

information, while another person may be designated to hand draw a map of what the area looks

like as the robot is being controlled through the environment. In the future, when sensors are

cheaper and more rugged, autonomous behaviors will eliminate the need for more than one

person monitoring the system. They may even afford the ability to have one person effectively

monitor multiple robot systems at once, but unfortunately, we are not at that stage for

commercially available platforms.
