machines,” says Knuth.
The Intellibot relies upon on-board
diagnostics to continually record and
monitor its performance. Among the
diagnostics are various sensor tests that
ensure the sonars, floor sensors, and
gyroscope are working properly and
performing within acceptable parameters.
The robot uses the output diagnostics
to test the various cleaning effectors.
“Dan Daly, my senior software
engineer, wrote a program for the
robot called Puppy. Puppy uses sonar
data to detect a person and then
moves the robot to try to follow them
as they walk around the room. This is
a very effective way to verify not only
that all the subsystems are working,
but also that they are working
together,” explains Knuth.
According to Intellibot, the robots
will page their human operators only
when they encounter issues that they
can’t resolve on their own. In fact, the
robots surprise their engineers with how
little they need to be guided by their
operators. That’s because the robots
will often perform better than expected.
“Once, the robot came down a
grocery aisle and missed the next aisle.
It went four feet, stopped, and backed
up, then went down the correct aisle.
That’s not something we [specifically]
programmed in. It simply used its
logic to make a correct decision after
making a mistake,” says Knuth.
The existing Intellibot Robotic
Floor Cleaners (the IV800 Robotic
Vacuum, the IS800 Robotic Floor
Scrubber, and the IS800c Robotic
Sweeper Scrubber) are the
culmination of nearly two decades of
research. Intellibot robots now clean
hospitals, office buildings, academic
and healthcare institutions, factories,
retail stores, grocery stores, malls,
hotels, warehouses, and airports.
They do all this with a 100 percent
accident-free record to date.
Intellibot continues its research in
anticipation of adding more cleaning
robots and new models to the existing
line in years to come. “We have an entire
family of machines on the drawing board
with some very interesting features,” says
Knuth. In the future, the product line
will meet new and expanding cleaning
needs in commercial markets. SV
