Service Robots Kyler Tolman 12/9/2014. Definition Service robots assist human beings, typically by performing a job that is dirty, dull, distant, dangerous
Definition Service robots assist human beings, typically by
performing a job that is dirty, dull, distant, dangerous or
repetitive, including household chores.

History
Slide 5
Mowbot Initially sold in 1969 Cost $700 ($4500 today) Used a
buried perimeter cable for navigation Due to the high price the
mower quickly faded into obscurity.
Slide 6
Current State In 2013, 4 million service robots for personal
and domestic use were sold, 28% more than in 2012. As of 2013
iRobot alone has sold over 10 million home robots worldwide. The
fastest growing market in robotics.
Slide 7
Where used
Slide 8
Vacuum Cleaners Largest segment of domestic robots First robot
- Electrolux trilobite in 1997 Cost $1,400 Run time 1 hr. Used
ultrasonic sensors for navigation Did not do well due to high price
point
Slide 9
iRobot Roomba First launched in 2002 Cost $200 Uses simple bump
sensors for navigation. Sold 50,000 units the first year, sold over
a million by 2004. iRobot has sold more than 10 million robots by
2013
Slide 10
Costs No name brands - $150- $400 Roomba - $350 - $700 Dyson
DC06 - $6000
Slide 11
Supporting Technology Roombas do not map out environment but
use simple bump sensors and proximity sensors. Roombas incorporate
spiraling, room crossing, wall following, and random walk angle to
accomplish cleaning.
Slide 12
Supporting Technology Navigation Techniques o Spiraling o Wall
following o Room Crossing o Random Walk angle Multiple passes
ensure coverage of the floor
Slide 13
Supporting Technology Dyson has developed a proprietary machine
vision system for their 360 Eye robot. Dyson has spent 16 years and
over $47 million dollars in the development of this vacuum.
Slide 14
Supporting Technology Dysons 360 eye finds high contrast
features in the room and uses them to triangulate its
position.
Limitations Battery life Amount of time required to clean
Cleaning pattern is somewhat random Robots can become trapped in
corners, tangled on cords, sat on by cats etc

Slide 18
Robotic Lawn Mowers
Slide 19
Market has existed for over 20 years Almost all mowers use a
buried boundary wire to mark off area to be mowed.
Slide 20
Costs $1200-$5000 for kit Husqvarna Automower - $2400 Robomow
RC306 - $1200 Battery replacement and other maintenance can add
additional costs.
Slide 21
Supporting Technologies Similar technology as used in AGVs:
guide wires, electromagnetic charging stations etc GPS as well as
machine vision are used in navigation
Slide 22
Limitations Battery life Has difficulty cutting tall grass
Requires permanent boundary wire installation Difficulty to finding
replacement parts Overall costs

Paper Goth, Gregory I, Domestic Robot Advances in sensor
technology, specifically laser range finders, and faster algorithms
are increasing domestic robots semantic and situational awareness.
Falling hardware prices for sensors and processors are enabling
more affordable domestic robots. The robot to the right, using
machine vision was able to fold 50 out of 50 towels
successfully.
Slide 26
Summary The domestic robot market is rapidly expanding
Supporting technologies such as machine vision and navigation
algorithms are allowing for more truly autonomous robots.
Decreasing prices in supporting hardware such as sensors and
processors are allowing for more affordable robots. This is an
exciting field of robotics with a lot of opportunities.
