Re: Guide dogs on wheels !


goshawk on horseback
 

in my view, it's a question of which would you rather buy?
A, something that does a job up to a point, but has a number of limitations, so is only reasonably useful.
or B, even if it is a bit more expensive, something that is really useful in virtually all places/environments, and that can really help as well.

I know which I would choose.

Simon, I think you have some great ideas. These ideas could
make the guide dog on wheels be almost as good as a guide
guy like my husband.

Importance: High

sounds like a good start, but I can think of a few possible
improvements, as
follows:
1, giving it gps and maps, to A, improve accuracy further,
and B, actually work out routs, either when in a new area,
or for those who have little or no sense of direction, so
don't have any routs to teach it.
2, giving it OCR, which could be used for all sorts of
things, such as reading road or shop signs, to improve it's
accuracy still further, and making it more useful in places
like shopping centres, reading bus info, which could help
one find the right bus, and get off it at the right place,
and probably a range of other uses.
and 3, giving it proper legs and walking movements. I say
this, as only giving it wheels would make it very limited in
indoor environments, such as department stores, shopping
centres, hotels, blocks of flats, airports, train stations,
the tube, etc. where there could well be stairs or
escalators to be used, or even things like rough ground for
those in to country walks. where as with legs and the right
movements, it could very probably navigate these as well.

don't get me wrong, I really like the idea, but if it is
going to be really useful, then personally, I do think it
has a way to go yet.

Hi Everyone,
Well, I couldn't pass up this article I copied and pasted

Guide dog on wheels detects obstacles and traffic light
signals
MAY 10, 2021 6:01 AM
Singapore Nanyang Polytechnic students develop a prototype
robot dog for the
visually impaired that reads out directions and even "barks.
What is the prototype called and how does it work?
The e-Guide Dog is equipped with laser scanners that detect
when an obstacle
is in the way. It can also be programmed with preset routes
that will give
its user directions.
The e-Guide Dog can detect and will even alert users to
oncoming cyclists by
playing the sound of a dog barking.
Instead of a leash, the user holds onto a handle attached to
the wheeled
device as it is pushed by the user.
What are the main functions of the e-Guide Dog?
The e-Guide Dog has three key functions
The e-Guide Dog records and replays travelling paths up to
an accuracy of
one metre.
It is equipped with a built-in digital compass that records
paths users
take. The data is provided by encoders at the e-Guide Dog's
wheel. These
encoders
monitor the robot's wheel revolutions and steering angles to
provide a more
accurate guide for users.
Obstacle Detection:
The robot is equipped with laser scanners that detect
obstacles in the way.
It then navigates its user around them, preventing accidents
from occurring.
Traffic Light Signal Detection:
The e-Guide Dog is also equipped with artificial
intelligence that can
identify when traffic light signals turn from red to green.
The robot will then alert the user when to cross the road.
This detection is
a plus for the e-Guide Dog as regular guide dogs are colour
blind and unable
to detect colour changes.
The e-Guide Dog was developed by a team of more than six NYP
students across
several semesters who were led by Dr Kong Wai Ming, lead
specialist of the
biomedical engineering and materials group at the
polytechnic's School of
Engineering.
The project is backed by the Enabling Lives Initiative Grant
by SG Enable,
an agency that supports people with disabilities, and the
Tote Board. The
grant
funds innovations that support persons with disabilities.
On Wednesday May 5, the project earned recognition from Dr
Maliki Osman,
Second Minister for Education, during the polytechnic's
graduation ceremony.
In his speech, Dr Maliki said the project was an example of
what NYP stands
for - "innovation and enterprise, anchored in service to
those around us."
Was there any collaboration with the blindness community
during development?
During development, the team worked with Guide Dogs
Singapore - the main
charity in Singapore that pairs guide dogs with the visually
impaired - to
test
the device.
Vanessa Loh, the General Manager of Guide Dogs Singapore Ltd
said that the
e-Guide Dog would serve as a useful mobility aid for persons
with visual
impairment.
Are there any other uses for this technology?
The NYP team adapted the technology behind the e-Guide Dog
onto a cane,
which was fitted with sensors and encoders on wheels to
provide wayfinding
instructions,
which they showcased at an exhibition at the National Museum
of Singapore
last December. the team is seeking to improve its robot
guide dog by working
with industry partners and hopefully commercialize the
project.
