Re: Guide dogs on wheels !

goshawk on horseback

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 below.


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.

Peace Be With You.
