    Part of the benefit of having a guide dog is that it can be a true companion to a blind person, and many times more trustworhty than a robot. A dog isn't going to crash and require a reboot, and kibble is easier to figure out than rechargeable batteries.

    That said, computers and robotics are a reflection of their creators. I guess I trust dogs a whole lot more. A dog can also provide protection against burglars. The benefits of dogs over robots goes on and on.

      I would have to disagree, a guide dog does not know where the library is, or the computer store, or your house, whereas a robotic dog will(does?) have a map and be able to direct you to the location. This robot sounds like a great idea, a good use of technology.

    A professor in computer science at the Utah State University (USU) is building robots to help people with disabilities, according to the Utah Statesman in this article [utahstatesman.com]. The story, which is more focused on the professor than robotics, carries several anecdotes, such as an embarrassing voice recognition system. After a blind man cleared his throat, the robot misinterpreted the sound as a sign that the man wanted to go to the bathroom. Later, every time a man cleared his throat before speaking, the robot changed directions and insisted to guide him to the restrooms. Even if the article is entertaining, this project at USU is far more ambitious. In fact, they want to design RFID-enabled robots mounted on mobile carts which will welcome blind persons at the entrance of a supermarket and guide them through the store. I bet you'll never find those carts at a Wal-Mart store, but read more...

    First, let's look in detail at the failure of the voice recognition system.

    Vladimir Kulyukin, assistant professor in the department of computer science, works jointly as a computer science researcher and for the

    Center for Persons with Disabilities [usu.edu]. He said he had an especially embarrassing moment here at the Center for Persons with Disabilities involving a robot and a speech recognition system.

    "We figured we could speak to the robot in English, and using the voice recognition system the robot would interpret the commands and obey them. I quickly realized that just wasn't possible," he said.

    He said a blind man found the glitch in the system when he cleared his throat and the robot misunderstood the sound to mean the man wanted to go to the bathroom.

    "Every time the man cleared his throat, the robot would immediately change directions and guide him into the bathroom," he said. "It was an especially embarrassing moment in my research," he added.

    Of course, this is only a very small part of the project, which will deploy radio frequency identification (RFID) tags for use in robot-assisted indoor navigation for the visually impaired.

    "Simply speaking, we are trying to develop a robot for use as a mobile grocery cart used for the blind in supermarkets," he said. "The robot would meet the blind person at the door and, by the push of a button, would lead the person to different areas of the store."

    Kulyukin said the robot would ideally be mounted on mobile carts, but the level of funding for the technology here at USU is not sufficient for marketing the project.

    But they already built prototypes. And below are two pictures showing this RFID-equipped robotic guide (RG) for visually impaired people (Credit: Vladimir Kulyukin)

Those robots could recognize customers by their voice, fingerprint (blind people will touch them) or simply customer card. Them they can make all posts of suggestions.

      Exactly. Walmart already has carts with motors for disabled shoppers. They also have a "greeter" by the door who can easily recognize blind people entering the store and direct them to this special cart.

      This is the sort of thing companies like Walmart love. It costs very little, and looks very good even to those who will never need it.

        I actually work as one of those greeters (which isn't as easy as it sounds, most of the time), so I know the carts you speak of and the people who use them.

        I've not once had a blind person driving one of those things. They're just motorized carts. They don't know where you want to go.

        Hell, I don't trust some of the sighted people with driving those things! They'll forget how to stop (let go of the controls, it's not hard!) and end up hitting the wall, the door, merchandise, or you.

        The blind people who DO enter are almost always accompanied by a friend who helps them through the store. (even when they have a service dog)

      The guidance system needs to be simple, reliable, and cheap. You don't need a camera or optical reader of any sort.

    I'd like to see a projected cost-benefit analysis for robots vs service dogs. My sister is raising a puppy that will eventually become a service dog for people with hearing disabilities and other challenges (but not blindness). As a puppy raiser, my sister encounters several challenges, both financial and social:

    permission from her landlord to raise a puppy for 18 months

    permission from her employer to bring the puppy to work every day

    mandatory attendance of weekly training courses

    purchases of collar, leash, haltis

    responsible for any medical costs under $500

    daily socialization, including shopping malls, grocery stores, buses, doctor's and dentist's offices, theatres, movies, restaurants, elevators and sporting events.

    (This is particularly challenging, since many store owners refuse to admit the dog, despite my sister's possession of a government-issued ID that explains the dog is a service dog. People often say, "But you're not blind!" -- they don't understand that people with hearing problems, as well as invisible disabilities, have these dogs, let alone that people need to train them first.)

    Raising a puppy is serious work, but imagine you also need to teach that puppy to ignore food, stop at crosswalks, not chase sticks, ignore animals, and otherwise suppress many instincts. This requires an enormous amount of energy.

    Those are just the requirements for the people raising dogs from 10 weeks through 18 months. For breeders and caretakers of puppies under 10 weeks, the people cannot work outside the home -- and they must take on many of the same challenges as the puppy raisers. As for dogs who finish basic training (at 18 months), many must move on to basic training with new trainers, who take on much the same role as the puppy raisers. Finally, after all of this work, the dog can be placed with a client (person with a disability) for specialized training.

    Recruiting puppy breeders, raisers, and advanced trainers is a challenge for service dog societies, which also need to subsidize food, training and other products. And clients will eventually need to feed and care for the dogs. This is not a small amount of money.

    Given all of these challenges, it would be interesting to see how a robot stacks up. If a robot cost $10,000 plus batteries, perhaps this is not actually much higher than the "value" of a dog that has been through 18+ months of training and must still be fed and cared for -- volunteer time and effects on the puppy raiser's workplace productivity should also be included in the calculation. Certainly, a robot may not provide companionship, but it may not be such a bad idea. With more time on their hands, volunteers could actually provide other programs for clients. Robots could be pre-programmed, so that the first 18-24 months of dog training could be skipped. And you don't need to buy kibble for a robot.

    • I know this sounds cheesy, but the value of the companionship offered by a dog is something you haven't taken into account (and, indeed, can't have a dollar value assigned to it). I don't pretend to know anything about it, but I would imagine that having a disability such as visiom impairment would be socially isolating to a certain degree (most differences tend to have this effect in society, even those that don't limit mobility). The therapeutic value of having a pet is not to be ignored (a dog doesn't ch

        So it would be interesting to see a comparison of the projected cost of a robot vs. that of a $25,000 assistance dog. If the robot la

I'd understand the use of some kind of transponder system (WLAN, GPRS, UMTS...) for real data communication, either with a central (map) server, or even other robotic dogs in the surrounding, but I don't see the need for a short range identification tag.
  • This article caught my eye because I am a robotics researcher. Although I admire the intentions of the project, I think such a system design is hard to justify given other alternatives.

    Here are some thoughts:

    1) Using RFID tags for robot localization is inaccurate and probably not the best choice for fairly structured indoor environments like supermarkets. Just putting colored/patterned tiles on the floor or ceiling, or using indoor GPS would probably allow the robot to navigate better.
