At the forefront of technological innovation, the Queensland University of Technology (QUT) is pioneering a project that could revolutionize assistance for people with vision impairment. ‘Spot’, a robot lacking the familiar features of a dog, is being reprogrammed by QUT students to navigate and assist like a guide dog.
Santiago Velasquez, an electrical engineering student and guide dog user, is driving the project with a personal understanding of the challenges faced by individuals like himself. Velasquez points out the difficulties of international travel with a guide dog, from quarantine processes to the physical toll on the animal, such as paw burns during hot weather. The robotic guide dog could offer a solution to those who need assistance but are unable to care for a live animal.
Spot’s original design was for the oil and gas industry, intended for environments too hazardous for humans. However, Velasquez believes that with the right programming, robots like Spot could significantly reduce the waitlists for guide dogs and provide assistance to those living in remote areas.
The project is not without its challenges. Spot’s rigid structure leads to jerky movements, especially when turning, and it lacks the ability to intuitively respond to obstacles. Velasquez and his team have attached a handle to Spot for guidance and control, but the robot’s current capabilities are limited to stopping in the face of obstructions.
The goal is not to replace guide dogs but to augment the assistance they provide. Velasquez emphasizes the importance of starting to integrate robots into everyday life, much like smartphones have become essential over the past two decades. However, he acknowledges that it may take up to 20 years before a robot could fully replace an assistance animal.
Feedback from five visually impaired individuals has been incorporated into the research, with requests for Spot to move faster and smoother. This user-driven approach ensures that the final product will meet the actual needs of potential users.
Professor Jonathan Roberts, a robotics expert at QUT, sees robotic guide dogs as a transformative tool for the visually impaired. He envisions a future where robotic guide dogs’ training can be easily transferred and updated, unlike live dogs that require years of training.
Guide Dogs Queensland’s Jason McKee, however, remains skeptical. He believes that the companionship and intuition of a live dog cannot be matched by technology. While acknowledging Spot’s impressive capabilities, McKee emphasizes that only about 40% of bred puppies qualify as guide dogs, a testament to the rigorous standards required for the role.
Velasquez, too, holds a special place for his guide dog, Trey, who offers more than just guidance. The companionship and emotional bond between a guide dog and its user are irreplaceable.
This innovative project at QUT represents a significant step towards inclusive technology, potentially expanding the horizons for those with vision impairment.
