Arizona State University students' robotic guide dog received first prize at the 2018 Intel Cup Undergraduate Electronic Design Contest in Shanghai, China.
The team also designed the prototype for a motorized wheelchair that visually impaired individuals can use with the guide dog.
The robot uses communication protocols such as Wi-Fi and Bluetooth, as well as a specialized behavioral algorithm and Amazon's Alexa technology to understand verbal commands.
A camera on the robot's head captures the surrounding environment, with images fed to the wheelchair's computer and processed through visual recognition and object-filtering systems. As that data is transmitted to the computer, a user can speak a command to Alexa, which is received by a laptop and placed within a visual Internet of Things/robotics programming language environment.
Based on that information and the command given, instructions are sent back to the wheelchair and to the guide dog to decide the appropriate movement.
