A Vision for the Future: Baxter Shines in Research to Guide the Blind

Researchers at Carnegie Mellon University's TechBridgeWorld Group Use Collaborative Robot Technology to Enhance Navigation in Urban Settings

BOSTON, Aug. 25, 2015 -- For the world's 285 million people living blind or visually impaired, Rethink Robotics' Baxter Research Robot can provide an avenue to a more accessible future. Researchers at Carnegie Mellon University's TechBridgeWorld are using Baxter to explore how technology - and specifically, robots - can help the blind and visually impaired more effectively navigate urban environments.


For people with sight, the necessary tasks associated with urban living - crossing the street, sorting bus tickets or finding the right storefront - are accomplished without a second thought. Innovations using collaborative robotics can make these tasks just as easy for the blind population.

"There are examples of technology causing divides in society, but it also has the potential to build bridges and serve communities, especially people who must alter behaviors due to disabilities," said M. Bernardine Dias, founder and director of the TechBridgeWorld research group in CMU's Robotics Institute. "We're committed to help people overcome physical challenges by using the Baxter Research Robot to explore different real-life scenarios, and we've made great strides in helping the blind achieve greater levels of independence and empowerment."

CMU researchers are experimenting with Baxter for several applications, with visions of a smart city future in mind. For example, to assist blind travelers Baxter is being used to provide vocal directions reinforced with physical directional gestures on the traveler's hand. The robot can also help users select the correct bus ticket, a task that can be difficult when tickets to different destinations are physically identical in every way except for text and color. The research team is also making great inroads into multi-robot skill coordination, a scenario in which Baxter communicates with mobile robots to help guide travelers along their journeys.

"Collaborative robots like Baxter can effectively interact with humans in factories, but in the unstructured and variable urban environments that are home to millions of blind people, the complexity skyrockets," said Scott Eckert, president and CEO of Rethink Robotics. "Thanks to Baxter's open source platform, human-like form and ability to interact directly with humans, the research team at Carnegie Mellon is helping to drive social change and improve the lives of millions."

ST Robotics Develops the Workspace Sentry for Collaborative Robotics

The ST Robotics Workspace Sentry robot and area safety system are based on a small module that sends an infrared beam across the workspace. If the user puts his hand (or any other object) in the workspace, the robot stops using programmable emergency deceleration. Each module has three beams at different angles and the distance a beam reaches is adjustable. Two or more modules can be daisy chained to watch a wider area. "A robot that is tuned to stop on impact may not be safe. Robots where the trip torque can be set at low thresholds are too slow for any practical industrial application. The best system is where the work area has proximity detectors so the robot stops before impact and that is the approach ST Robotics has taken," states President and CEO of ST Robotics David Sands.
