MIT robot uses radio waves to find and retrieve hidden objects

preview

This article was published on April 1, 2021MIT researchers have developed a robot that can detect and grab objects that are hidden behind walls or pieces of clutter.The system, called RF-Grasp, uses radio waves to locate items beyond the line-of-sight of a robot’s cameras. It could help warehouse robots grab customer&nbsp;orders or&nbsp;tools&nbsp;that are occluded behind obstacles.Existing mechanical search systems struggle with these tasks due to the constraints of their sensors. If an object is concealed, they typically need to explore the environment and search for the item.Subscribe to our newsletter now for a weekly recap of our favorite AI stories in your inbox.Unlike visible light and infrared,&nbsp;RF (radio&nbsp;frequency) signals can traverse cardboard boxes, wooden walls, plastic covers, and colored glass to perceive objects fitted with RFID tags.[Read:&nbsp;]“Researchers have been giving robots human-like perception,” said study co-author Fadel Adib. “We’re trying to give robots superhuman perception.”RF-Grasp is comprised of a camera on the robot’s wrist and a separate RF reader.&nbsp;Together, they collect tracking data and create a visual map of the environment.The system first pings the object’s RF tag to identify its location. It then determines the optimal path around the obstacles to reach the item.As the robot gets closer to the object and starts manipulating it, computer vision provides more precise directions.In tests, RF-Grasp successfully identified and moved objects that were concealed behind packaging and other obstacles. The researchers say the system completed the tasks with about half as much movement as similar robots equipped with only a camera.The system does depend on target objects being tagged with RFIDs. But the widespread adoption of these chips as barcode replacements in retail, manufacturing, and warehousing means RF-Grasp could already have a practical impact.You can read the study paper .Greetings Humanoids!

The Next Web (TNW) is a website and annual series of conferences focused on new technology and start-up companies in Europe. The Next Web company was established in 2006 by co-founders Boris Veldhuijzen van Zanten and Patrick de Laive in Amsterdam, Netherlands, and a technology news website of the same name was started in 2009. On 5 March 2019, the Financial Times purchased a majority stake in TNW.
