The Sensational Robotic Hand: Skillfully Identifying Objects by Sensing Their Shapes
Introduction:
Introducing the GelSight EndoFlex, a groundbreaking robotic hand developed by scientists at MIT. This innovative device incorporates the university’s GelSight technology, previously only used in fingertip pads, allowing the hand to sense the shape of delicate objects it’s manipulating. The GelSight EndoFlex features three mechanical digits arranged in a Y shape, with GelSight sensors located on the underside of each digit. These sensors use clear synthetic rubber and a layer of metallic paint to capture 3D images of the object’s surface. By combining images from six sensors, the hand can create a three-dimensional model and accurately identify the object. With further development, this technology could revolutionize robotic manipulation tasks. Source: MIT

Robot Hand Uses GelSight Technology to Identify Objects
A team of scientists at MIT has developed a robotic hand that can identify different objects based on their shape. This innovative device, called the GelSight EndoFlex, incorporates GelSight technology, which was previously used only in the fingertip pads of robotic hands.
Design and Functionality of the GelSight EndoFlex
The GelSight EndoFlex features three mechanical digits arranged in a Y shape. It consists of two fingers at the top and an opposable thumb at the bottom. Each digit comprises an articulated hard polymer skeleton enclosed within a soft and flexible outer layer. The GelSight sensors, two per digit, are located underneath the top and middle sections.
How GelSight Sensors Work
The GelSight sensors consist of a clear, synthetic rubber slab coated with a layer of metallic paint. The paint acts as the finger’s skin and deforms when pressed against a surface. A tiny integrated camera, along with three colored LEDs, captures the minute contours of the surface by looking through the unpainted side of the rubber. These contours are then converted into 3D images by special algorithms on a connected computer.
Creating a 3D Model and Object Identification
By combining images from six GelSight sensors (two on each digit), the GelSight EndoFlex can create a three-dimensional model of the grasped object. Machine-learning-based software then analyzes the model to identify the object. Notably, the system achieves an accuracy rate of approximately 85% in its current form, with potential for improvement as the technology advances.
Advancements in Robotic Manipulation
Mechanical engineering graduate student Sandra Liu, who co-led the research with undergraduate student Leonardo Zamora Yañez and Prof. Edward Adelson, emphasized the importance of incorporating both soft and rigid elements in robotic hands. The ability to perform extensive sensing over a large area is crucial, especially for complex manipulation tasks. The GelSight EndoFlex aims to replicate the capabilities of human hands and perform tasks that other robotic fingers cannot currently accomplish.
Conclusion
The GelSight EndoFlex, developed by MIT scientists, showcases the potential for robotic hands to handle delicate objects effectively. By incorporating GelSight technology into the design, the hand can sense and identify objects based on their shape. This advancement could lead to significant developments in robotic manipulation and pave the way for more sophisticated robotic hands in the future.
