Development using 3D printing and equipped with haptic sensors could bring humanity closer to integrating robots into society, as well as helping robots interact better with humans and objects.
Researchers at the University of Cambridge have developed a groundbreaking robotic arm that works with minimal fingers and can grasp objects.
The hand is 3D printed and has tactile sensors embedded in its skin. With passive wrist movement and sensors, the hand can perform complex movements with more natural and adaptive activity, paving the way for low-cost, energy-efficient robots.
Grasping objects of different sizes, shapes and textures is a huge challenge for robots, but Cambridge researchers overcame this problem by focusing on passive motion.
The robotic anthropomorphic hand is equipped with tactile sensors to determine what it is touching. Researchers conducted more than 1,200 tests to assess the hand’s ability to grasp objects without falling. Originally trained with 3D-printed plastic balls, the hand successfully held 11 of 14 different objects, including peaches, a computer mouse, and a bagel.
First study author Dr Kieran Gilday explained in a press release: “Tactile sensors give the robot an idea of how well it is holding an object so the robot knows when it starts to slip. This helps it predict when an object is at risk from falling out of hand. “
Future developments may include integrating computer vision capabilities and teaching the robot to use its environment to grasp even more objects. The team is currently working to improve the robotic arm’s accuracy and speed and explore new applications for the technology.
