This robotic anthropomorphic hand uses its fingers as legs. Anthropomorphic hands are mechanical hands designed to reproduce the shape, movement, and dexterity of the human hand, typically using an articulated thumb and multiple fingers controlled by electric motors, tendons, gears, or other compact actuators.
Unlike simple two-finger robotic grippers, an anthropomorphic hand can use different grasping patterns to hold objects ranging from a heavy tool to a small coin, while a highly articulated thumb makes movements such as pinching and repositioning objects possible.
Advanced designs incorporate force, pressure, position, and tactile sensors into the fingertips and palm, giving the robot feedback about where an object is touching its hand, how tightly it is being held, and whether it is beginning to slip. AI can combine this sense of touch with cameras and proprioception—the robot’s awareness of the position of its own fingers and joints—to continuously adjust a grasp while manipulating an object.
Anthropomorphic hands are particularly important for humanoid robots because nearly everything in our homes and workplaces, from door handles and power tools to dishes and computer keyboards, was designed around the size and capabilities of human hands.
As artificial skin, tactile sensing, actuators, and dexterous manipulation improve, robotic hands could allow humanoids to use existing tools and perform delicate everyday tasks without requiring the human environment to be redesigned for robots.
