Robot hand moves closer to human abilities
Posted by Dan Kummer in category: robotics/AI
A team of researchers affiliated with multiple institutions in Korea has developed a robot hand that has abilities similar to human hands. In their paper published in the journal Nature Communications, the group describes how they achieved a high level of dexterity while keeping the hand’s size and weight low enough to attach to a robot arm.
Creating robot hands with the dexterity, strength and flexibility of human hands is a challenging task for engineers—typically, some attributes are discarded to allow for others. In this new effort, the researchers developed a new robot hand based on a linkage-driven mechanism that allows it to articulate similarly to the human hand. They began their work by conducting a survey of existing robot hands and assessing their strengths and weaknesses. They then drew up a list of features they believed their hand should have, such as fingertip force, a high degree of controllability, low cost and high dexterity.
