Universal Metamorphic Robot Hand Design
Reconfigurable five-finger hand morphs size, handedness, and grasp modes for versatile robotic/prosthetic use.
Researchers at Purdue University have designed a universal metamorphic robot hand with a five-finger device. Conventional robotic hands, notably of the metamorphic or prosthetic type, are typically configured for use in a single size or orientation. However, this poses challenges as certain applications require different types of robotic hands, which can increase costs and decrease versatility. Therefore, a robotic hand that can be deployed in various use scenarios with different sizes and orientations is direly needed.
The robotic hand developed by Purdue University researchers provides the industrial, medical, and service sectors with a dexterous and universal prosthesis hand. By controlling rotary and prismatic joints, the palm structure can be scaled and deformed to certain configurations, allowing the fingers to achieve a bi-directional grasping capability. Moreover, this design can function as either a left or right hand of variable size and shape. The robotic hand can be tailored to accommodate diverse needs and tasks, rendering this technology incredibly versatile and widely applicable.
