Abstract
In one aspect, provided is a robotic hand, comprising a plurality of robotic fingers; and a robotic palm, configured to operatively connect with the plurality of robotic fingers, wherein individual robotic finger comprises: a first phalanx; a second phalanx; and a first hydraulic actuator, configured to operatively connect the first phalanx with the second phalanx, wherein the first hydraulic actuator comprises a soft, bellows-type deformable body, such that when in operation, the first hydraulic actuator is switchable between at least a compression status and an extension status, in response to external force and/or hydraulic pressure applied thereto. Other example embodiments are described herein. In certain embodiments, the disclosure provides robotic hands and systems that showed high degrees of compliance, adaptability, and precise control for robotic applications and addressed the challenge of achieving robotic fine in-hand manipulation.
