Compliant underactuated grasper

This invention describes a robotic gripper with two fingers, each having a flexible joint and a simple hinge to a palm base. It's 'underactuated,' meaning fewer motors control more movements, making it simpler and more adaptable for grasping. While initially described with two fingers, the design also allows for adding a thumb.

Why it matters: In 2013, fabricating precise compliant flexure joints was challenging. Advances in 3D printing materials and techniques since then make creating these complex, flexible components much more accessible and cost-effective, potentially simplifying manufacturing.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: ModerateCustom compliant parts, underactuation mechanism, sensors.
