OMRON SINIC X Corporation researchers developed the SCU-Hand, a soft conical universal robotic hand that reconfigures its size to efficiently scoop granular media from variously sized containers. This end-effector achieved over 95% scooping efficiency in a single operation across a range of container diameters and granular materials, without relying on complex sensors or control.
Key insights
- Utilizing a developable conical surface from a single flexible sheet enables effective size reconfiguration and inherent powder containment without gaps, reducing complexity.
- The anisotropic stiffness of the conical structure allows the end-effector to passively conform to container surfaces while maintaining sufficient rigidity for scooping, minimizing the need for complex sensing.
- Matching the end-effector's reconfigured size to the specific container diameter is critical for maximizing scooping efficiency and minimizing spillage.
