PROJECT TOPICResearch Frontiers & Advanced Kinematics
Origami Metamaterial Adaptive Gripper
A compliant metamaterials concept investigating crease-patterned origami folding structures driven by a single linear tendon to conformally envelop irregularly shaped, delicate, or unknown objects.
Underactuated Mechanical Intelligence
- ✓Grasps delicate, irregular objects securely using a single motor and no electronic sensors.
- ✓Distributes gripping pressure uniformly across surfaces through mechanical origami compliance.
- ✓Fabricated as a single monolithic folding sheet, eliminating pins, bearings, and assembly labor.
The Engineering Challenge
Problem / Objective
Multi-fingered robotic hands require dozens of motors, complex joint sensors, and complicated control algorithms to grasp fragile organic items.
