Project actions

01Consider using 3D printing for rapid prototyping of your design.
02Think about how you can test your design's functionality in a real-world context, even if it's a simplified version.

Method & Evidence

AimTo develop and validate a framework for the rapid, iterative design of anthropomorphic soft robotic hands using 3D printing and teleoperated real-world task evaluation.

MethodIterative design and experimental validation

ProcedureThe researchers designed a 16-Degree-of-Freedom (DoF) anthropomorphic soft hand (DASH) and iteratively improved it over three design cycles. Each iteration involved 3D printing the hand, evaluating its performance in real-world manipulation tasks through teleoperation, and using the results to inform the next design iteration. The final design was compared against a commercial rigid hand (Allegro) on a set of 30 manipulation tasks.
