Machines

Machines are complex structures consisting of movable, pin-connected multi-force members that work together to transmit forces. One example of a machine is the cutting plier, which is used to cut wires by applying forces to its handles. When equal and opposite forces are exerted on the handles of the cutting plier, they cause the cutting edges to come together and apply equal and opposite reaction forces on the wire, which are greater than the applied forces.

Background:

Biological systems demonstrate remarkable adaptation through morphology changes like self-amputation and collective behaviors.
Concepts of morphological editing in nature inspire advancements in modular robotics for adaptable structures.

Purpose of the Study:

To develop a reversible cohesive interface for soft robot modules, enabling easy attachment and detachment without human intervention.
To integrate this interface into soft robots for dynamic shape-shifting capabilities, mimicking biological autotomy and fusion.

Main Methods:

Fabrication of a reversible cohesive interface using thermoplastic elastomer with properties compatible with soft robotics.
Implementation of the interface in a soft quadruped robot for self-amputation and in a cluster of soft robots for fusion-based locomotion.

Main Results:

The developed interface provides strong attachment and easy detachment, crucial for modular soft robots.
Demonstrated self-amputation in a quadruped robot when encountering obstacles and collective fusion for traversing gaps by crawling robots.

Conclusions:

The reversible cohesive interface enables soft robots to dynamically alter their morphology through autotomy and interfusion.
This technology paves the way for future robots with radical shape-shifting abilities and highlights the importance of interfacial properties in adaptable systems.
