Summary
Researchers developed a single-component robot using programmable shape memory polymers. This innovation enables robots to support 3D shapes and actuate without complex assembly, paving the way for simpler robotic designs.
Area of Science:
- Robotics
- Materials Science
- Polymer Chemistry
Background:
- Traditional robots require multiple components for structural support and actuation, necessitating complex assembly.
- The development of assembly-free robots remains a significant challenge in robotics research.
Purpose of the Study:
- To devise a strategy for creating single-component robots capable of both 3D structural support and localized actuation.
- To utilize programmable crystalline shape memory polymers with reversible bonds for robot fabrication.
Main Methods:
- A plasticity-based origami technique was employed, utilizing thermo-reversible bonds to create global 3D structural support.
- Photo-reversible bonds were used to program localized, reversible shape memory for precise actuation within the 3D origami structure.
- A polymer thin film was programmed into various soft robot forms, including a 3D crane and an elephant.
Main Results:
- A novel method for fabricating single-component soft robots was successfully demonstrated.
- The developed robots exhibit independent control over 3D structural support and localized actuation.
- The strategy allows for the creation of diverse soft robot morphologies from a single material.
Conclusions:
- The proposed strategy offers a generalizable approach to constructing single-component soft robots.
- This method overcomes the limitations of traditional multi-component robot assembly.
- Future work can explore incorporating other actuation mechanisms using similar principles.

4.1K
Unlike ionic or small covalent molecules, polymers do not form crystalline solids due to the diffusion limitations of their long-chain structures. However, polymers contain microscopic crystalline domains separated by amorphous domains.
Crystalline domains are the regions where polymer chains are aligned in an orderly manner and held together in proximity by intermolecular forces. For example, chains in the crystalline domains of polyethylene and nylon are bound together by van der Waals...

41.4K
The word polymer is derived from the Greek words “poly” which means “many” and “mer” which means “parts”. Polymers are long chains of molecules composed of repeating units of smaller molecules, known as monomers. They either occur naturally, such as DNA and proteins, or can be constructed synthetically, like plastics. They have varied structural characteristics, such as linear chains, branched chains, or complex networks, that contribute to the...

Network covalent solids contain a three-dimensional network of covalently bonded atoms as found in the crystal structures of nonmetals like diamond, graphite, silicon, and some covalent compounds, such as silicon dioxide (sand) and silicon carbide (carborundum, the abrasive on sandpaper). Many minerals have networks of covalent bonds.
To break or to melt a covalent network solid, covalent bonds must be broken. Because covalent bonds are relatively strong, covalent network solids are typically...

Overview
When atoms gain or lose electrons to achieve a more stable electron configuration they form ions. Ionic bonds are electrostatic attractions between ions with opposite charges. Ionic compounds are rigid and brittle when solid and may dissociate into their constituent ions in water. Covalent compounds, by contrast, remain intact unless a chemical reaction breaks them.
Opposing Charges Hold Ions Together in Ionic Compounds
Ionic bonds are reversible electrostatic interactions between ions...
