How do the new soft robots move without traditional motors?

The soft robots move and shape-shift through external electric fields, which induce stretching, bending, and twisting motions in the electro-morphing gel material.

What is the electro-morphing gel robot made from?

The robot is constructed from a smart composite called electro-morphing gel (e-MG) and utilizes ultra-lightweight electrodes.

What are the potential applications for these shape-shifting robots?

Potential applications include healthcare for minimally invasive procedures, environmental exploration in fragile or tight spaces, and search-and-rescue in confined areas.

Shape-Shifting Gel Robot No Motor Needed

Researchers have engineered a novel soft robot from electro-morphing gel that moves and shape-shifts through external electric fields, negating the requirement for conventional motors, gears, or rigid joints. This advancement enables navigation in previously inaccessible areas. The robot utilizes ultra-lightweight electrodes that rapidly respond to electric fields, inducing stretching, bending, and twisting motions.

A miniature humanoid gymnast, crafted from this smart composite, has demonstrated its ability to swing across surfaces by manipulating external electric fields. Testing revealed consistent performance over 10,000 actuation cycles. Researchers envision these adaptable robots as "Swiss Army knives" for specialized tasks.

Potential applications span diverse fields, including minimally invasive healthcare procedures, environmental exploration in fragile or tight spaces, and search-and-rescue operations in confined environments where traditional machines cannot operate.
