'DeployBot' is the First Walking, Soft Robot to Use No Motors
Researchers from Seoul National University have built the first robot made of soft, deployable materials that can move itself without the use of motors or any additional mechanical components. The robot 'walks' when an electric current is applied to shape-memory alloy wires embedded in its frame. The current heats the wires, causing the robot's flexible segments to contract and bend; controlling the current to various segments in different ways results in different walking gaits. The robot's ability to be easily deployed, along with its low cost, compact size, and ability to be reconfigured into different forms may make it useful for applications from space missions to ocean exploration.
