ONLINE COVER From the Tip Leveraging the flexibility that is possible when using soft materials, Hawkes et al. used pneumatics to extend the tip of a robot over an extended distance. They inflated chambers on only one side of the robot to make it turn. An onboard camera connected to a feedback loop allowed the robot to track toward a distant light source. [CREDIT: LINDA A.
