ONLINE COVER Malleable Machines. Advances in materials science often improve machines as well. Terryn et al. construct their robotics using self-healing polymers that exploit Diels-Alders reactions. They demonstrate a soft gripper, a soft hand, and artificial muscles that can be healed with mild heat treatment. The polymers also have the advantage of being recyclable. [CREDIT: SEPPE TERRYN]
