Duke University researchers have revealed an electronics-free, soft robot. It developed like a dragonfly that can react to environmental conditions such as temperature, pH, or the presence of oil and fly across the water. The proof-of-principle demonstration could be the antecedent to more autonomous, long-range, superior environmental sentinels for observing a broad range of possible telltale indications of problems. On March 25, the Advanced Intelligent Systems publication online described the soft robot. Due to the flexibility of Soft robots, they are a growing trend in the industry. Soft bodies can handle sensitive things such as living tissues that metal or ceramic elements would damage. Soft bodies can assist robots to fly or squeeze into compact spaces where rigid structures would get stuck.
