Supernumerary robotic limbs are robotic devices providing additional limbs to the user. Mattia Pinardi and colleagues review the impact of supplementary sensory feedback on the control performance and embodiment of supernumerary robotic limbs.
Ahmed Othman and colleagues review flow control strategies used by birds, insects and aquatic animals, and how they have been adopted in engineered devices. The focus on passive and local flow control is of particular relevance to the design of small uncrewed aerial and aquatic vehicles.
