Baby, Kids' and Children's Products Design AirWalker Infants Walker by Satyakam Sharma AirWalker is an air-assisted walking device for infants. Four propellers, based on the quadcopter technology used in drones, provide a gentle lift equal to about half of the body weight of the child. The lift encourages the child to stand and to balance with her own muscles. AirWalker hovers but does not move forward by itself, so the child uses her legs to advance. Safety grills cover the propellers, and built-in sensors keep the device level and limit the lift to about six inches above the ground. AirWalker supports the natural learning of balance, postural control and muscle strength.
