Detachable Robot That Moves the Baby Bouncer

A baby bouncer is a type of cradle that allows for rocking and soothing through the baby’s own movements or the use of hands by an adult. An electric baby bouncer is designed to automatically rock the baby, enabling parents to soothe their child without using their hands and reducing the effort required. However, existing electric baby bouncers have the drawback of being expensive, heavy, and bulky. In this study, we propose an external attachment device that can be easily added to existing manual baby bouncers to enable automatic rocking. This device operates by transmitting the rotation of a servo motor to the baby bouncer, facilitating the rocking motion. Through experimentation, we validated that the device can adapt to variations in the baby’s weight and changes in the servo motor’s rotation cycle, thereby allowing for adjustments in the swing range of the baby bouncer.
