Abstract
Various embodiments of the present invention are directed to a powered children's swing. In various embodiments, the swing includes a seat, swing frame, one or more swing arms, a first magnetic component, second magnetic component, swing motion sensor, and swing control circuit. The magnetic components are configured to generate a magnetic force that drives the seat along a swing path. The swing control circuit is configured to control the magnetic components based at least on input from the swing motion sensor and generate control signals causing the seat to swing with a substantially constant amplitude as specified by a user.
