Abstract
A child motion device includes a frame providing a structural support relative to a reference surface and including an arm pivotably coupled to the structural support for reciprocating movement with a resonant frequency, a child supporting device coupled to the arm and spaced from the reference surface by the frame, and a drive system including a motor configured to drive the arm such that the child supporting device reciprocates along a motion path at a frequency matched to the resonant frequency. The drive system is configured to adjust a duty cycle of the motor to control a speed at which the child support device moves along the motion path.
