A method and apparatus are provided for smoothing the transition in rolling element/cam type nested speed converters and as motorized in a compact pancake package. More specifically, the apparatus for translating motion from a first to a second velocity includes drive devices made up of a conjugate pair of devices and a motion translating device mounted about a common axis. The pair of conjugate devices includes a first cam and a second cam. Each of the cams has at least one flank, the flank having a main drive segment formed according to a first function and at least one transition segment formed according to a second function. In one embodiment, the motion translating device, which is radially nested in between the two cams, has a plurality of radially extending slots, each slot containing one of a plurality of elements. The element is capable of traveling radially within its respective slot.
