1. An infant care apparatus comprising: a base;a drive mechanism coupled to the base, the drive mechanism comprising a horizontal reciprocating assembly comprising a sliding stage; and a vertical reciprocating assembly disposed on an upper surface of the sliding stage of the horizontal reciprocating assembly;a controller electronically coupled to the drive mechanism;a support device coupled to the drive mechanism, the support device configured to be moved in both a horizontal direction relative to the base by the horizontal reciprocating assembly and a vertical direction relative to the base by the vertical reciprocating assembly; anda dual scissor mechanism positioned between the support device and the sliding stage, the dual scissor mechanism configured to support the support device,wherein the drive mechanism is controlled by the controller wherein the controller is configured to move the support device in a plurality of visually distinctive motion profiles relative to the base that are obtained by independently controlling, by the controller, horizontal movement provided by the horizontal reciprocating assembly and vertical movement provided by the vertical reciprocating assembly and then coordinating, by the controller, the horizontal and vertical movements to obtain the plurality of visually distinctive motion profiles. 2. The infant care apparatus of claim 1, wherein the controller is mounted within the base. 3. The infant care apparatus of claim 2, wherein the controller includes a user interface configured to receive input from the user for controlling the movement of the drive mechanism. 4. The infant care apparatus of claim 1, wherein the horizontal reciprocating assembly comprises: a first motor having a drive shaft;a slide crank assembly comprising a gearing assembly coupled to the drive shaft of the first motor and a crank member coupled to the gearing assembly; andthe sliding stage coupled to the crank member,wherein operation of the first motor causes rotation of the slide crank assembly, thereby imparting reciprocating horizontal motion to the sliding stage. 5. The infant care apparatus of claim 1, wherein the vertical reciprocating assembly comprises: a second motor having a drive shaft;a worm gear assembly coupled to an output of the drive shaft; anda vertical yoke having a first end coupled to an output shaft of the worm gear assembly,wherein operation of the second motor causes rotation of the vertical yoke, thereby imparting reciprocating vertical motion to the support device. 6. The infant care apparatus of claim 1, further comprising a first motor for providing horizontal motion to the support device and a second motor for providing vertical motion to the support device. 7. The infant care apparatus of claim 6, wherein a first encoder having a single slot is coupled to a drive shaft of the first motor and a second encoder having a single slot is coupled to the drive shaft of the second motor. 8. The infant care apparatus of claim 7, wherein the controller determines position information of the support device based at least in part on information from the first encoder and the second encoder. 9. The infant care apparatus of claim 1, wherein the support device comprises: a seat support tube coupled to the drive mechanism;a substantially elliptical seating portion coupled to a first end and a second end of the seat support tube; anda toy bar having a first end coupled to the second end of the seat support tube and a second end extending over the seating portion. 10. The infant care apparatus of claim 9, wherein the position of the seating portion of the support device is adjustable by sliding the seat support tube within the drive mechanism and locking the seat support tube in a desired position. 11. The infant care apparatus of claim 9, wherein the first end of the toy bar includes a curved surface that corresponds to a curved surface of the second end of the seat support tube, thereby causing the second end of the toy bar to be centered over the seating portion when the first end of the toy bar is coupled to the second end of the seat support tube. 12. An infant care apparatus comprising: a base;a drive mechanism coupled to the base, the drive mechanism comprising a horizontal reciprocating assembly comprising a sliding stage; and a vertical reciprocating assembly disposed on an upper surface of the sliding stage of the horizontal reciprocating assembly;a controller electronically coupled to the drive mechanism;a support device coupled to the drive mechanism, the support device configured to be moved in both a horizontal and vertical direction relative to the base by the drive mechanism; anda dual scissor mechanism positioned between the support device and the sliding stage, the dual scissor mechanism configured to support the support device,wherein the controller is configured to independently control, by the controller, horizontal movement provided by the horizontal reciprocating assembly and vertical movement provided by the vertical reciprocating assembly, and wherein movement of the support device in the horizontal and vertical directions is independently controlled by the controller and then the movement of the support device in the horizontal and vertical directions is coordinated by the controller to obtain a plurality of visually, distinctive motion profiles. 13. The infant care apparatus of claim 12, wherein movement of the support device in the horizontal and vertical directions is coordinated to obtain at least one motion profile. 14. The infant care apparatus of claim 12, wherein the support device is moved in the vertical direction a maximum of about 1.5 inches and the support device is moved in the horizontal direction a maximum of about 3.0 inches. 15.
