Abstract

A computerizable robotic automated bogie is provided including a drive motor and a main drive shaft extending downwardly from the drive motor. A rotatable plate is rotatably coupled to a bottom of a platform and further rotatable with respect to the main drive shaft. A gear mechanism is operatively coupled to the drive shaft. At least one wheel has an axis coupled with the gear mechanism thereby effecting rotation of the at least one wheel about a horizontal axis upon the actuation of the drive motor. The axis about which the at least one wheel rotates is fixed with respect to the rotatable plate. Further included is a rotating mechanism operatively engaged with the rotatable plate for selectively rotating the horizontal axis about which the at least one wheel resides.

Claims
