A golf bag transport device that is configured to assist in the transportation of a golf bag for a user during a round of play of golf. The present invention includes a base platform wherein the base platform includes drive wheels on opposing sides thereof. The base platform has a vertical golf bag support member extending upward therefrom. The vertical golf bag support member is further constructed to be collapsible. Secured to the vertical golf bag support member are horizontal support members configured to assist in retention of a golf bag. Opposing auxiliary wheels are located proximate the front edge and rear edge of the base platform. The auxiliary wheels are configured to assist in maintenance of the position of the base platform while traversing a sloped surface. Optical sensors are employed to provide collision avoidance and a gyroscopic balancing unit provides self-balancing of the device during use.
