The invention relates to a carriage cart (100), which comprises a chassis frame (110) with a front end (112) and a rear end (114); a pair of front wheels (130) mounted on the front end (112) of the chassis frame (110); a pair of rear wheels (130) mounted on the rear end (114) of the chassis frame (110); wherein each wheel (120,130) comprises a lifting member (140,170) pivotally mounted on a pivot (150,180) at the same side of the chassis frame (110) with the wheel (120,130), wherein when the carriage cart (100) is moving in a travel direction (10) running from the rear end (114) to the front end (112) of the chassis frame (110) on a first surface (200) by rotation of the wheel in a first rotation direction, the lifting member (140) of the front wheel (120) is projected beyond the front wheel (120) in the travel direction, and wherein as the carriage cart (100) is negotiating a second surface (300) substantially perpendicular to the first surface (200), the lifting member (140) of the front wheel (120) contacts firstly the second surface (300), by which the lifting member (140) is pivoted in a second rotation direction opposite to the first rotation direction, thereby lifting the front wheel (120) off the first surface (200). The carriage cart (100) according to example embodiments of the present invention may improve the performance of obstacle overcoming for robotic system.
