The ROB-BLS is R.O.B.'s first kart in Mario Kart DS. It is a round, hollow kart with five round holes and a block on each, resembling the trays and blocks used by the actual R.O.B. accessory to play Stack-Up. It has average acceleration, low drift and items, and great speed, weight, and handling. It, along with the Hurricane, has the highest top speed in the game. The kart has the same handling as the Streamliner.
The kart, alongside R.O.B. himself and the ROB-LGS, differs between regions. In Japanese versions of the game, the kart is white and red, as opposed to being all around a darker shade of grey, which is made to highlight R.O.B.'s regional differences.
