According to Ba, though small in size, the parking robots have a capacity to carry cargo weighing up to 3.5 metric tons. And they are environmentally-friendly -- these fully electric, zero-emission robots can work for six hours on a single charge. They also can go to the charging station to recharge themselves when the battery is low.
Built-in sensors enable the robots to automatically avoid obstacles and adjust their speed, effectively reducing the risk of dents or scratches on cars caused by parking lot mishaps.
