Wheeled quadruped robots combine the speed and efficiency of wheels with the ability of robotic legs to handle rough terrain, giving them an advantage over robots that only walk or only roll.
Instead of conventional feet, these robots have powered wheels at the ends of their four articulated legs. On smooth surfaces it can roll efficiently, but when it encounters stairs, rocks, steep slopes, or obstacles, its motorized joints reposition the wheels and body to climb or maintain balance.
In the future, this combination of wheels, legs, sensors, and embodied AI could make wheeled quadrupeds particularly useful for industrial inspections, carrying equipment, warehouse and outdoor logistics, agriculture, disaster response, and exploring places too hazardous for people. Rather than choosing between the efficiency of a wheeled robot and the versatility of a walking robot, these machines demonstrate how future robots could increasingly have both capabilities in the same body.
