We design a vehicle with a steering system made of two independentlyrotatable wheels on the front. We quantify the effectiveness of the steeringsystem in the mobility and maneuverability of the vehicle running in a boxcontaining a layer ping-pong balls with a packing density 0.8, below the randomclose packing value 0.84 in 2D. The steering system can reduce the resistanceexerted by the jammed balls formed ahead of the fast-moving vehicle. Moreover,if only one of the two steering wheels rotates, the vehicle can turn into thedirection opposite to the rotating wheel. The steering system performs moreefficiently if the wheels engage the ping-pong balls better by increasing thecontact area between the wheels and the balls. We advocate applying our designto machines moving in granular materials with a moderate packing density.
