The FW-mid is a versatile wheeled robotic mobile chassis, embodying exceptional flexibility. Its four-wheel drive (4WD) structure, with independent four-wheel drive and steering, allows for precise control of chassis steering. The independent drive provides a strong driving force, superior maneuverability, and off-road performance.

Its flexible control enables it to move laterally and on-site steering, and its excellent terrain adaptability makes it suitable for a variety of applications both indoors and outdoors. Its smooth, low-noise ride and tire-resistant design combine the advantages of both front-steering and differential systems, overcoming the steering shortcomings of four-wheel differentials.
