YFROBOT KIT CHASSIS METALLIQUE 4WD ROUE 72MM AVEC MOTEURS

The steering mechanism of the servo steering car chassis is different from that of a typical chassis. It uses a rear-wheel motor drive with a front steering mechanism to achieve the car’s forward, backward, and left and right turns, while a chassis without a steering structure usually uses a left-right differential steering structure. Similar to professional remote control racing car principles, the steering part uses two pull rods connected to the servo to control the car’s left and right turns. It has only one motor and an integral die-cast aluminum fixing piece that tightly engages the motor with the transmission shaft. The transmission shaft has two flanged bearings to ensure that the motor rotates more flexibly. There are two acrylic plates on top that can be used to fix accessories such as the main board, motor drive, and battery.
