The DFRobot 4WD mobile Platform is intended for use with the DFRobot ROMEO All-in-one Controller and includes 4x motors, 4x wheels and a complete chassis with mounting hardware. The included second level allows you to add more electronics and define a modular layout. The rectangular hole allows for a servo to be attached and be used for several purposes like a movable camera or a robotic arm. The high-strength aluminum alloy body material provides flexibility in rapid movement particularly in outdoor grass, gravel, sand or sloped surface. Increased life span of the electronics and gears due to the chasis study structure. The 4WD Arduino Mobile Platform is also suitable for robot competitions and research related projects.
A variety of sensors can be easily added and kept protected from external damage. The bottom sturdy case keeps the motors and battery pack protected to avoid fall damage. If you have built from salvaged parts before, you can tell the difference from a high-strength aluminum alloy that holds parts together and is tailored for sensors and electronic assembly.
