Description :

– The DFRobot 4WD Mobile Platform for Arduino is intended for use with the DFRobot ROMEO Microcontroller and includes 4x drive 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 surfaces.
– Increased life span of the electronics and gears due to the chassis study structure.
– 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.
– The motor comes with a built-in encoder which measures the motor’s speed in real time.
– The average output number of pulses can reach up to 7250 pulses per revolution.
– The motor has a long (0.354″/9.0 mm) D profile metal output shaft that is compatible with the 42x19mm and 32x7mm dimensions of the Pololu wheel.
– The brass faceplate has two mounting holes threaded for M1.6 screws (1.6mm diameter, 0.35mm thread pitch), or you can use the mounting bracket or extended mounting bracket which are specifically designed to securely mount the gear motor while enclosing the exposed gears.
– Compatible with 2WD miniQ Robot Chassis.
– The hall sensor of the new version has 7 pole pairs, so the encoder resolution will be increased by 7-fold.
