Product Introduction

The 4WD shock-absorbing chassis  is equipped with a 2mm integrated stamping bottom plate. The surface is aluminum sprayed and treated. There are two pieces, with regularly distributed aperture of 3mm installation holes on the bottom plate, with a horizontal spacing of 12mm and a vertical spacing of 14mm, making it convenient for users to expand various sensors or make other mechanical modifications, such as installing a robotic arm. The upper plate has reserved installation holes for the Arduino platform and Raspberry Pi platform. There is also a baffle on the side that can hold batteries, etc. Its shock-absorbing part uses 4 metal shock absorbers, which gives the car better road passing ability and improves the car's off-road performance, especially on complex terrain. The car wheels are 97MM rubber wheels. Its motor is JGA25-370 (1:34 reduction ratio) motor.

This is a differential drive chassis, which means that the turning is achieved by driving the motors on both sides of the platform at different speeds. The two motors on both sides of the car are in parallel, so only two motor control channels are needed to move the chassis. It is also possible to control the six motors individually, with the working voltage of the motors being 6-12V.
