For this reason, the weight distribution will not affect a variety of characteristics of the robot, including handling, traction, and acceleration. The apportion of weight in the front and the back of the chassis is equal. The weight distribution was a crucial factor in the design decisions of the structure of the chassis. Also, the 3D printed parts allow me to play with different designs to produce the ultimate 4WD robot chassis.
But as an engineer, I start from a specific set of requirements to build a platform capable of hosting different sensors, microcontrollers, and computers. There are many possible designs for such a platform. The platform works well, but it is limited in terms of space and capabilities.Ī 4WD chassis is easy to design, easy to build, robust, and we have many options to attach different components and parts. Several weeks ago, I built an obstacle avoiding robot on a 2WD plastic platform. In this tutorial, we will learn how to build a 4WD robot chassis using aluminum profiles and 3D printed parts.
