For testing the chassis, it used the remote control method. In this tutorial, we will learn how to build a 4WD robot chassis using aluminum profiles and 3D printed parts. For this chassis, the differential drive movement is used based on four separately driven wheels placed on either side of the robot body. In this case, we have to connect two DC motors from one side of the chassis to one channel of the motor drive, and the other two DC motors to the second channel. The terminals M1A-M1B and M2A-M2B are used for connecting the electric motors to the motor driver. int pinI1=8;//define I1 interface int pinI2=11;//define I2 interface int speedpinA=9;//enable motor A int pinI3=12;//define I3 interface int pinI4=13;//define I4 interface int speedpinB=10;//enable motor B

Tracked Robot Chassis

In this part of the article, we’ll learn the drive system architecture, including the components, assembly, and the 3D printed parts.

The driver provides the current to the DC motors at the required voltage but cannot decide how the motors should run. In the last few years, I have examined different options to build chassis frames, including Perspex, Plexiglas, L shape aluminum profiles, and mild square iron profiles (for a heavy-duty robot). However, I have excluded Perspex and Plexiglas because these materials tend to shatter if bent. The Sabertooth 2 X 25A motor driver has two channels to control at least two DC motors on each pipe. The chassis is running on four DC motors, so we have to connect all these to two channels. The Zumo Robot for Arduino combines a Zumo chassis with a Zumo shield, which includes a dual motor driver, buzzer, and three-axis accelerometer and compass, giving you all the basic mechanical parts and electronics to build an Arduino-controllable robot (Arduino not included). The newer Zumo 32U4 Robot is a more highly integrated robot also based on the Zumo chassis that includes an Arduino-compatible ATmega32U4 microcontroller and even more sensors (quadrature encoders and a proximity sensor system). Programs in the Arduino language are called sketches. Load this sample sketch and your robot will be zooming around in no time! If you have problems with the .ino file, the program is included below in bold, just copy and paste into the Arduino executable window.

But before going into the assembly of the frame, let us first discuss the materials, chassis weight, and the need of precision.What tools will I need? A complete list of tools that will be useful for the construction of the robot.
