Product Information

A 4WD chassis is easy to design, easy to build, robust, and we have many options to attach different components and parts. Assembly of the Chassis: The chassis kit comes with paper instructions that are quite good. The pictures are designed to be supplemental to the paper instructions. 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 driver provides the current to the DC motors at the required voltage but cannot decide how the motors should run.This chassis works with four AA batteries. We recommend using rechargeable AA NiMH cells, which results in a nominal voltage of 4.8V (1.2V per cell). When the batteries are fully charged, they will be well above 5V, and when they are almost spent, they will be well below 5V. As such, you might consider using a step-up/step-down voltage regulator to power your logic, since this will hold your logic voltage steady at 5 V, no matter if your battery voltage is above or below 5V. You can also use alkaline cells, which would nominally give you 6V, but that voltage would drop depending on the load. Basic sumo blade (not included) The chassis has four DC geared motors and four wheels connected directly to the motors. The architecture of the chassis includes 3D printed parts for the DC motors and wheels. The 3D printed components can be changed to matching something like encoders and additional accessories.

Tracked Robot Chassis

Before designing the chassis frame, I have sorted out all the DC motors, wheels, and the battery to power the robot. All of these are put together in a chassis frame of 19cm wide by 29cm long by 10cm high. The objective of the testing is to evaluate the technical features and study the performance of the platform. We choose to use a receiver and remote control to test the platform because it is simple and easy to implement. The DC motors are controlled by a Sabertooth dual 25A 6V-30V regenerative motor driver. This motor driver is compatible with a microcontroller like Arduino and with a Linux computer like Raspberry Pi. If your robot application demands real-time responses, you need to use a microcontroller board such as Arduino. The Raspberry Pi board is based on an ARM-Cortex processor, which is more powerful than Arduino and capable of running ROS.There are many possible designs for such a platform. But as an engineer, I start from a specific set of requirements to build a platform capable of hosting different sensors, microcontrollers, and computers. Also, the 3D printed parts allow me to play with different designs to produce the ultimate 4WD robot chassis.
