Product Information

In the first part of this tutorial, we’ll learn how to assemble the chassis using aluminum profiles and profile connectors. But before going into the assembly of the frame, let us first discuss the materials, chassis weight, and the need of precision. We carry a basic stainless steel sumo blade that can be mounted to front of the Zumo chassis. With this blade, the Zumo chassis can push around objects, such as other MiniSumo robots. You can also use the design file for this basic blade as the starting point for a custom sumo blade. The iron profiles are a bad option due to weight limitations. A chassis of a robot will carry the DC motors, batteries, electronics, mounting supports, and more. All of these components and parts are added to the weight of the chassis itself, which will count towards the total carrying capacity of the electrical motors. So, we have to keep the weight as low as possible. 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. Fully assembled, the Zumo chassis is 98mm wide, 86mm long, and 39mm high, with approximately 5mm of ground clearance.

Since each side is smaller than 10cm, this chassis meets Mini-Sumo size requirements. The front screws used to mount the acrylic plate to the chassis can also be used to mount a front scoop that can extend up to 14mm before exceeding the Mini Sumo limits. The assembled Zumo chassis weighs approximately 210g with motors and batteries. 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. 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. Several weeks ago, I built an obstacle avoiding robot on a 2WD plastic platform. The platform works well, but it is limited in terms of space and capabilities.

The aluminum profiles have the best strength/weight ratio for a robot. Furthermore, it has excellent corrosion resistance and the ability to connect with precision the profiles during their installation.

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. 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. pinMode(pinI1,OUTPUT); pinMode(pinI2,OUTPUT); pinMode(speedpinA,OUTPUT); pinMode(pinI3,OUTPUT); pinMode(pinI4,OUTPUT); pinMode(speedpinB,OUTPUT); }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.

void setup() { Serial.begin (9600); pinMode(trigPin, OUTPUT); pinMode(echoPin, INPUT); // pinMode(led, OUTPUT);// // pinMode(led2, OUTPUT);// If your goal is to make a robot based around a controller other than an Arduino, we recommend the DRV8833 motor driver carrier or qik 2s9v1 for use with this chassis.If we want to build a robot that will go straight, you need all the frame parts and the components to be perfectly symmetric with the chassis. 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). What tools will I need? A complete list of tools that will be useful for the construction of the robot. Once the chassis is assembled and all the profiles are aligned, we can attach components to this frame. 2. How to build the drive system 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.
