Product Information

The chassis frame is designed to house four geared DC motors with wheels and the ability to drive around with heavy loads. The aluminum profiles provide slots on every side of the chassis frame to assemble the drive system, sensors, microcontrollers and computers, and other components. The controller accepts analog, RC, and TTL serial input. For testing the chassis, it used the remote control method. 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. 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.

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

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. void setup() { Serial.begin (9600); pinMode(trigPin, OUTPUT); pinMode(echoPin, INPUT); // pinMode(led, OUTPUT);// // pinMode(led2, OUTPUT);// pinMode(pinI1,OUTPUT); pinMode(pinI2,OUTPUT); pinMode(speedpinA,OUTPUT); pinMode(pinI3,OUTPUT); pinMode(pinI4,OUTPUT); pinMode(speedpinB,OUTPUT); } The connection between the RC receiver and the Sabertooth is simple. The motor driver has four screw terminals: GND, 5V, S1, and S2.For controlling the DC motors of the chassis with an RC receiver, the RC mode of the driver must be taken into consideration. The RC input uses two channels from the receiver to set the speed and direction of the motors. To set up the driver’s RC mode, we have to choose the DIP switch for Mode 2. The DIP switch has pins 1 and 3 OFF, while the others ON for linear control of the DC motors. 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 driver provides the current to the DC motors at the required voltage but cannot decide how the motors should run.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. 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.
