Product Information

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. You can add your own motor drivers, sensors, and programmable controllers to this chassis, or you can get one of our more complete Zumo robots, which include electronics designed specifically for the Zumo chassis. 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 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.

Add sensors, an Arduino board and a Raspberry Pi board to detect obstacles and communicate wireless with the robot; Resources: A 4WD chassis is easy to design, easy to build, robust, and we have many options to attach different components and parts. The controller accepts analog, RC, and TTL serial input. For testing the chassis, it used the remote control method.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.

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. 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. 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. 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) 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.

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.
