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. pinMode(pinI1,OUTPUT); pinMode(pinI2,OUTPUT); pinMode(speedpinA,OUTPUT); pinMode(pinI3,OUTPUT); pinMode(pinI4,OUTPUT); pinMode(speedpinB,OUTPUT); } Add sensors, an Arduino board and a Raspberry Pi board to detect obstacles and communicate wireless with the robot; Resources:

Tracked Robot Chassis

Fully assembled, the Zumo chassis is 98mm wide, 86mm long, and 39mm high, with approximately 5mm of ground clearance.The connection between the RC receiver and the Sabertooth is simple. The motor driver has four screw terminals: GND, 5V, S1, and S2. 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.

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. 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. 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.

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. What tools will I need? A complete list of tools that will be useful for the construction of the robot. 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. 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. In this part of the article, we’ll learn the drive system architecture, including the components, assembly, and the 3D printed parts.

In this tutorial, we will learn how to build a 4WD robot chassis using aluminum profiles and 3D printed parts. 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. 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. 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. 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 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.
