The robot needs something to tell the motors when to turn, how fast, and for how long. The robot also needs a way of deciding if it needs to turn left or right, stop, and how to interpret signals from its sensors. In short, the robot needs a brain. 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. 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.

The connection between the RC receiver and the Sabertooth is simple. The motor driver has four screw terminals: GND, 5V, S1, and S2. 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 brain of the robot is the Arduino Uno. Based on inputs from sensors, the Arduino acts on logic that is written by the programmer, and creates outputs. 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. The rugged treads and programmable grippers make Roli an ideal robot for collaborative problem-solving. Teach students about exploration and discovery with robots.void setup() { Serial.begin (9600); pinMode(trigPin, OUTPUT); pinMode(echoPin, INPUT); // pinMode(led, OUTPUT);// // pinMode(led2, OUTPUT);// Add sensors, an Arduino board and a Raspberry Pi board to detect obstacles and communicate wireless with the robot; Resources: Using computer jumper wires negates using special cables, or regular wire could be soldered to the pins. When soldering, it is good practice to use different colored wire to avoid confusion, or when jumpering use different colored jumpers if they are available. This is our second generation of the LT-F robot. It is the same chassis that we offer with our tacti..

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.This distance/range sensor connects to the EZ-B v4 with a single wire and includes a built-in power supply. The sensor uses ultrasonic sound to determine the distance of an objects. 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.

An Arduino Shield is a component that can be placed over the Arduino and all the pins of the shield line up with the receptacles in the Arduino. This arrangement makes it very easy to have multiple components without worrying about the logistics of the wiring. This is where the robot pictured will differ from the robot that will be produced from this Instructable. The pictured robot uses a different version of the Seeedstudio Motor Shield, a version 1.2 instead of version 2.0. The 2.0 version is an improvement as it doesn't use the proprietary Grove style connectors, and it is now possible to use jumpers instead, which are cheaper. The EZ-B v4 is the next generation brain of your robot or IoT device, powering over 20,000 robots worldwide! Give your custom robot or IoT project features inspired from science fiction! With the electronics protected by a stylish plastic shell, the EZ-B v4 clips into your EZ-Robot Revolution chassis or custom robot. It is easily controlled over Wi-Fi using EZ-Builder software. A great way to power the robot is by using a high technology Lithium polymer battery. These batteries will power your robot for hours. Judge the capacity by the mah (milli-ampere-hour) rating, a higher number means higher capacity.
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 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. 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 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).

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. 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. 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 HC-SR04 Ultrasonic Distance Sensor is the eye of the robot. With the HC-SR04 it is possible for the robot to gather real world information to feed to the Arduino brain. To be more accurate, the HC-SR04 uses sonar more like a bat, sending out sound waves and measuring the time it takes for them to return. By using the speed of sound, it is possible to calculate the distance between the sensor and the object being detected. 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 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.
