From an early age, many have fantasized about making robots, but the actual process of doing so could seem too challenging. As a result, we put that creative urge to rest by relegating it to fantasy. For this reason, building simple robots on a Raspberry Pi is one of its most well-liked uses. People still find creating robots fascinating, even if it is a hobby or a stepping stone in their education. With the guide we provide, you may start learning how to construct a robot with a Raspberry Pi immediately if you’re interested in stepping into the field of robotics.
Link the Pi to the Motors
A soldering iron, solder, wire leads, a holder for four AA batteries, two 3V to 6V DC motors, a motor controller, and a Raspberry Pi should all be gathered. Remove the outer jacket from the ends of your wires to begin, then solder two different cables to the terminals on one motor. Repeat the process using the second motor. The other wire ends should then be connected to the motor controller connections. They have the designations OUT1 through 4. Put the wire ends through each terminal’s screws after loosening them, and then tighten them again.
Using a red wire in VCC and a black one in GND, attach the wires to the motor controller terminals using the same procedure. The battery holder should receive the other ends of these. Depending on the motor controller you are using, finish by attaching your motor controller board to your Raspberry Pi. You might anticipate using cables to link the Raspberry Pi’s ln1–4 and GND (not to be confused with GND terminal) pins.
Set the robot’s course.
Enter the following into mu in the Raspberry Pi programming menu:
Robot from gpiozero import
Robot(left=(7,8), right=(9,10), [robot name]
The [robot name] doesn’t need to be included in brackets and can be anything you choose, like rob. We use the frames to indicate that the robot name should be entered in that area. Save your work, launch a Python Shell by clicking the terminal button, typing “python,” and then press the enter key. To stop the motors, use the robot. Stop after typing [robot name].forward to check which directions they are turning in (). One motor will turn on when [robot name].right is entered. Your suitable motor will be this, and your left motor will be the one that did not move. If the wired ends are pointing to the right from your perspective, ensure that when you instruct [robot name].forward, the spinning components of the motor rotate clockwise.
Complete the robot
Create the robot’s body to finish. Although there isn’t a set procedure to follow, you should make sure that all the parts can fit inside the body you create. Using a board or box where you can attach the components should be fine. Typically, the controller and Raspberry Pi are placed at one end, in front of the left and suitable motors, and at the back end of the body (corresponding to the left and right of the robot). The motors’ left and right spinning components should protrude from either side to attach axles and wheels to the engines. To help the front end roll, you can utilize one ball caster or several wheels.
You should now have a straightforward working robot. Purchase a Raspberry Pi kit and other electronics products, such as micro bit kits, from the Chicago Electronic Distributors website to put your knowledge of how to create a robot using the Raspberry Pi to work.
