Learn How To Build Your First Robot With Step-by-Step Instructions

Apr 30, 2022
link

Once upon a time, robotics scientists were the only people who could design and create robots. Nowadays, “build your own robot” kits are available for anyone who wants to experiment and build a robot from scratch. Be it for children or students, robot-building is now simply a kit away. To help start a journey in robotics, several companies have brought out beginner-friendly kits that are readily available. If you have ever wondered about the best option for a “build your robot kit,” read on to find out the best choice for you.

Why should you build a robot?

Robots are all around us, and we rely on them for many of our daily tasks. We use robot vacuums and cleaners in our households. Robots in factories produce essentially all of the times we use daily. As time goes by and technology progresses, we can expect to see more and more robots everywhere we go.

Constructing a robot will give us an appreciation for the mechanics and technology behind these fascinating machines. Moreover, it will also help improve technical skills and engage the mind. 

Things to know before building a robot

Building a robot is a fun and engaging activity. However, it will help to know some basic concepts before starting a robot-building project. Some of these are:

parallel
  1. Electrical Components: Knowing the names and terms for electrical components will make robot building simpler and faster. Resistors reduce the amount of current in circuits. Capacitors release a charge when there is a drop in electricity. Diodes keep the electrical current flowing in one direction. Transistors act as switch gates that regulate current or voltage flow.
  2. Programming Language: A beginner’s level understanding of embedded programming languages like C++, Python, or Java will be helpful.

What are the parts of a robot?

Before we begin the process of building a robot, let’s go through the parts of a robot:

  1. Chassis – the robot’s frame or “body” is called the chassis. It supports the entire robot and contains its parts. 
  2. Sensors – These devices detect the robot’s environment and send out signals for reaction. Sensors are of different types – infrared, ultrasonic, heat, and pressure.
  3. Processing Unit – The processing unit computes the signals received from the sensors. The processing unit is a logic circuit for most robots. 
  4. Actuators (Motor and moving parts) – The result from the processing unit shows up through the actuators. The three basic types of motors are DC motors, servo motors, and stepper motors.
  5. Battery – It is the source of energy that enables all the other parts of the robot.

How to Build Your Telepresence Robot

A telepresence robot is a computer, tablet, or smartphone-controlled robot that users can manage from remote locations. It is a screen mounted on a wheeled vehicle. Telepresence robots enable users to move around a room and be virtually present. 

Telepresence robots made by companies are often expensive and complicated to use. Building a simple telepresence robot is not hard and can be done with some basic items you can find. 

Telepresence robots have some basic features such as streaming capabilities and mobility.

Follow these steps to find out how to build your telepresence robot:

  1. Tablet: The first step to making a telepresence robot is to get a tablet with a sizeable screen. The tablet will serve as the visual output.
  2. Remote control interface: The next step is to create a remote control interface that will connect the remote to the robot. This step is the most complex step of the process since it requires coding to control motors.
  3. Physical design: The next step is to design the robot’s physical structure.

These are the basic steps involved in building telepresence robots. While it may be good to experiment with making one from scratch, some companies out there offer DIY options. For starters, try this simple yet functional mini-telepresence robot for your phone. 

Smartipresence: A Cardboard Telepresence Robot

Ross Atkins is the mastermind behind the DIY Smartipresence robot. Atkins describes the robot as “a robotic body for your smartphone allowing video callers to move around in your space.” The Smartipresence robot is an extension of the Smartibot kit.

The Smartibot kit comes with the following items:

  • Three sheets of cardboard for different robots (regular Smartibot, Unicorn, and Teabot)
  • Circuit board
  • Battery box
  • Two motors
  • Two small screwdrivers
  • Screws, bolts, nuts, and rubber bands

So how does the Smartipresence work? The first thing you’ll need to do is open the Smartipresence app and send the link to the people you want to call. Your callers will then appear on your phone screen and be able to see what the robot sees and operate it from their smartphone, tablet, or computer.

Making robots has always been entertaining. If you get bored from studies, doing a DIY to create a robot can be stress-relieving. You can even prepare robots from the items present in your house. You don’t have to spend much on the items to build a robot. This article has gone through the various elements required for building your robot for both kids and students, along with instructions for building telepresence robots. Now that you’re ready with the basic knowledge and references for where to get your robot kits, use this opportunity to venture into the field of robotics.
