How to Build a Robot

Creating a robot is a great fun. We can describe a robot as ”any automated machine that replaces human tasks, though it may not resemble human beings entirely in appearance or perform functions in a human-like manner.”

An external control device can guide robots or it may be embedded inside. These are interactive, physical, interconnected, and cognitive machines that can perform several tasks. The word ”robot” is derived from the Czech word ”robota” which means ” forced labour”.

The word was first played in R.U.R. play in 1920. The first digitally operated robot was invented in 1954 by George Devol and was called the Unimate. They are used in almost every field including factories, hospitals, military operations, and households.

Before learning how to build a robot understand the types of robot. These are the types of robots that perform different tasks based on their capabilities;

  • Pre-programmed Robots
  • Autonomous Robots
  • Augmenting Robots
  • Humanoid Robots
  • Tele-operated Robots

Step-by-step Guide to Building a Robot:

Here you will learn about how to build a robot. It took the following methods into consideration to build a robot. It requires expert knowledge as it is technical to build it.

We predicate traditional robotics on mechanical and electronic structures for the layout of robots. These robots are normally powered using electromechanical vehicles and are assembled from independent components and materials, each performing a separate function (actuation, sensing, structural).

Conventional robotics is based on rigid substances, which include steel, aluminum, tough plastic, alloys, and composite materials.

Alternatively, tender robotics integrate distinct capabilities into a single material, together with actuation, sensors, adaptivity, and locomotion.

In this context, gentle robots take advantage of clever and multi-useful materials, including elastomers, gels, fabric, and organic materials, which permit the frame of the robot to conform with the encircling surroundings.


As a robot is a machine and to build any machine, you need to have some basic equipment to complete it. An instruction booklet may be required in the manufacturing of robots. We discussed the tools used to build robots below;

2. Actuators and Sensors:

Many types of sensors are used to build a robot that helps them to receive input from outside. For instance, a distance works as an eye and helps them to figure out how far something is. We term actuators as the ”muscles” of the robots. They use this data to move and react effectively.

2. The Processing Unit

The processing unit is the microcontroller of the robots and is often termed ”the Brain of the robot”. It receives data from the sensors and gives commands to the rest of the robot to react accordingly.

For simple DIY robots, two of the most common controllers are Raspberry Pi and Arduino microcontrollers.

3. Batteries

As the processing unit is the brain, the Heart of the robot is the battery. A battery should have enough power to charge all the components of a robot including microcontrollers, actuators, and sensors.

Instead of disposing of a battery, it is better to recharge it. The disposable battery uses up more minerals and also costs more.

4. Robot Chassis

It is the body of the robot. It is a place where you mount all parts and assemble them. You can either make a robot chassis or buy it for your robot. It should have enough space to accommodate the parts and have enough durability to handle its weight.

5. Electrical and mechanical tools

We need various tools in the process of assembling components. You will need at least pliers, a breadboard for prototyping, motors, and screwdrivers. You may need some other tools depending on the components you choose for your robot.

6. Procedure

There are various definitions of the robot which include a cleaning robot, a funny-looking robot, a cognitive robot, and a friendly helper robot. Building instructions are quite helpful in building a robot.

A. Plan your Robot’s purpose and layout:

Robotic designs and functions are simply as essential as mechanical components. Without having a clear purpose for what you need your robot to attain, you can’t recognize where to start. Your quit aim is crucial so one can know which processor, sensors, and actuators will do the task.

B. Choose Your Microcontroller

Once you’ve purpose about the motive and layout of your robot, select your processor and brain. An Arduino or Raspberry Pi suffices to cover simple robot procedures however discover different options.

Select a microcontroller that is more acceptable to your goals and what you want your robot to reap.

C. Accumulate Actuators, Sensors, and Batteries

Reflect on consideration on whether your robot desires a distance sensor, a color sensor, or an infrared sensor. Perhaps it desires all 3 or something entirely different. Make certain you get the proper sensors, automobiles, and electricity supply ready on your robot.

D. Assemble and join the components to the Processor

Do the important wiring to attach the processor, sensors, and actuators. Simple robots, at this degree, typically most effectively use easy DC motors, servo motors, or stepper cars.

Any processor you use ought to have any problem coping with those actuators and connecting them to sensors.

E. Join the Processor on your computer and install the important software

Now that each one of the robot components is connected, it’s time to plug your microcontroller into your computer.

Set up the wanted software for your microcontroller, comprising an Arduino IDE in case you’ve used an Arduino board. There are commonly exact commands for your microcontroller website for this step.

F. Test Your Prototype

The breadboard is available as the programming level starts. Test the various sensors and motors of the robot, using the breadboard and running the code. Figure out if the entirety works nicely and whether you need to add elements like extra sensors.

G. Mount All parts of the robot collectively on the Chassis

If the lot is functioning well, cautiously mount it all up in your chassis. You could buy a terrific robot chassis for an affordable fee, however, you could additionally construct one yourself. If you purchased a robotic-building kit, it has to come with a chassis.

H. Complete the very last trying-out section

Test the robot again to see how the chassis holds up with the sensors and components. Make certain your actuators, along with DC motors, servo motors, or stepper motors preserve up with the chassis.

Look at the sturdiness of the chassis and make sure of the robots’ effectiveness in running applications.

I. Finalize the robot

At this factor, you ought to have what looks like a finished robot. This step is in which you’re making very last adjustments, whether aesthetic or feature-associated. With this accomplished, you have efficiently finished constructing your very personal custom robot.

J. Be Open to further changes

Although your robot is now complete and finalized, be open to creating any modifications for improvement. You could locate if you want more sensors or if the electricity intake is simply too excessive. Be open to adjustments and possibilities to experiment and extend your knowledge.

Unleash your creativity using easily accessible materials and turn your imaginative ideas into a delightful cardboard robot. Perfect for both kids and adults, this project promises an enjoyable and memorable crafting experience.

1. Glue boxes collectively to make the robot body

First, glue the boxes to each other with wood glue. You can use Elmer’s glue, craft glue, or any glue you decide on.

Timber glue is higher because it is very sturdy and thicker than other types of glue, so it doesn’t run all around the vicinity. Also, you can use it for different tasks as it’s so versatile.

2. Disguise seams with gummed paper tape

Cover any seams that you didn’t want to reveal with paper tape. Gummed paper tape is something to have around because it dries pretty quickly, completely blends into cardboard, and may be painted. It is historically used to stretch watercolor paper.

It works like old fashion stamps. You tear or cut a bit of paper tape off the roll and in short dip the whole length in a bowl of water, then stick it to the part you need to adhere and cover. You may slide it into position a bit, however, then you need to leave it alone to dry.

It’s sturdy as soon as it dries. You can use duct tape if you would like, however, you will sincerely see the rims of the tape, even though the paint is.

3. Make ear bolts and fingers

Cut a Styrofoam ball in half for the “ears” on both sides because they look like the end of bolts. Then bent a clothes hanger right into a coil and glued it on top of the head to look like wiring. The expandable dryer vent hose worked properly for the hands.

Reduce a hole slightly smaller than the diameter of the hose (4-inch hose) and feed the primary couple rings of hose into the hollow. Making the hole slightly smaller than the hose diameter saved it in area well.

4. Time to color your cardboard robot

Let your creativity come out. You can use cheap house paint, tempera paint, or acrylics something you feel like the use of. House paint is better because it covers nicely and is fairly cheap.
