Getting Started

Welcome to the first installment of the Grand RobotShop Tutorial, a series of 10 lessons that will teach you how to make your own robot. This tutorial is aimed at anybody willing to get started in robotics and have a basic understanding of terms such as “voltage”, “current”, “motor”, and “sensors”. Although this might seem pretty basic, even people with previous robot building experience might find useful information regarding the general method of building a robot.

What is a robot?

There are many definitions of robot and no real consensus has been attained so far. We loosely define a robot as follows:

Robot: An electromechanical device which is capable of reacting in some way to its environment, and take autonomous decisions or actions in order to achieve a specific task.
This means that a toaster, a lamp, or a car would not be considered as robots since they have no way of perceiving their environment. On the other hand, a vacuum cleaner that can navigate around a room, or a solar panel that seeks the sun, can be considered as a robotic system.

It is also important to note that the “robots” featured in Robot Wars for instance or any solely remote controlled device would not fall under this definition and would be closer to a more complex remote controlled car.

Although this definition is quite general, it might need to evolve in the future in order to keep up with the latest advancement in the field. In order to get a sens of how robotics is rapidly growing, we suggest you take a look at the RobotShop History of Robotics.

Let’s get started

This series of tutorials is intended to guide you through the steps of building a complete mobile robot.

There are 10 lessons that will be released in the following 10 weeks. Each lesson guides you through one step of making a general-purpose mobile robot. This will enable you to build your very own mobile robot in order to perform a task of your choice. Each lesson will be illustrated with an example from RobotShop experience in producing the RobotShop Rover. The lessons are intended to be read one after the other and build upon the information gained.

STEP 1

The first step is to determine what your robot should do (i.e. what is its purpose in life). Robots can be used in almost any situation and are primarily intended to help humans in some way. If you are unsure of what you want your robot to do or simply want to concentrate your efforts on specific tasks, here are some ideas:

Knowledge & Learning

LEGO Mindstorms NXTIn order to build increasingly complex robots, most professionals and hobbyists use knowledge they have acquired when building previous robots. Instead of building one robot, you can learn how to use individual components with the objective of building your own "knowledge library" to use to undertake a larger, more complex design in the future.

Amusement & Companionship

Robotics incorporates aspects of many disciplines including engineering (mechanical, electrical, computer), sciences (mathematics and physics) and arts (aesthetics) and users are free to use their imagination. Amusing others with your creations (especially if they are user-friendly and interactive) helps others to become interested in the field.

Competitions & Contests

Robot SoccerCompetitions give the project design guidelines and a due date. They also put your robot against others in the same class and test your design and construction skills. Although many competitions are specifically for students (elementary to university), there also exist open competitions where adults and professionals alike can compete.

Autonomous life form

The next great innovation will be to develop a fully autonomous life form that rivals or surpasses ourselves in ability and perhaps creativity. This goal is still being accomplished in small steps by individuals, research organizations and professionals.

Domestic or Professional tasks

Professional and Service Robots are used in a variety of applications at work, in public, in hazardous environments, in locations such as deep-sea, battlefields and space, just to name a few. In addition to the service areas such as cleaning, surveillance, inspection and maintenance, we utilize these robots where manual task execution is dangerous, impossible or unacceptable. Professional and Service Robots are more capable, rugged and often more expensive than domestic robots and are ideally suited for professional and/or commercial use.

Security and Surveillance

Practical Example

We anticipate that most of you following this guide have the objective of building a robot for learning and knowledge, but also for sheer fun; though many will have a specific idea or project they want to materialize.

The last major consideration is budget. It is difficult to know exactly what people have in mind when they build their first robot; one might already want to build an autonomous snow removal robot, while another simply wants to make an intelligent clock. A simple programmable mobile robot might cost about $100 while a more complex can be several thousands of dollars.

In this exercise, we have chosen to make a mobile platform in order to get an understanding of motors, sensors, microcontrollers and programming, and to include a variety of sensors. We’ll keep the budget to about $200 to $300 since we want it to be fairly complete.

It’s difficult to get too specific without excluding a lot of information which might be relevant to other people. What type of information would you like to know?

Appreciated. What we are trying to do is provide the entire community with information on how to build robots (rather than one robot specifically). If you have any information you would like to know, feel free to add it in the comments section here.

Consider joining a local hobby robotics group.

i want more detailed information & thaxxxxx.

hey .@cbenson …i wnts to be ur frend becoz i need a frend who guide me in every steps in my robot formation

thnx for this site…bt i need more help.is there any site where i can meet few robo frends.

thank you…
This web side is very very…helphful to make the robot at home…
Thank you…once again.

If you have any suggestions as to how we can improve the series, we welcome your feedback.

Well, the “food” would be the battery (or the oxygen in the blood vessels), so the “heart” might be the motor controller(s).

I HAVE MADE A ROBOT THROUGH THIS WEBSITE.THIS WEBSITE IS SO USEFUL TO ME.

Hello to all really i have so interest for this section also i have some CS background but i don’t know how to start and from where i can start ?? any one who has idea plz help me
many thanks

ROBOT IS BEAUTIFUL BY SEEING THIS SITE I MADE A ROBOT IT IS WORKING

THANKU FOR THIS SITE

Thanks for these helpful lessons for how to make a robot. I have been wanting to make a security defense robot for about ehhh 6 months now. I have finally exceeded in making my design on it and these tips will get me outta town! Again thx,

Love, Kitty TurnoverZ

I am also writing to make you be aware of of the really good experience my cousin’s daughter enjoyed checking your webblog. She came to find a wide variety of issues, with the inclusion of what it is like to have an amazing coaching nature to get the mediocre ones effortlessly learn specific extremely tough subject matter. You undoubtedly exceeded my expectations. Thank you for producing these beneficial, healthy, explanatory not to mention easy tips about the topic to Kate.
