How do Robots Work

To understand how do robots work you must have thorough knowledge about ‘Robot’. The word robot comes from the Czech word “robota,” which means “forced work or labor.”

Today, we use the word “robot” to mean any man-made software bot and industrial bot. This machine can perform work or other tasks automatically or by remote human control. Artificial intelligence has enabled robots to process information and learn.

Here we cover how do robots work with different robots like forex robots, crypto trading bots, and industrial robots.

How do Robots Work?

Robots are all around us! Robots work with the help of AI, Programming languages, and a physical structure in different ways according to their categories. A robot is made up of these components. In a typical robot you will find a motor, a sensor system, a moveable physical structure, a power supply, and a computer “brain” to control all the functions properly.

Approach: Robots use sensors, actuators, and algorithms to take in information from their environment, process it, and use it to perform tasks autonomously.

Essentially, robots are designed to imitate the animal and human behavior _ in other words they are human-made versions of animal life.

You can think of the robot as a machine with a computer application operating it—the robot’s components form two large groups: hardware and software.

·       Hardware

A robot’s hardware includes the body, motors, and sensors.

The body shape depends on the type of robot or the application field. Some examples of a robot’s body include humanoid robots, arms-only, legs-only robots, and wheeled robots.

·       Software

Software controls the robot. Without software, the robot won’t be able to operate. In many cases, the robot’s software has parameters you can set, for example, with a smartphone application or a dedicated input device, like buttons.

Any robot is made up of three parts – Sensors (for input), CPU (processor), and Mechanical Actions (for output).

How do Delivery Robots Work?

The emergence of ‘Delivery robots’ provide customers with the automated door-to-door service. They are used to deliver food or other items bought online to the end customer. These robots have a separate area for the delivery of parcels, mounted on the wheels and is equipped with sensors and cameras. They function autonomously.

The manipulation of automation and artificial intelligence in the form of delivery robots introduced a new alternative to typical delivery services. Their appearance is not like other humanoids looking like persons, rather you’ll find them in the form of moving boxes.

There are some drones that can fly like delivery drones, if you want to learn about them then read our future articles on ScrapeWithBots.

Delivery Robots Working

How do Delivery Robots Work

The delivery robots usually work through a website or an app. Because nowadays customers prefer to shop from a website by picking up the items from select suppliers and providing their location. These delivery robots will fetch the products from the retailer and deliver them to the customer. 

After collecting the items from the supplier the next task for the delivery robot is to find out the best and convenient rout to the customer’s home. For this robot consider a long list of elements like driveways, road crossings, driveways, sidewalks and more. The cameras and sensors on the robot make its journey easy by keeping it update about it’s environment and the robot makes its way slowly but surely to its destination.

Finally, when a delivery robot reaches it’s destination, the same mobile app or website is used to unlock the robot, with a unique identifier(code, QR code, or else). So, the items are delivered safely without any human interference.

How do Forex Robots Work?

Forex robots _ automated trading systems are introduced to generate trading signals.  In this field most the forex robots you will encounter are built with MetaTrader that use MQL scripting language. It lets the traders generate trading signals, place orders and manage trades.  How do Forex Robots Work

·       Software Programming

One of the main characteristics of Forex trading robots is that they rely on mathematical algorithms to find a trade setup. To do so, many Forex robots incorporate various technical indicators, which are then used to decide whether to buy or sell a currency pair.

·       Trading Strategy

A forex trading strategy is a set of rules a trader uses to buy and sell currency pairs. You would normally create a trading strategy and follow it manually, but many use computer programmers to implement an automated trading strategy.

·       Testing phase

After the first version of your trading robot has been programmed, it needs to be tested to demonstrate proof of concept. The testing phase is divided into two phases: software testing and market testing.

·       Trade Decisions

A forex robot or an expert advisor refers to a piece of software coded with instructions for automatically making trade decisions without the direct intervention of the trader.

·       Technical Parameters

Usually, a trader can adjust the technical parameters to suit the prevailing market conditions, which could maximize the robot’s profitability. So, a trading robot generates signals whenever the stipulated market factors and other trading conditions are met.

·       Back Testing

In this form of testing, forex trading robots are tested to trade within the market based on historical data. Back-testing enables traders to see whether the forex trading robot follows the precise rules it was coded to execute and the strategy’s viability.

·       Forward Testing

Although results generated from back-testing can be a good indication of a trading robot’s success, the differentiating factor of a forex trading robot from others is whether it can accomplish profitability in real and current markets.

How do Crypto Trading Bots Work?

How do Crypto Trading Bots Work

In order to know ‘How do Crypto trading bots work?’, first learn the purpose behind their creation. In this era of technology when everything is automated, Crypto trading bots are introduced to automate trades. If you want to yield certain results in trades, Crypto trading bots are programs to go with. The best thing is that you can visit a bot trading platform and start using it with pre-defined rules but you can also use it according to your trading needs by programing it on your own. 

The platforms like ScrapeWithBots, Coinrule, Cryptohopper, etc. host Crypto trading bots. Although the crypto trading bots designed by these platforms function according to the specific rules of trades, but you can use and modify the bot according to your specific aims too.

  • Crypto bots analyze data, predict risk and buy and sell assets as per their calculations. They watch the market and trade when certain market conditions are met. Most crypto trading bots work by connecting directly to a cryptocurrency exchange.
  • After the bot successfully connects to the exchange, it starts watching the market and waiting for certain events or changes in prices. Once it detects an event, it will signal you to take action or decide based on the rules you’ve defined and take the required action (buy/sell) itself.

How do Industrial Robots Work?

As we are discussing about how do robots work now we’ll take an in-depth look at the workings of industrial robots?.

An industrial robot is a combination of sensors, actuators and controllers on a segmented frame in an autonomous system which is used to execute certain functions and operations in a manufacturing or processing line.

How do Industrial Robots Work


The main structure of an industrial robot is the arm. The arm is a structure made of links and joints. Links are rigid components that move through space in the range of the robot.

The joints, on the other hand, are mechanical parts that connect two links while allowing translational (prismatic) or rotational (revolute) movement.

Major Components

A robotic system has three major components:

  • A mechanical part: the arm itself, which is composed of motors on each axis.
  • An electronic part: the control cabinet with its central unit, which ensures the servo control, its sensors, and speed variations.
  • A computer part is a specific programming language that allows the robotic machine to be controlled by linking it to its user and environment. This computer part includes a calculator that converts the coded motor data into Cartesian values.

Working of Industrial Bots

There are multiple designs of pick-and-place robots based on the specific application for which they are used. The basic principle of most of these designs is on similar lines.

Important: Industrial robots use programmed instructions to automate tasks such as welding, painting, assembly, and product inspection.

These robots are typically mounted on a stable stand and have long arms that can reach their entire area of operation. The end of the arm attachment is specialized to the type of objects the robot intends to move.

Working with these bots and how robots work usually involves the following parts.

·        Robot Arm tool

A robotic arm, also known as a manipulator, is the extension of the robot by using cylindrical or spherical parts. Links and joints.

·        Sensors

You can think of sensors as the eyes of the robots. The sensors do the tasks like identifying the position of the object.

·        Controllers

Controllers synchronize and control the movement of different robot actuators, thereby being the brain behind the smooth robotic operation.

FAQS: How do Robots Work?


This post tries to give a broad, hopefully easy-to-understand basics of how do robots work and the fundamentals of the robots and control system.
