How do Robots Work

Let’s see the details of the robot first to make you understand how do robots work. 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.

Robots are bots or machines with programmed movements that allow them to move in certain directions or sequences. Artificial intelligence has enabled robots to process information and learn.

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

How do Robots Work?

A robot is made up of the very same components. A typical basic robot has a movable physical structure, a motor, a sensor system, a power supply, and a computer “brain” that controls all these elements.

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 human-made versions of animal life — they are machines that replicate human and animal behavior.

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.

What are the Main Components of a Robot?

What are the Main Components of a Robot

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

On the most basic level, human beings are made up of five major components:

  1. A body structure.
  2. A muscle system moves the body structure.
  3. A sensory system that receives information about the body and the surrounding environment.
  4. A power source to activate the muscles and sensors.
  5. A brain system that processes sensory information and tells the muscles what to do.

How do Delivery Robots Work?

Delivery robots provide an automated door-to-door service, bringing food or other items bought online to the end customer. They are composed of an area for the parcels they deliver, mounted on wheels, and equipped with cameras and sensors. They are autonomous in their functioning.

They provide an alternative to traditional delivery services, leveraging automation and artificial intelligence. Unlike other robots, they aren’t humanoids looking like persons, and they look like moving boxes.

Other delivery robots can fly, such as delivery drones, but we will cover this in future articles on ScrapeWithBots.

Delivery Robots Working

How do Delivery Robots Work

Customers order through a website or an app, picking from select suppliers and providing their location. The delivery robot will then fetch the items from the supplier and deliver them to the customer.

Once the robot collects the item(s), it calculates the best route to your home, considering a wide panel of elements, including road crossings, driveways, sidewalks, and more. Constantly aware of its environment through its sensors and cameras, the robot makes its way slowly but surely to its destination.

When it arrives at its destination, it is unlocked by the same mobile app used to order, with a unique identifier (code, QR code, or else), safely delivering the items without human interaction.

How do Forex Robots Work?

Forex trading robots are automated software programs that generate trading signals. Most of these robots are built with MetaTrader, using the MQL scripting language, which lets 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. Backtesting 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 backtesting 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

Crypto trading bots are bots used to automate trades. They are programs that are executed to yield specific results in trades. Although you can go to a crypto bot trading platform and start using trading bots with pre-defined rules, you can also program them to suit your trading needs.

Crypto trading bots hosted by platforms such as ScrapeWithBots, Coinrule, Cryptohopper, etc.? These platforms create crypto trading bots with specific rules that apply to trades, but you can modify them to suit your specific aim.

  • 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?

This article how do robots work now takes an in-depth look at industrial robots.

An industrial robot is an autonomous system of sensors, controllers, and actuators on an articulated frame that executes specific 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?

The most popular language in robotics is probably C/C++ (C++ is an object-oriented successor to the C language). Python and Java are also very popular due to their use in machine learning and because you can use them to develop ROS packages.


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