Robot anatomy

In this lesson, we'll explore the anatomy of robots and learn about the components that make them work, including sensors, actuators, and controllers. We'll also learn about robot bodies, locomotion, end effectors, and power supplies. By the end of the lesson, we'll have a better understanding of how these elements influence the design and function of robots.

Learning Goals Learning Outcomes

1 - Introduction

Welcome to our exploration of robot anatomy! This is a fascinating area in robotics that deals with the physical structure and parts of a robot. It's like learning about the bones and muscles in our bodies, but for robots!

Understanding robot anatomy is key if you want to design or build robots that can carry out specific tasks. This knowledge will help you understand how robots function and how they can be used to make our lives easier and more fun. So, let's dive in and start learning!

2 - Exploring Robot Components

Robots are like puzzles, made up of many different pieces that all work together. These pieces can include things like sensors, which are like the robot's eyes and ears, giving it information about the world around it. There are also actuators, which are like the robot's muscles, helping it to move.

And then there's the controller, which is like the robot's brain, running the software that tells the robot what to do and when to do it.

By learning about these different parts of a robot, you'll start to understand how they all fit together to make the robot work, and how they can be designed and programmed to help the robot do specific tasks.

3 - Robot Body

Let's delve deeper into the body of a robot, also known as its structure or chassis. The body of a robot can take on many different shapes and sizes, depending on what it's designed to do. It could look like a human, an animal, or something completely unique.

The robot's body is important because it houses all of its components and provides the framework that allows the robot to perform its tasks. For example, a robot designed to pick up objects might have a body that includes a claw or arm, while a robot designed to explore rough terrain might have a body that includes wheels or tracks.

4 - Robot Locomotion

Locomotion is a crucial aspect of robotics. It determines how a robot moves and interacts with its environment. In this step, we will explore different types of robot locomotion and understand how they work.

1. Wheeled Locomotion: This is the most common type of locomotion. It is used in robots that move on flat surfaces. Examples include robotic vacuum cleaners and automated guided vehicles in factories. To understand this, imagine how a car or a bicycle moves. They use wheels to roll on the ground, right? Similarly, robots can have two, three, or more wheels depending on their design.

2. Legged Locomotion: Some robots use legs for locomotion, similar to humans or animals. These robots are designed to traverse uneven terrains where wheeled robots might struggle. Think of a robot dog or a humanoid robot. They use legs to walk, run, or even jump.

3. Tracked Locomotion: This type of locomotion is used in robots that need to move over rough terrain, climb stairs, or move over obstacles. Think of a tank or a bulldozer. They use tracks instead of wheels to move around.

4. Flying Locomotion: Some robots are designed to fly. These are usually referred to as drones. They use propellers to lift off the ground and fly in the air.

5. Swimming Locomotion: Robots designed to move in water use this type of locomotion. These are often used for underwater exploration and research. They use fins or propellers to move through water.

Now that you have learned about different types of robot locomotion, think about a robot you would like to design. What type of locomotion would it use and why? Write down your thoughts and ideas.

5 - End Effectors

End effectors, often referred to as the 'hands' of a robot, are the tools or devices that are attached to the end of a robot's arm or body. They are crucial components that allow the robot to interact with its environment in a meaningful way.

There are many types of end effectors, each designed for a specific task. For example, a gripper end effector is used to pick up and hold objects, while a welding torch end effector is used in manufacturing processes. Other end effectors can include cameras, sensors, or even paintbrushes for robots designed to create art.

Now, let's explore some common types of end effectors:

  • Grippers: These are used to grab and hold objects. They can be simple, like a two-fingered claw, or complex, like a human-like hand.
  • Welding Torches: These are used in manufacturing to fuse materials together.
  • Drills: These are used to make holes in objects. They are commonly found in manufacturing and construction robots.
  • Sensors: These are used to gather information about the robot's environment. They can detect things like temperature, light, or distance.

Understanding the different types of end effectors and their functions is key to designing and building effective robots. By choosing the right end effector, we can ensure our robot is well-equipped to perform its intended task.
