Course Structure: 16-Week Self-Study Program

Month 1: Foundations of Robotics

\\Week 1: Introduction to Robotics: What are Robots?\\ \ \\Title:\ The Dawn of Automation: Defining and Classifying Robots\ \\Learning Objectives:\
\ \Define what a robot is and differentiate it from other automated machines.\ \Identify various types of robots and their common applications.\ \Understand the basic components that make up a robot.\ \ \ \\Key Vocabulary:\
\ \\Robot:\ A machine capable of carrying out a complex series of actions automatically, especially one programmable by computer.\ \\Automation:\ The use of largely automatic equipment in a system of manufacturing or other production process.\ \\Manipulator:\ The arm-like mechanism of a robot that moves and positions objects.\ \\End-effector:\ The device at the end of a robotic arm, designed to interact with the environment (e.g., gripper, welding torch).\ \\Actuator:\ A component of a machine that is responsible for moving and controlling a mechanism or system (e.g., motors).\ \ \ \\Lesson Content:\
Robots are more than just fancy machines; they are at the forefront of a technological revolution. But what exactly qualifies as a robot? At its core, a robot is an autonomous or semi-autonomous machine designed to perform tasks. Unlike simple automated machines, robots often possess some level of intelligence, allowing them to perceive their environment, process information, and make decisions. We classify robots in many ways: by their mobility (mobile, stationary), their application (industrial, service, medical), or their control method (teleoperated, autonomous). Regardless of their form, most robots share common components: a mechanical structure (the “body”), actuators for movement, sensors for perception, a control system (the “brain”), and an end-effector for interaction. For example, an industrial robot arm used for welding has a rigid structure, motors as actuators, cameras for sensing, a computer for control, and a welding torch as its end-effector.
\ \\Practical Hands-On Example:\
Research and identify three different types of robots (e.g., an industrial robot, a humanoid robot, a surgical robot). For each, list its primary function, key components you can identify, and one societal impact it has.
\ \

\\Week 2: Robot Anatomy and Degrees of Freedom\\ \ \\Title:\ Unpacking the Robot: Joints, Links, and Movement\ \\Learning Objectives:\
\ \Identify the fundamental mechanical components of a robot: links and joints.\ \Understand the concept of degrees of freedom (DoF) and its importance in robot design.\ \Distinguish between different types of robot joints (revolute, prismatic).\ \ \ \\Key Vocabulary:\
\ \\Link:\ The rigid body segment of a robot manipulator.\ \\Joint:\ The connection between two links, allowing relative motion.\ \\Degrees of Freedom (DoF):\ The number of independent parameters that define the configuration of a mechanical system.\ \\Revolute Joint:\ A rotational joint, like a hinge.\ \\Prismatic Joint:\ A linear joint, allowing translational motion.\ \ \ \\Lesson Content:\
Just as the human body has bones and joints, robots are built from links and joints. Links are the rigid segments, while joints allow relative motion between these segments. The number of independent ways a robot can move or position its end-effector is called its “degrees of freedom” (DoF). A robot arm, for instance, might have 6 DoF – three for positioning (X, Y, Z) and three for orientation (roll, pitch, yaw). Common joint types include revolute (rotational, like a shoulder) and prismatic (linear, like a telescoping arm). The more DoF a robot has, generally the more dexterous and complex its movements can be, but also the more challenging it is to control. Consider a simple robotic gripper: it might only need one DoF to open and close. A complex humanoid hand, however, would require many more.
\ \\Practical Hands-On Example:\
Using everyday objects (e.g., cardboard, paper clips, tape), construct a simple “robot arm” with at least two links and two revolute joints. Experiment with its movement and determine its degrees of freedom.
\ \

\\Week 3: Introduction to Robot Kinematics\\ \ \\Title:\ How Robots Move: Understanding Position and Orientation\ \\Learning Objectives:\
\ \Differentiate between forward kinematics and inverse kinematics.\ \Understand the basics of how a robot’s joint angles relate to its end-effector position (forward kinematics).\ \Appreciate the complexity of inverse kinematics.\ \ \ \\Key Vocabulary:\
\ \\Kinematics:\ The study of motion without considering the forces that cause the motion.\ \\Forward Kinematics:\ Calculating the position and orientation of the end-effector given the joint angles.\ \\Inverse Kinematics:\ Calculating the joint angles required to reach a desired end-effector position and orientation.\ \\Workspace:\ The reachable region of the robot’s end-effector.\ \ \ \\Lesson Content:\
Kinematics is the geometry of motion. In robotics, it’s crucial for understanding how a robot moves. Forward kinematics is like knowing your arm’s joint angles and figuring out where your hand is. You input the angles of each joint, and a mathematical model calculates the resulting position and orientation of the robot’s end-effector. Inverse kinematics is the opposite and often much harder: if you want your robot’s hand to be at a specific point in space, what angles do all its joints need to be? This often involves complex non-linear equations and can have multiple solutions or no solutions at all. For a simple 2-link robot arm, forward kinematics might be a few trigonometric functions, while inverse kinematics could involve solving quadratic equations.
\ \\Practical Hands-On Example:\
Draw a simple 2-link robot arm on paper. Assign arbitrary lengths to the links and joint angles. Using basic trigonometry (sine, cosine), calculate the (x,y) coordinates of the end-effector. This is a manual, simplified forward kinematics exercise.

\\Week 4: Basic Robot Control Systems\\ \ \\Title:\ The Robot’s Brain: Open-Loop vs. Closed-Loop Control\ \\Learning Objectives:\
\ \Explain the difference between open-loop and closed-loop control systems.\ \Identify common components of a closed-loop control system (sensor, controller, actuator).\ \Understand the role of feedback in achieving precise robot motion.\ \ \ \\Key Vocabulary:\
\ \\Control System:\ A device or set of devices that manages, commands, directs, or
