\Welcome to the exciting world where mathematics meets robotics\! In this first lesson, we’ll lay the groundwork by revisiting fundamental number systems and the basics of algebra. Think of it as learning the alphabet before you can write a story. Robots, at their core, process and act upon numerical data. Understanding different number types helps us appreciate the precision needed in robotics. For instance, a robot’s position might be an integer (e.g., grid square 5,5), but its exact joint angle would be a real number (e.g., 30.75 degrees). Scientific notation is vital for handling very large or very small numbers, common in sensor readings or complex calculations. We’ll then move to algebraic expressions. Variables are placeholders for unknown quantities, like the robot’s speed (v) or the time it has traveled (t). Constants might be fixed values like the robot’s wheel radius (r). Simplifying expressions helps us to make calculations more efficient and understandable. For example, if a robot travels at speed ‘v’ for time ‘t’, and then stops for ‘t/2’ before traveling another ‘v\*t’, understanding how to combine these terms simplifies predicting its total movement.\
\
\\Hands-on Example:\
\Imagine a simple mobile robot moving in a straight line.\
\
\Let ‘d’ be the distance it travels.\
\Let ‘s’ be its constant speed.\
\Let ‘t’ be the time it travels.\
\The basic relationship is \d = s \* t\.\
\
\Now, let’s say the robot travels for 5 seconds at a speed of ‘s’ meters/second, then increases its speed by 2 m/s for another 3 seconds.\
\
\Write an algebraic expression for the total distance traveled.\
\If \s = 1.5 m/s\, calculate the total distance.\
\\Solution Guidance:\ The first segment is \5 \* s\. The second segment is \3 \* (s + 2)\. The total distance is \5s + 3(s + 2)\. Simplify and substitute.\
\
\
\
\Lesson 2: Solving Linear Equations and Inequalities\
\
\\Learning Objectives:\
\
\Solve linear equations for a single unknown variable.\
\Understand and solve basic linear inequalities.\
\Apply equation-solving techniques to simple robotics scenarios.\
\
\
\\Key Vocabulary:\
\
\\Equation:\ A mathematical statement that shows two expressions are equal.\
\\Inequality:\ A mathematical statement that compares two expressions using symbols like \<, \>, ≤, or ≥.\
\\Solution:\ The value(s) of the variable(s) that make an equation or inequality true.\
\
\
\\Content:\
\Equations are the language of control in robotics. If you want a robot to reach a specific target, you’re essentially solving an equation for its path or joint angles. Linear equations, which involve variables raised only to the power of one, are incredibly common. We’ll cover methods for isolating the unknown variable, such as inverse operations (addition/subtraction, multiplication/division). Inequalities are also crucial; for example, a robot might need to maintain a distance \greater than\ a certain threshold from an obstacle, or its motor speed must be \less than or equal to\ a maximum value. We’ll explore how to solve these and represent their solutions.\
\
\\Hands-on Example:\
\A robotic arm needs to move an object. Its current position is \P\_current = 2x + 5\ units from the base, and its target position is \P\_target = 17\ units.\
\
\Write an equation to find the value of ‘x’ that gets the arm to the target.\
\Solve for ‘x’.\
\Now, imagine the arm needs to be at a position \P\_current\ that is \at least\ 10 units from the base. Write and solve an inequality for ‘x’.\
\\Solution Guidance:\ For the equation, \2x + 5 = 17\. For the inequality, \2x + 5 ≥ 10\.\

Week 3-4: Fundamentals of Geometry
\Lesson 3: Points, Lines, and Angles in 2D Space\
\
\\Learning Objectives:\
\
\Understand coordinate systems (Cartesian) for representing points in 2D space.\
\Calculate distances between two points.\
\Identify and measure different types of angles (acute, obtuse, right, straight).\
\
\
\\Key Vocabulary:\
\
\\Cartesian Coordinate System:\ A system that specifies each point uniquely in a plane by a pair of numerical coordinates, which are the signed distances to the point from two fixed perpendicular directed lines, measured in the same unit of length.\
\\Origin:\ The point (0,0) in a coordinate system.\
\\Distance Formula:\ A formula used to calculate the distance between two points in a coordinate plane.\
\\Angle:\ The space (usually measured in degrees or radians) between two intersecting lines or surfaces at or close to the point where they meet.\
\
\
\\Content:\
\Robots live and move in space, so understanding geometry is paramount. We start with the basics of 2D space, which is often sufficient for mobile robots moving on a flat floor or for planning movements on a 2D map. The Cartesian coordinate system (x, y) is our primary tool for pinpointing a robot’s location or the position of an object. Calculating distances is essential for navigation, collision avoidance, and reaching targets. Angles dictate how a robot’s joints move or how it turns. We’ll cover how to represent these fundamental elements
