 Introduction to Robotics with Spike Prime What is Spike Prime? Spike Prime is a robotics learning kit developed by Lego Education, designed for students to build, program, and learn through hands-on experimentation. It combines LEGO building elements with programmable motors and sensors, allowing students to create various robotic models and machines. The Spike Prime kit uses block-based coding (inspired by Scratch), making it accessible to beginners, especially children, while still offering depth for more advanced projects. Key Components of the Spike Prime Kit: Spike Prime Hub: The brain of the robot, also known as the Programmable Hub, is a compact, intelligent brick that controls the motors and sensors. It includes: A 5x5 light matrix. Multiple ports for connecting motors and sensors. Bluetooth capabilities to connect wirelessly to a computer or tablet. Built-in gyroscope and accelerometer. Motors: Large Motor: Provides strong power, ideal for moving heavy parts of the robot. Medium Motor: Offers precision and speed control, perfect for more delicate movements, such as in robotic arms. Sensors: Color Sensor: Detects colors and light intensity. Often used for line-following robots or detecting specific colors. Ultrasonic Sensor: Measures the distance between the robot and objects in its path. Commonly used for obstacle detection. Force Sensor: Measures physical pressure, useful for projects like gripping or detecting contact. Gyro Sensor (in-built): Detects the robot’s orientation and helps with turning and maintaining direction. LEGO Technic Elements: These are structural components that help in building the robotic models, offering flexibility in design and engineering structures.  Autonomous Vehicle Learning Notes Ultrasonic Sensor/Distance Sensor: The ultrasonic sensor is used to detect objects by measuring the distance between the robot and an obstacle. It works by emitting sound waves and measuring the time it takes for the echo to return. Common use: Stopping the vehicle when an obstacle is within a set distance (e.g., 10 cm). Color Sensor: The color sensor detects different colors on the surface, which can be used to follow a line (e.g., black) or respond to specific signals (e.g., red for stop). Common use: Line-following in maze-solving robots or traffic signal recognition in autonomous vehicles. Programming Concepts: Loops (Forever Block): Repeatedly check sensor values (e.g., ultrasonic or color sensor) to control the robot's behavior in real-time. If/Else Conditions: Use conditional blocks to decide what the robot should do based on sensor input (e.g., "If the distance is less than 10 cm, stop"). Motor Control: Control the robot's movement through motors. For example, turning left or right by setting different motor speeds.  Robotic Hand (Prosthetic Arm) Learning Notes Force Sensor: The force sensor measures the amount of pressure applied to it. It is useful in projects where the robot needs to grip or detect physical contact. Common use: Detecting when the robotic hand should close or release based on the amount of force applied. Ultrasonic Sensor (in Robotic Hand): This sensor can also be used in the robotic hand to detect the distance between the hand and an object. The hand can grip when an object is detected within a certain range (e.g., 5 cm). Motor Control: Motors in the robotic hand control the opening and closing of the fingers. You can program specific movements (e.g., closing when pressure is detected) using motor blocks. Programming Concepts: Loop (Forever Block): The hand will continuously check the force or ultrasonic sensor and respond by gripping or releasing objects. If/Else Conditions: Use conditions like “If the force is detected, close the hand; else, open the hand.”  Programming Basics in Spike Prime: Loops (Forever, Repeat): These blocks allow the robot to repeatedly check conditions or perform actions, such as continuously moving forward or checking for obstacles. Conditional Statements (If/Else): These blocks enable decision-making in the robot’s program. For example, the robot can be programmed to stop when it detects an obstacle using the ultrasonic sensor, or follow a line based on the color sensor. Motor Control: Students learn to control the speed and direction of the motors, allowing the robot to move forward, backward, or turn precisely. Sensor Integration: By using data from sensors like the color sensor or ultrasonic sensor, students can program the robot to interact with its surroundings. For instance, the robot can detect an object in front of it and stop to avoid a collision.
