Program for Pallo - SPIKE Prime catapult with target robot - LSAv3.4.5.llsp3

This program is for the target part of Pallo. It uses a piston with differently colored sections, which are detected by a color sensor.

The piston starts with a green section, so the program waits for that color to change—indicating that the target has been hit. Then, it celebrates!

The celebration is simple: the program reads the color of the new section to determine how accurately the target was hit, and it lights up the center button with that color. It also displays "YAY" on the hub's screen.

Feel free to improve the program however you like!

Build, Code, Play: Your First Adventures with SPIKE Prime

Welcome to an introduction to the SPIKE Prime set! In this course, you’ll find 7 step-by-step 3D building instructions for SPIKE Prime robots, designed to help you explore the full potential of the base set. Once you've built them, you can bring them to life with our fun programs—these range from simple tasks like moving forward to more complex actions like detecting the nearest object.

And if you're ready for a challenge, we’ve also prepared some advanced tasks! These will encourage you to research and experiment with both the programs and the robot itself. Of course, you're always welcome to add your own creative touches and enjoy the process along the way.

Lesson 6 - Catapult

Introduction

content picture

In this lesson, you are going to build Pallo - the SPIKE Prime catapult with a target robot! The robot consists of two parts: the catapult and the target. The catapult uses rubber bands to launch a projectile and features an axle mechanism to keep it loaded. It contains no electronic components—because it’s just too much fun to fire it yourself!

The second part is the target. It includes a piston with differently colored sections. When the piston is hit, it moves, and a color sensor detects the impact! The colors are arranged like a real target: yellow at the center for a perfect hit, followed by red for a near miss, and blue for the outermost area. The target's program makes it celebrate when a hit is detected!

But first, let's build the robot!
