Webots Tutorial #2: Create Your First Physics Objects, Ball & Walls from Scratch!

In this 30-minute beginner-friendly tutorial, we follow the official Webots Tutorial 2 and learn how to build a complete physics-enabled environment from the ground up! What you’ll learn: 1. Create a brand new world starting from your Tutorial 1 simulation Replace the default arena with a custom 1 m × 1 m floor 2. Understand the all-important Solid node and rigid body concepts 3. Add a bouncing physics ball using Sphere geometry 4. Set up proper graphical appearance with PBRAppearance (realistic rough plastic look) 5. Use the same geometry for both rendering and collision with the powerful DEF-USE mechanism 6. Optimize your scene by reusing Shape nodes instead of duplicating geometry 7. Build four static walls around the arena using only ONE Shape definition 8. Make objects dynamic (affected by gravity) or static 9. Tips for simulation efficiency and performance By the end of this video, you’ll be able to: - Confidently create and organize Solid objects - Apply physics correctly - Keep your world file clean and efficient using DEF-USE - Build simple enclosed environments for robot testing Perfect for robotics students, researchers, or anyone starting with Webots in 2025!
