  • Getting Started with TinkerCAD

    TinkerCAD is a free, browser-based 3D design tool by Autodesk. It is ideal for beginners who want to quickly create, modify, and visualize 3D parts. In this section, we will learn how to set up and use TinkerCAD to start designing basic robot components.

    • Step 1: Create a Free Account

      1. Go to tinkercad.com.
      2. Click on Join Now or Sign In.
      3. Create a free account using your email or Google login.

      Step 2: Understanding the Interface

      • Workplane: This is your design surface, similar to a virtual table.
      • Shapes Panel: Pre-made geometric shapes you can drag onto the workplane.
      • Navigation Tools: Orbit, zoom, and pan to move around your model in 3D space.
      • Inspector: Lets you adjust size, color, and settings for each shape.

      Step 3: Your First Design – A Simple Box

      1. Drag a Box shape from the right-side panel to the workplane.
      2. Use the white corner dots to resize it.
      3. Use the black arrows to lift it up or rotate it.
      4. Duplicate the box using Ctrl + D and try combining it with a cylinder or wedge.

      Step 4: Grouping and Aligning Shapes

      • Select multiple shapes using your mouse or Shift key.
      • Click Group (Ctrl + G) to combine them into one part.
      • Use the Align Tool to perfectly center or distribute shapes.

    • Tips for Beginner Designers

      • Keep your designs simple at first – work with basic shapes.
      • Label parts for easy reference.
      • Use colors to indicate different functions (e.g., sensor mounts in red, motor holders in blue).
      • Save your design frequently and use versions to track progress.

      Once you're familiar with the basics, you can start designing robot components like sensor brackets, chassis cutouts, or custom enclosures. In the next section, we'll move on to designing a basic sensor holder step-by-step.
