Blockly

Blockly is the visual programming mode for Dotbot Flip. It lets you create behavior by arranging blocks in a workspace instead of writing code directly.

When to use it​

Choose Blockly if you want to:

  • start quickly without syntax concerns
  • teach or learn programming concepts visually
  • modify behavior by rearranging logic blocks
  • save and return to different robot programs inside the app

The model and workspace concept​

In the app, Blockly programming is organized around a model or workspace. This workspace acts as the container for the current Blockly program.

That model is used to:

  • build the block layout
  • save the current Blockly program
  • load a previously saved Blockly program
  • switch between different Blockly-based behaviors

This means the workspace is not just the editor view. It is also the vessel used to persist and restore Blockly logic over time.

Typical workflow​

  1. Connect to the robot in the app.
  2. Open Blockly mode.
  3. Create or load a model or workspace.
  4. Add blocks for movement, arm actions, lights, sounds, sensors, or conditions.
  5. Save the workspace when you want to keep the current logic.
  6. Load another workspace when you want to continue a different Blockly program.

Common block groups​

Typical Blockly groups include:

  • logic
  • loops
  • math
  • text
  • arm
  • battery
  • compass and orientation
  • drive
  • lights
  • screen
  • speaker
  • system

Good first Blockly projects​

  • drive forward, stop, and reverse
  • flash the LEDs when a sequence starts
  • move the arm after a short delay
  • create a simple pick-up routine
  • build a basic battle opening move

Why it is useful​

Blockly is a strong middle ground between direct control and text-based programming. It is especially useful in classrooms and workshops, where being able to save and reload different workspaces matters.
