1. Project Objectives

Master multi-robot cluster control technology by programming four CoCube robots to achieve coordinated formation and circular movement on different sized maps, experiencing precise multi-robot coordination control!

2. Materials Required

3. Software Platforms

1. MicroBlocks——CoCube & CoCube Module

2. Snap

4. Environment Setup

1. Deploy Map: Choose a suitable flat area and lay out the 300x200 or 600x600 positioning map
2. Start Base Station: Follow the basic tutorial method to start the base station and connect your computer to the base station network

• 💡 Tip: You can choose wired or WiFi connection, ensure stable network

5. Configure Four Robots

For easy management, we'll assign IDs to the four robots: 1, 2, 3, 4

1. Connect Robots One by One: Use data cable or Bluetooth to connect each CoCube robot to the MicroBlocks programming environment
2. Set Robot Parameters: Configure each robot with:

• Unique robot ID (Robot 1, Robot 2, Robot 3, Robot 4)
• Same WiFi connection information
• Same router address (default 192.168.10.1)

1. Verify Connection: Ensure all four robots successfully obtain IP addresses and display on the blocks

⚠️ Important Reminder: Each robot's ID must be different, but WiFi information must be identical!

6. 300x200 Map Linear Formation Control

6.1 Import Control Program

1. Download Example Program: Click to download example program 1
2. Import to Snap: Open the Snap website and drag the cocube_snap_example1.xml file into the window
3. View Robot Sprites: You'll see the file has already created four numbered robot sprites!

6.2 Execute Formation Control

1. Understand Control Keys: Click on the stage on the right to see the preset control commands:

• Click green flag: Connect four robots
• Press keyboard "1": Move to starting position
• Press keyboard "2": Start forming a straight line
• Press keyboard "3": Arrange in circle formation
• Press keyboard "4": Circular orbit movement

2. Start Control:

• First click the green flag button in the upper right to connect robots
• After successful connection, Snap's upper right corner will display real-time robot positions, moving the physical robots will show synchronized position changes!

• Then press keyboard number keys "1-4" to execute different formation actions, achieving the effects shown in the video below

3. Custom Programming: Want to modify actions? Click any robot sprite, then drag blocks from the left to create your own formation programs!

7. Step 4: 600x600 Map Exploration Challenge

Through the above example, you've mastered the basic methods of multi-robot cluster control! Now let's challenge a larger map!

Download Large Map Program: Click to download example program 2

This program includes:

• 600x600 map coordinate mapping
• Basic control framework for eight robots
• Expandable programming block combinations

8. Challenge Time 🚀

Now you're a multi-robot control expert! Try these advanced challenges:

• Program four robots to form a square formation for complex geometric movements
• Create a robot "snake" formation, making them move like the game Snake
• Design robot relay races, having them complete different task points in sequence
• What cooler cluster control gameplay can you think of? Start creating!
