Iteration 007


This page provides details about iteration 007 of CyberPi.

Most iterations upgrade the product incrementally while being compatible with earlier versions, so the programs you compile for earlier versions can be used in the latest version.

Understanding the information on this page may require some background knowledge. If you have already purchased the latest version of CyberPi, or are using an earlier version and have no questions about feature updates, you don’t have to read this page.

New features

Wi-Fi-based field control

In 433 band-based field control mode, MakeboX communicates with the power management module on the robot through the 433 band and thus controls the robot and obtains its status information.

In the Wi-Fi-based field control mode, MakeboX interacts with the robot based on the Wi-Fi ESP32_NOW protocol. In all the coming competition events where CyberPi is used, MakeboX will control robots and obtain their status information in the Wi-Fi-based field control mode.

CyberOS UIs

The following UI is added on CyberOS. Choose Settings > About CyberPi to find it. After you scan the QR code with your smart phone where the MakeX officiating app is installed, your smart phone, MakeboX, and CyberPi can communicate with each other wirelessly.

With the Wi-Fi-based field control technology and MakeboX, the MakeX officiating app can pause, restart, and monitor the status of robots in competitions, which can be expected in the some of 2022 competitions.

New block and MicroPython API

Block (available only in Upload mode) API

You can find this block in the Sensing category after adding CyberPi from the device library.



Determines what stage CyberPi is in. Parameters:

  • name str, indicating the possible state of a competition. Value range:
    • auto:automatic mode
    • manual:manual mode

Returns a boolean value.
Note: A competition can be in another state instead of these two states, subject to the default states you have defined on CyberPi before connecting it to MakeboX.

Official release of the Bluetooth Controller extension for CyberPi

The 007 firmware officially supports the Bluetooth Controller extension, and you can use the following blocks to write your programs.

Chassis calibration

The chassis calibration function is added. With this function, after you change the wheelbase and wheel diameter of mBot2, it still can execute commands, such as turning 90 degrees, accurately through calibration and intelligent turning coefficient setting. In addition, this function, to some extent, resolves the problem of inaccurate turning caused due to improper building of mBot2.

Block (available only in Upload mode) APIs


Showing expression with the 8×16 LED matrix

An expression block is added in the 8×16 LED Maxtrix extension for CyberPi. You can use this block to write programs for mBot2, making it a robot with emotions.

Block (available only in Upload mode) APIs























Official release of the Network extension

In version 007, bugs reported by users are fixed and the Network extension is officially released. You can use it to teach network communications.

Your feedback and suggestions are welcome, and we will improve the extension accordingly to give full play to the value of CyberPi in education.

Blocks (available in both Upload and Live modes) Function API(s), password), password)

Determines whether CyberPi connects to the network


Example: ‘’
ip : ‘’

port: 5050, port)[index]
Sends a message with a line break

data: str

ip_to: str

port: int, ip_to, port)
When this API is run, CyberPi listens for messages from at the port it specifies. When a line break is received, CyberPi determines that a full line of data is received and returns the received message.

ip_from: str

port: int, port)


port:int, ip_to, port)
When this API is run, CyberPi listens for messages from at the port it specifies until the data received reaches the specified length, and CyberPi will return a message at the specified length.

ip_from: str

data_size: int

port: int, data_size, port)

In Simple Network mode, CyberPi works as a client (STA) by default and connects to other non-CyberPi devices (e.g. a phone, a server on a LAN). By default, port 5050 is used to implement data communication.

Blocks (available in both Upload and Live modes) Function API(s)
Establish a connection between CyberPi and the AP with the corresponding ssid, password, and ip address. Set CyberPi as a client., password), port=5050)

Change your IP address
Connect to a “server” at a specific address and send a message, port=5050), ip_to, port)

Read data from a specific server, port=5050)

Providing the user cloud message function in Python 3 programming [coming soon]

We will soon update the Python 3 library for Cyberpi to support the user cloud message function. Stay tuned to the updates in the Python API Documentation for CyberPi.

BUG fixes and user experience improvement

Added Python 3 Programming for mBot2 [coming soon]

Most of the features supported by MicroPython will be supported by Python 3. For example, mBot2 will support Python 3 programming.

Stay tuned to the updates in the Python API Documentation for CyberPi.

Modified the Wi-Fi function

In versions earlier than 007, CyberPi automatically connects to the Wi-Fi network it has connected to last time, which affects the ESP32-NOW communication. Therefore, this function is deleted, and you need to connect CyberPi to the Wi-Fi network through the block or API.

Blocks (available in both Upload and Live modes) Function API
CyberPi stores the name and password of the last Wi-Fi network it has connected to and connects to that network when this block is used. cyberpi.wifi.reconnect()
Disconnects CyberPi from the Wi-Fi network

CyberPi is restored to the default communication channel to ensure the LAN broadcast quality of the CyberPi.


Modified the fast charging function for mBot2

To improve the fast charging experience on mBot2, the fast charging activation function is deleted. You don’t need to activate fast charging any more. In version 007, by default, fast charging is enabled when the power switch of mBot2 is turned off.

Optimized CyberOS

Updated the start UI

The start UI is updated due to the new VI of Makeblock.

Modified the menu hierarchy and items

  • Programs are categorized into Preset and My programs after you choose Switch Program.
  • The items About CyberPi and Reset CyberPi are added after you choose Settings.
  • The option Activate fast charging is deleted.

Revised texts

Known text mistakes are corrected.

Increased the function of the HOME button

After pressing HOME to enter CyberOS, you can press HOME again to quickly return to the homepage.

Added the function for displaying the battery level of an external battery

After connecting the enhanced mBot2 Shield to CyberPi, the external battery level is also displayed. You can clearly see the status of both the internal and external batteries.

(The battery icon on the right indicates the power level of the internal battery, and that on the left indicates the power level of the external battery.)

Block and MicroPython APIs

Blocks (available in both Upload and Live modes) APIs

Returns the power level of the external battery, 0–100

This function is available only for mBot2 Shield V1.2.

Added the function for displaying the firmware version of an extension board

Choose Settings > Update. The firmware version of the extension board is shown, so that you can understand the firmware versions of your devices.

Added the function for resetting CyberPi

Choose Settings > Reset. When the reset starts, the following UI is displayed:

When the reset is complete, the homepage is displayed.

Resetting CyberPi deletes all the data you’ve uploaded to CyberPi, all the Wi-Fi settings, and the name you set for CyberPi.

Added the items Preset and My programs

After you choose Switch program, you can choose between Preset and My programs.

Program SNs are deleted to give space for program names.

(You can pull the joystick to left or right to switch between preset programs and user-defined programs.)

Preset programs

The Preset programs include several default programs. Names are given to help users understand the functions of the programs.

My programs

My programs are programs uploaded by users. Names you set for the programs on mBlock 5 are displayed.

Logic of overriding in program uploading

When a preset program is being executed, a program you upload replaces Program1 in My programs.

Improved the motion performance of mBot2

  • Used the chassis calibration function to reduce errors that may occur when mBot2 moves forward or makes turnings.
  • Updated the CyberPi firmware to control the accumulative errors of the encoder motors rotating in angles within ±3° in a single thread.
  • Deleted the default self-locking setting for the encoder motors in the CyberPi firmware, so that no unexpected sounds are made by the encoder motors when they are not moving (when their speed are set to 0).

Improved the Quad RGB Sensor extension

The user-defined color option is added.

Blocks and MicroPython APIs

Blocks (available in both Upload and Live modes) APIs Function
mbuild.quad_rgb_sensor.get_line_sta(position, index)

mbuild.quad_rgb_sensor.get_ground_sta(position, index)

mbuild.quad_rgb_sensor.get_white_sta(position, index)

mbuild.quad_rgb_sensor.get_red_sta(position, index)

mbuild.quad_rgb_sensor.get_yellow_sta(position, index)

mbuild.quad_rgb_sensor.get_green_sta(position, index)

mbuild.quad_rgb_sensor.get_cyan_sta(position, index)

mbuild.quad_rgb_sensor.get_blue_sta(position, index)

mbuild.quad_rgb_sensor.get_purple_sta(position, index)

mbuild.quad_rgb_sensor.get_black_sta(position, index)

mbuild.quad_rgb_sensor.get_custom_sta(position, index)

Position: “middle” or “all”

middle:L1, R1

all: L2, L1, R1,R2

The quad RGB sensor identifies the status of the color, line, and background.

Returning 1 means true, indicating that the specified color, line, or background is recognized.

Returning 0 means false, indicating that the specified color, line, or background is not recognized.

The final return value is a decimal integer value corresponding to the binary value of 0000–1111.

You can get the transcode of these blocks based on the preceding APIs.
mbuild.quad_rgb_sensor.set_led_color() Set the color of the fill light in line following. Using this function will overwrite the fill light color set for line-following learning.
mbuild.quad_rgb_sensor.close_led() Temporarily turns off the fill light. When any sensing function of the line-following sensor is used, the fill light is lit up again.
