3 🕹 Play with Nybble Q

Last updated
The Nybble Q robot is equipped with various sensors and modules including a gyroscope, touch sensors, ultrasonic sensors, voice recognition, and Bluetooth. You can try patting it or stroking its back to observe its reactions.
You can interact directly with the robot by following the simple quick start guide below. You can also download mobile or computer apps to explore more advanced controls. Developers familiar with coding can also program the robot through graphical interfaces, Arduino, Python, or Raspberry Pi platforms.
You can control the Petoi robot to perform various skills using voice commands without a wake word. The robot currently supports two languages (Chinese and English) and comes with 40 preset voice commands. Additionally, you can record any sound clip to create up to 10 custom commands.
Testing
When the robot starts up, voice recognition defaults to English mode. Try saying "hello" to the robot, and it will perform a greeting gesture.
Turning the Voice Recognition Feature on and off
By default, voice commands are always enabled, so the robot continuously listens to ambient sounds, which can easily result in accidental activation of voice commands.
To avoid unintentionally triggering the robot’s response to voice commands—for example, when conversing with others—you can say "Be quiet" to the robot, and the voice command module will be disabled.
To re-enable the voice recognition feature, you can say "Play sound".
Custom Commands (Advanced)
When the robot is operating in English mode, you can activate the custom voice command mode by saying the voice command "Start learning" or entering XAe in the serial port monitor. Follow the voice prompts to record your custom voice commands. To exit the custom voice command mode, say "Stop learning" or enter XAf in the serial port monitor.
You can record up to 10 custom voice commands.
After exiting the custom voice command mode, you can trigger the robot’s corresponding actions by speaking any of the recorded voice commands.
To delete all custom voice commands at once, say the voice command "Clear the learning data".

Nybble Q features four independent touch areas on its back, located on the left side, right side, center, and near the tail. Each touch area is pre-programmed with distinct interactive responses—let’s explore them!
Touch Areas & Responses：
Left Area: Lightly touch to make Nybble Q turn its head to the left and look back.
Right Area: Lightly touch to make Nybble Q turn its head to the right and look back.
Center Area: Lightly touch to wake up the device or trigger a random action.
Touch near the tail to activate lively movements like tail wagging or back arching.
Usage Tips:
Nybble Q will not execute new actions if the same spot is touched repeatedly or if two touch points are pressed simultaneously.
Wait for the current action to complete before triggering a new command to ensure smooth interaction.
Obstacle Avoidance
When an obstacle is detected ahead, the robot reacts differently based on the obstacle's distance.
Randomly sitting down, turning, or reversing.

Instructions:
The robot and micro:bit controller connect via Bluetooth.
Please turn on the micro:bit controller first, then power on or restart the robot. Please do not reverse this order.
After powering on, the controller and robot will automatically pair. If multiple robots are powered on, pairing follows a first-come, first-served rule.
A connection sound plays once the device is paired, and the letter N (for Nybble) is displayed.

Basic Operations
Joystick (left side):
Controls movement: forward, backward, left, right, and diagonally.
Pushing the joystick fully left/right makes the robot spin in place.
Quickly push the joystick forward twice to trigger a rapid forward dash.
Single/Dual Button Actions:
Logo (touch): Rest mode.
A: Long press to rotate the robot’s head.
B: Long press to synchronize the robot’s body movement with the controller’s gyroscope.
C: Crawl.
D: Kick.
E: Toggle sitting/standing.
F: Hug.
A+B: Cheer.
C+E: Boxing.
D+F: Face-washing.
E+F: "Lucky Cat" waving.
Button + Joystick Combo:
Hold a button and move the joystick to specify a direction.
By default, a single tap/release of the joystick triggers random direction movement.
Limitations:
The joystick requires 300 ms to detect double-tap events, causing slight delays in button+joystick forward actions.
Single-button actions may trigger before combo commands.
Rapid button presses during control switching may fail to register.
Customizing Controller Functions (Advanced):
In code, button functions are defined as:
keyCmd = [
# Touch, A, B, C, D, E, F, A+B, C+E, D+F, E+F
["d", "keyGyro","keyJoystick","kcr", "kkc" ,"stateSwitch" , "khi", "kchr", "kbx", "kwsf","klucky"], # Nybble
]
You can modify the action commands or remap button combinations.
Currently, only A+B, C+E, D+F, and E+F are reserved for dual-button combos.
Additional combos (e.g., A+F, B+D) can be added but may be less ergonomic to press simultaneously.
