Bittle Sensor Pack

This is the sensor expansion package of the Bittle robot dog. It can give Bittle robot dog visual recognition, voice recognition, feeling environment, and other abilities, making it a smart dog~

Features 

• The sensor module of the Bittle sensor package can be used with our robot dog Bittle.
• robots can use cameras and laser scanners for visual inspection，it is more nuanced.
• Plug and play with Grove connector
• Low power consumption

The Bittle sensor kit includes ultrasonic distance measurement, CyberEye, a 0.96-inch OLED display, and other modules. The robot dog Bittle can be used with these modules to achieve powerful functions such as visual inspection and language recognition in the field of machine learning.

There are following modules in Bittle Sensor pack:

• Grove - Ultrasonic Distance Sensor
• Grove - mini PIR motion sensor
• CyberEye Intelligent Vision Sensor
• Grove - Speech Recognizer
• Grove - 0.96” OLED Display
• Grove - Sound Sensor

Ultrasonic Distance Sensor
The Grove - Ultrasonic Distance Sensor utilizes ultrasonic waves to measures distance. It can measure from 3cm to 350cm with the accuracy up to 2mm. It is a digital signal sensor, which means it needs to be connected to Grove ports starting with letter D. Link to Lesson:   Utrasonic Sensor - Maze Challenge

Mini-PIR Motion Sensor
Grove - mini PIR motion sensor can detect movement of objects, people, or animals by picking up one's infrared radiation. When an object, such as a person, passes in front of the background, such as a wall, the temperature at that point in the sensor's field of view will rise from room temperature to body temperature, and then back again. The sensor converts the resulting change in the incoming infrared radiation into a change in the output voltage, and this triggers the detection. It is a digital signal sensor, which means it needs to be connected to Grove ports starting with letter D.  Link to Lesson:   PIR motion Sensor - Always on guard

CyberEye Intelligent Vision Sensor
CyberEye Intelligent Vision Sensor is a camera sensor coupled with an ESP32 microchip, that can perform multiple computer vision functions, including color recognition, ball recognition, human sensing, card pattern (shapes, traffic signs, and numbers) recognition. All the visual recognition algorithms on the CyberEye Vision Sensor are processed locally, with no need for the network.  Link to Lesson:  Vision Sensor - Gesture detection,  Object following

Grove - Speech Recognizer 
Grove - Speech Recognizer can recognize 22 pieces of commands including 'start', 'stop', 'Play music' and so on. The wake-up word for starting speech recognition is Hicell. When it recognizes the wake-up word, LED turn red, then you can say the command word, if it recognize the command word, LED will turn blue. It is a digital signal sensor, which means it needs to be connected to Grove ports starting with letter D. Link to Lesson:   Speech Recognizer  - Sound activation

Grove - 0.96" OLED Display
The Grove - 0.96" OLED Display is a monochrome(white) 128×64 pixels passive display matrix module with Grove I2C Interface. It can be used to display debugging information or just draw funny faces.  Link to Lesson:   OLED Screen  - Displaying messages

Grove - Sound Sensor
Grove - Sound Sensor can detect the sound intensity of the environment. The main component of the module is a simple microphone, which receive sound and convert it to electrical signal, which can be processed by Bittle mainboard. It is an analog signal sensor, which means it needs to be connected to Grove ports starting with letter A.
