Pico Robot Car Onboard Multi Sensor Module

Based on Raspberry Pi Pico board

Raspberry Pi Pico is a low-cost, high-performance microcontroller. It adopt the RP2040 chipdeveloped by Raspberry Pi, and uses MicroPython as the programming language. Some complete development material tutorials will be provided, which is very suitable for beginners to learn programming and build some robot cars.

Programming with MicroPython

Raspberry Pi Pico is a compact microcontroller development board. Combined with the Python operating system, it can be used to build various electronic proj-ects. Through MicroPython, we can quickly realize our creative ideas.

Function list

Support APP remote control by Bluetooth

APP can control the motor motion state, OLED display, buzzer, RGB light, line tracking, obstacle avoidance, voice control mode and other functions of Pico robot.
iOS / Android

Infrared remote control

Pico robot can receive the signal sent by the infrared remote controller and realize different actions of the remote control car by identifying the code value of each remote control key.

Tracking

Adjust the moving direction of the robot through the feedback signal from the tracking sensor, which can make robot car moves along the black line track.

Cliff detection

The signal detected by the infrared sensor is judged in real time. When the robot is close to the edge of the table, the infrared sensor cannot receive the return signal, and the robot will retreat and stay away from the “cliff”.

Ultrasonic obstacle avoidance

The ultrasonic signal is transmitted through the ultrasonic sensor, and the signal return time is calculated to judge the distance of the obstacle ahead, which can realize the function of distance measurement and obstacle avoidance of the robot.

Object following

Through distance measurement by ultrasonic sensors in real-time enables the car to keep a fixed distance from the obstacles ahead, which can achieve the effect of object following.

Voice control robot

The robot detects the current volume of the environment through the sound sensor. When the volume is greater than the threshold, the robot will whistle and move forward a certain distance, and the RGB lights will turn on corresponding lighting effects.

Light seeking following

By reading the values of the two photosensitive sensors, comparing the two values, judging the position of the light source to control the direction of movement of the robot.

Colorful RGB light

On-board 8 programmable RGB lamps, which can realize a variety of different effects, such as breathing light, marquee.

OLED display in real time

Many data of ultrasonic module, light sensor and sound sensor can be displayed on OLED in real time.

Hardware configuration

No welding plug and play
