Function List

Color Recognition and Tracking

Working with OpenCV, MentorPi can track specific color. After you select the color on the APP, it emits light of corresponding color and moves with the object of that color.

Target Tracking

Through vision positioning of the target object, the target object can be better targeted and tracked.

QR Code Recognition

MentorPi can recognize the content of custom QR codes and display the decoded information.

Vision Line Tracking

MentorPi supports custom color selection, and the robot can identify color lines and track them.

App Control

WonderPi app supports Android and iOS. Switch game modes easily and quickly to experience various AI games.

Wireless Handle Control

MentorPi supports wireless handle control and can connect to the robot via Bluetooth to control the robot in real time.

ROS Robot Operating System

Global Popular Robotic Communication Framework

ROS is an open-source meta operating system for robots. It provides some basic services, such as hardware abstraction, low-level device control, implementation of commonly used functionality, message-passing between processes, and package management. And it also offers the tools and library functions needed to obtain, compile, write, and run code across computers. It aims at providing code reuse support for robotics research and development.
