MasterPi is an AI vision robot car powered by a Raspberry Pi 4B or 5. It carries a 5-degree-of-freedom robot arm with an HD wide-angle camera at the end, on a mecanum wheel chassis that moves in any direction. With OpenCV and a first-person view, it recognises and locates coloured blocks for colour sorting, line following and target tracking, then grabs and carries them, and a glowing ultrasonic sensor avoids obstacles. It is fully programmable in Python, can be controlled from the WonderPi app or PC software, and is assembled from step-by-step instructions.

Zeta42 is an authorised Hiwonder partner in the Middle East.

What it does

Built for.

Vision arm
The 5DOF arm (4DOF plus gripper) grabs and carries target items, and the wide-angle camera at its end lets it follow what it sees.
Mecanum movement
Four mecanum wheels move MasterPi forwards, sideways, diagonally and on the spot, along complicated routes.
AI games with OpenCV
Colour recognition, colour sorting, line following and target tracking use OpenCV image processing and the live camera view.
Control without code
Graphical PC software moves each servo with a slider and edits action groups, and a threshold tool fine-tunes colour detection in the LAB colour space.
App control
The WonderPi app for Android and iOS switches between game modes and drives the robot remotely.
Obstacle avoidance
A glowing ultrasonic sensor detects and avoids obstacles and changes its own light as it does.
