WLKATA MT4 Advanced Kit is a 4-axis educational robotic arm, fully constructed from metal (CNC aluminum alloy), specifically designed for interactive learning, reverse engineering, and "Smart Factory" industrial simulations.

Unlike other robotic arms, the MT4 is modular and allows for complete disassembly and reassembly, making it ideal for understanding robotics mechanics and design. The Advanced Kit version expands the control and manipulation capabilities by adding AI voice recognition technology and a comprehensive range of end-effectors.

It is a "plug-and-play" system that supports visual programming (Blockly), Python, and G-code, and is fully compatible with the Arduino ecosystem, ROS, MATLAB, and simulation platforms such as NVIDIA Omniverse or RoboDK.
