WLKATA MT4 Advanced Kit | 0.1mm Metal 4 Axis Robotic Arm, ROS2 Arduino, Rebuildable (Copy)

In 4-axis palletizing (the MT4), the end effector always points downward, simplifying programming and increasing payload capacity but limiting orientation flexibility. In 6-axis (the Mirobot and Haro380), the end effector can rotate and tilt in any orientation, supporting more complex tasks but adding kinematic complexity. Palletizing covers a large portion of real-world automation (pick-and-place, stacking, sorting) where orientation flexibility is unnecessary.

The MT4's metal CNC frame and 4+1 DoF structure (vs. the Mirobot's 6+1 DoF plastic structure) reduce mechanical compliance and tolerance stack-up. Fewer joints mean fewer cumulative error sources, and metal joints are stiffer than plastic. The result is 0.1 mm repeatability vs. the Mirobot's 0.2 mm at a similar price point.

Yes. The MT4 is specifically designed for reverse engineering. The CNC metal frame uses hex screws throughout, allowing students to disassemble and reassemble the entire arm with the included hex tools. This teaches mechanical assembly, joint design, and the relationship between mechanical tolerances and final precision. Repeated rebuild cycles are part of the intended use.

The 500 g standard payload is the reliable, repeatable rating. The 600 g maximum applies under specific conditions (slow motion, balanced load near the base, optimal joint angles). For consistent operation, design applications around the 500 g standard rating; the 600 g number represents the absolute envelope, not continuous-use capacity.

Yes. Full Arduino Mega 2560 compatibility is supported via the WLKATA Arduino library. Students can combine the MT4 with custom sensors, actuators, and microcontroller-based projects, building integrated robotics applications that go beyond what the arm alone can do.

The Advanced Kit includes an extended end-effector collection beyond the Essential Kit's basic gripper set. Typical contents include two-finger gripper, three-finger soft gripper, suction cup with multiple head sizes, and pen holder. Exact contents vary; the WLKATA product page lists current configuration.

Yes. WLKATA's Conveyor Belt Set and Sliding Rail Set are designed specifically for integration with the MT4 (and other WLKATA arms). The combination enables mini-production line projects: parts arrive on the conveyor, the MT4 picks and sorts to drop locations, optionally on a moving base for extended reach. These accessories are sold separately.

Yes. The MT4 has ROS2 packages on GitHub. University students can use the MT4 for SLAM, motion planning, and Gazebo-simulated digital twin work. The 4+1 DoF kinematic model is sometimes easier to teach in ROS than full 6-axis arms, making the MT4 a good entry point for ROS courses.

Yes. The MT4 works with WLKATA's OpenMV AI Vision Set and OpenCV Advanced Vision Suite. For custom AI integrations, the open Python API supports TensorFlow, PyTorch, YOLOv5, OpenCV, and OpenMV. Vision-guided pick-and-place, color sorting, and shape recognition are common project types.

The MT4 has higher precision (0.1 mm vs. 0.2 mm), higher payload (500 g vs. 250 g), metal vs. plastic construction, and a rebuildable design. The Mirobot has more DoF (6 vs. 4), more programming language options, broader curriculum support, and the AI voice control option in the Advanced Kit. Schools teaching kinematics-heavy curriculum benefit from the Mirobot's 6 DoF; schools teaching mechanical engineering and Arduino integration benefit from the MT4's rebuildable design.

RoboticsSelect is an authorized WLKATA dealer, so the full 12-month manufacturer warranty applies to all MT4 Advanced Kit purchases. Authorized dealer status ensures warranty claims are processed through verified channels and provides access to WLKATA's paid warranty extension program.
