Model Comparison
WLKATA Robotic Kit Comparison
WLKATA's education range is really two arm families plus an AI learning platform: the 6-axis Mirobot (three kit tiers), the rebuildable 4-axis metal MT4 (two kit tiers), and the AI-HUB kits that teach vision, voice, and gesture control. The arms inside each family are identical - what changes between kits is the accessories, curriculum, and control options bundled around them. This guide compares the decision-relevant options using specifications from WLKATA's official product documentation. Prices shown are current store prices.
All models below are from a single manufacturer. RoboticsSelect is an authorized dealer; specifications come from the manufacturer's official documentation.

The short version: the Mirobot teaches 6-axis kinematics - the geometry of real industrial cobots - while the MT4 trades two axes for double the precision, double the payload, and a CNC metal frame students can take apart and rebuild. The kits within each family differ by accessories, not by arm.
AI-HUB learning kits
| Spec | AI-HUB AI Development Kit | AI-HUB AI Navigation Learning Kit |
|---|---|---|
| Price | $390 | $970 |
| Focus | Full AI development cycle: train and deploy models | Multimodal control: vision, voice, gesture |
| Compute | xFactory Brain (Linux; TensorFlow Lite, PyTorch Mobile, OpenCV) | xFactory Brain + Arduino board |
| Curriculum | 20-chapter AI textbook | Project-based multimodal textbook |
| Works offline | Yes | Yes (about 30-word offline voice model, retrainable) |
| Warranty | 12-month | 12-month |
Beyond these kits, WLKATA offers the industrial-grade 6-axis Haro380 for university research (PLC, ROS 2, and MATLAB workflows), the AI Vision Set for OpenMV machine vision, and complete training cells and lines - sorting, automobile assembly, fruit picking, and logistics - built from the same arms.
Which WLKATA kit should you buy?
Mirobot Education Kit
$1,680.00Choose this if you are equipping a first robotics classroom. One box covers a full teaching arc - Blockly for beginners, Python and G-code next, ROS and MATLAB for advanced students - with a conveyor belt and structured textbook included. It is the standard starting point for schools.
Mirobot Advanced Kit
$1,890.00Choose this if you want the flagship Mirobot configuration. It adds the AI voice-control box and electromagnetic gripper on top of the wireless teach pendant and full end-effector set, so students can drive the arm by voice, teach-by-demonstration, or code - the richest demo and project platform in the Mirobot family.
MT4 Edu Kit
$1,380.00Choose this if precision and mechanics matter more than 6-axis kinematics. The all-metal MT4 hits 0.1 mm repeatability with a 500 g payload, integrates with Arduino projects, and - uniquely - is designed to be disassembled and rebuilt by students with the included hex tool. It is also the lowest-priced arm kit in the range.
AI-HUB Navigation Learning Kit
$970.00Choose this if you already have arms and want to teach applied AI on top of them. Students build vision, voice, and gesture interfaces on the xFactory Brain and wire them into arm control - voice-commanded sorting, gesture drawing, accessibility projects - with an Arduino layer for real-time hardware lessons.
WLKATA comparison FAQs
Mirobot or MT4 - which suits my program?
Pick the Mirobot if your curriculum centers on kinematics: its 6+1 axes mirror full industrial cobots, and it carries the broadest software and curriculum support. Pick the MT4 if you teach mechanical engineering, precision, or Arduino integration: its 4+1 palletizing layout keeps the end effector pointing down (which covers most real pick-and-place automation), and the rebuildable metal frame turns assembly and tolerances into lesson content. Many programs run both - the software ecosystem is shared.
Are these kits precise enough for university research?
For coursework, demonstrations, and light prototyping, yes. The Mirobot's 0.2 mm and MT4's 0.1 mm repeatability suit teaching labs, and ROS 1/ROS 2 packages plus URDF models for Gazebo, MuJoCo, and NVIDIA Isaac Sim support simulation and sim-to-real work. For research requiring sub-0.1 mm tolerances or kilogram payloads, WLKATA's answer is the industrial-grade Haro380 line; ask us about availability and configuration.
Can schools order with purchase orders, and what warranty applies?
Yes. RoboticsSelect is an authorized WLKATA dealer, so institutional ordering with formal purchase orders is supported, and every kit carries the full 12-month manufacturer warranty on the arm (spare parts are covered on 3/6/12-month terms by part type). WLKATA's paid warranty extension program is available for multi-year classroom deployments. Contact support@roboticsselect.com or (412) 415-7375.
