Price Match Guarantee

We match the lowest online price on the products we sell — and if you find a lower price on a product listed over $2,000, we will beat it by $50. Purchase from our store first, then send proof of the lower price (a screenshot, invoice, or email) to support@roboticsselect.com and we will refund the difference.

A few requirements: the competitor must be an authorized online retailer of the product with the item in stock on their website, must be online-only (no retail location), and cannot be a discounter or auction site such as eBay or Overstock. The comparison includes the item price and shipping charges but excludes sales tax.

Rebates, buy-one-get-one offers, and special once-a-year promotions such as Black Friday and Cyber Monday are not eligible. Certain exceptions may apply.

Returns & Refunds

Cancel any time before your order ships for a full refund, free of charge. Custom and made-to-order products are put into production for your specific order, so all sales are final on those items.

You have 30 days from the date you receive an item to start a return — email support@roboticsselect.com or call (412) 415-7375. Products must be returned unopened and unused. Some brands set their own return terms, and the brand-specific policy on the product page overrides the general 30-day window; if the manufacturer will not permit a return, we cannot offer one.

Outright returns after shipment incur a 25% cancellation fee plus return shipping, and manufacturer restocking fees (usually around 20%) may also apply — return shipping costs are the customer's responsibility. Refunds go to your original payment method and are processed within 10 days of our receiving the returned product.

Inspect the package when it arrives: note any damage when signing for delivery and send photos to support@roboticsselect.com within 24 hours — freight damage claims are not valid after 24 hours.

Full Refund Policy

WLKATA MT4 Education Kit

Overview

The WLKATA MT4 Education Kit is a 4-axis desktop robotic arm with a rebuildable, all-metal design, built for robotics education, research, and light industrial tasks. It uses a 4+1 axis palletizer layout, which means the end effector always faces downward, the same arrangement used by real palletizing robots, making it a strong fit for teaching pick-and-place, sorting, and assembly.

The MT4 has a repeatability of 0.1 mm, a 359 mm maximum reach, and a 500 gram standard payload (up to 600 grams). Its standout feature is the 100 percent CNC metal frame that students can take apart and rebuild with a hex tool, giving hands-on insight into how a robot is built. The arm comes fully assembled and ready to use out of the box.

It is highly open: it supports no-code control through a smartphone app, an AI voice box, or even an LLM, and scales all the way up to ROS, MATLAB, and machine-vision tools. A free, illustrated textbook and teacher guidebook, plus optional K-12 and university curriculum, round out the kit.

Applications

WLKATA MT4 pick-and-place and sorting with a conveyor

The MT4 Education Kit suits middle school, high school CTE, and university courses, as well as research and light industrial use. Its palletizer layout and open control make it a practical platform for teaching real automation: pick-and-place, color and shape sorting, palletizing, and smart-factory workflows.

Because it integrates with conveyors, sliding rails, AI cameras, and an AGV base, students can build complete mini production lines on a desktop. Its support for ROS, MATLAB, and machine-vision libraries lets advanced users prototype real workflows, while the rebuildable frame and free textbook keep it approachable for beginners.

Setup and Getting Started

Unbox and inspect: Remove the MT4 and accessories, and check for shipping damage. The arm ships fully assembled.
Place the arm: Set it on a stable surface with room for its 359 mm reach.
Connect power and control: Connect the controller and extender box, and pair over USB, Bluetooth, or WiFi.
Choose a control method: Start with the app or WLKATA Studio (Blockly and teach-and-play), or use the AI voice box.
Attach an end effector: Fit a gripper or suction cup for your first task.
Build a workflow: Follow the included textbook to run pick-and-place, then add a conveyor or AI camera for sorting projects.

Frequently Asked Questions

What is included with the MT4 Edu Kit?

The WLKATA MT4 arm ships fully assembled, along with the control box and extender box, a servo gripper and additional end-effector tools per kit configuration, the hex tool used for disassembly and rebuilding, WLKATA Studio and BlockFactory software, and a free illustrated student textbook (200+ pages) with a teacher guidebook.

Who is the MT4 Edu Kit for?

Middle school, high school CTE, and university courses, plus research and light industrial use. Control scales from no-code options (smartphone app, AI voice control box, or LLM control) through Blockly, teach-and-play, Python, and G-code in WLKATA Studio, all the way to ROS, ROS2, MATLAB, CoppeliaSim, RoboDK, and machine-vision libraries, so the same arm serves beginners and advanced users.

How precise is it, and what payload can it handle?

Repeatability is 0.1 mm, maximum reach is 359 mm, and payload is 500 g standard with a 600 g maximum. The 4+1 axis palletizer arrangement keeps the end effector facing down, the same layout used by real palletizing robots, which makes it a strong fit for teaching pick-and-place, sorting, and assembly.
