WLKATA MT4 Review: Specs, Price and Applications of the Four-Axis Metal Desktop Robot Arm
Updated: 7 days ago
The WLKATA MT4 is a four-axis desktop robot arm with a CNC metal frame, a payload of 500 g, a reach of 359 mm and 0.1 mm repeatability, listed from USD 1,380 as an Education Kit. This review covers its specifications, design, programming options, applications and price.
Quick Verdict
The MT4 is WLKATA's four-axis arm. With fewer axes than the Mirobot it is simpler to program, and its metal frame gives it twice the payload and twice the accuracy of that model: 500 g and 0.1 mm. It weighs 3.1 kg and comes with a wide choice of grippers. It suits pick and place, sorting and classroom work on smart factory concepts. A four-axis arm cannot tilt its tool freely, so it is not a substitute for a six-axis arm where orientation matters.

Design and Build Quality
The MT4 is built on a CNC-machined metal frame, and the maker describes its joints as quiet and accurate. At 3.1 kg it is about twice the weight of the Mirobot, and the stiffer structure is reflected in the figures: 0.1 mm repeatability and a 500 g payload. The Advanced Kit comes in a carry case with an electromagnetic gripper, an electric gripper, a metal servo gripper, two-finger and three-finger soft grippers, suction cups in three sizes, a pneumatic box and a pen holder.
