R3T-03 is a strong, compact 4-axis industrial robot that carries 6 kg within a 650 mm reach – double the payload of R3T-02 in the same footprint. It moves the tool at up to 1,100 mm/s and repeats positions within ±0.05 mm, and it can be integrated with machine vision for smart picking and inspection. The complete system includes the robot arm, a control box with four AC servo drivers and 32 I/O channels, and an 11.6-inch touch-screen teach pendant. Programs are created by point-to-point teaching on a graphical interface or by importing G-code, and Modbus TCP/IP makes it easy to connect to PLCs and machines. Designed and built by Robot3T in Vietnam.

Frequently asked questions
Which R3T 4-axis robot should I choose?
All share the same controller and pendant. R3T-01: 1 kg, 850 mm reach. R3T-02: 3 kg, 650 mm. R3T-03: 6 kg, 650 mm. R3T-05: 10 kg, 950 mm. Tell us your part weight and workspace and we will advise.
Can it connect to my PLC and machines?
Yes. Use Modbus TCP/IP or the 24 digital and 8 analog I/O channels to exchange signals with PLCs, sensors, grippers and machines.
Do you build complete cells?
Yes. Robot3T designs grippers, fixtures, conveyors and safety guarding, and delivers turnkey automation cells with commissioning and training.
Do you ship outside Vietnam?
Yes. Contact sales@robot3t.com for a quote including shipping to your country.
