Robotis AI Worker

AI Worker (model name FFW) is a semi-humanoid from South Korea's Robotis, maker of the widely used Dynamixel servo actuators. It has two 7-DoF arms, a camera head and a torso lift, on either a mobile base or a fixed stand. Companies and labs use it to collect teleoperation data and train robots by imitation, and its software stack is open source.

Design and technology

There are two versions. The mobile FFW-SG2 is 162 cm tall, weighs 90 kg and has 25 DoF: 7 per arm, 1 per gripper, 2 in the head, 1 in the lift and 6 in a swerve-drive base rated at 1.5 m/s. It runs on a 25 V, 80 Ah (2,040 Wh) battery good for up to 6 hours of continuous work and uses two lidars and an IMU for navigation. The stationary FFW-BG2 (85 kg, 19 DoF) has no base and runs on mains power.

Arm reach is 641 mm to the wrist. Payload is 3 kg per arm nominal (6 kg dual) and 5 kg per arm peak (10 kg dual). Standard end effectors are Robotis' own two-finger RH-P12-RN grippers. The head carries a Stereolabs ZED Mini stereo camera and the wrists two Intel RealSense D405 cameras. Compute is an NVIDIA Jetson AGX Orin 32 GB, and the joints use Dynamixel actuators.

Software and AI

AI Worker runs ROS 2 with Robotis' Physical AI Tools and is built for imitation learning: an operator teleoperates the robot, the recorded data trains a model, and the model is deployed back on the robot. Robotis publishes code, hardware designs, simulation tools and datasets under Apache 2.0, with Python, C++ and web UI interfaces. Data collection uses a light leader unit, the FFW-LG2 (3 kg, 22 DoF), which the operator moves to drive the robot's arms.

Applications

Robotis points to wire-harness assembly, welding, inspection and logistics, all areas short of labor. The robot learns tasks from human demonstrations and refines them with imitation and reinforcement learning. Its open software and simulation assets also make it useful for research teams. Robotis has not named industrial customers.

Manufacturer

Robotis was founded in Seoul in 1999 by Kim Byung-soo. Its Dynamixel actuators, sold since 2003, made up 97% of 2025 revenue (38.9 billion won). The company has been listed on Kosdaq since 2018, and LG Electronics is its second-largest shareholder with 6.6%. In 2026 Robotis also showed a bipedal humanoid, AI Sapiens, and is building an actuator plant in Uzbekistan.

Price and availability

The robot is made to order and ships from Robotis' factory in Korea. Robotis' US store lists the mobile version at a regular price of 69,000 dollars including import tariffs with a standard 8-week lead time, while asking buyers to request a quote. European reseller Generation Robots lists it from 54,000 euros before VAT (64,800 euros with VAT).

Compared with the catalogue

• At 162 cm the Robotis AI Worker is taller than 26% of the humanoids in the catalogue (median: 170 cm).
• It has 25 degrees of freedom against a catalogue median of 28; more degrees of freedom usually means finer arm and hand movement.
• Its weight of 90 kg (catalogue median: 65 kg) matters for transport and for working around people.
• It is the only Robotis model in the catalogue and one of 9 humanoids from South Korea.
