> Franka Robotics is offering this laboratory system in early access. It can be used both to show a movement to the robot and to check what the robot has learned from it.

The FR3 Duo is a two-arm system designed for research in “physical” artificial intelligence. According to Franka Robotics, the same machine is used to teleoperate the arms, record data and run the programs the robot has learned.

The manufacturer intends it for tabletop work. It states a reach of 855 mm and a payload of 3 kg for each arm.

The package includes two FR3 robots and a mounting kit. As options, Franka supplies Robotiq 2F-85 grippers, two RealSense D405 cameras mounted at the wrists and a ZED Mini stereo camera fitted as a head.

The manufacturer stresses an identical configuration from one laboratory to the next. According to Franka, this lets researchers reuse data collected elsewhere and compare their models under the same conditions.

Programmers can control the arms directly through the libfranka interface, which Franka distributes as open-source software. It can send commands at 1 kHz, or a thousand times per second.
