The Interbotix WidowX 250 6DOF is a 6-degree-of-freedom research robot arm built on DYNAMIXEL X-series smart servos, with a 650 mm reach and roughly 0.25 kg working payload. It is best known as the leader (teleoperation) arm in Stanford's ALOHA, ALOHA 2, and Mobile ALOHA bimanual manipulation platforms.

The Interbotix ViperX 300 6DOF is a 6-axis research robot arm from Trossen Robotics (Interbotix brand), built on DYNAMIXEL X-series smart servos. With ~750 mm reach and a full 360° range, it is best known as the follower arm in the ALOHA, ALOHA 2, and Mobile ALOHA bimanual imitation-learning platforms.

ALOHA 2 is an enhanced low-cost reference design for bimanual teleoperation and imitation-learning data collection, sold as kits by Trossen Robotics. A stationary tabletop rig pairs two low-cost leader arms with two follower arms (6-DOF each) for leader-follower puppeteering, adding low-friction rail grippers, passive gravity compensation, and Intel RealSense D405 depth cameras. It ships with a high-fidelity MuJoCo model and open-source hardware, and underpins large-scale imitation/VLA datasets and Google DeepMind's Gemini Robotics demos.

Trossen Robotics Mobile AI is a wheeled bimanual manipulation platform and the successor to Mobile ALOHA. It combines two Leader-Follower WidowX AI arm pairs (four 6-DOF arms total) with three Intel RealSense D405 depth cameras on a mobile base, targeting imitation-learning and teleoperation research with a LeRobot / ROS 2 / Isaac / MuJoCo / Gazebo software stack.

Trossen Robotics Stationary AI is a stationary bimanual imitation-learning workstation and the current successor to ALOHA Stationary. It ships as two leader-follower WidowX AI arm pairs (four 6-DoF arms total) with four Intel RealSense D405 RGB-D cameras, wired for leader-follower teleoperation data collection and policy training across LeRobot, Hugging Face, ROS2, NVIDIA Isaac, MuJoCo, Gazebo, and OpenPI/pi0.

The WidowX AI is Trossen Robotics' 6-DoF articulated manipulator that powers its Trossen AI (ALOHA-successor) imitation-learning platforms, shipping as both the leader (teleoperation) and follower (task-execution) arm. It offers ~769 mm reach, a 1.5 kg payload, and 1 mm repeatability, is driven over Ethernet by the iNerve controller, and integrates natively with LeRobot, Hugging Face, ROS 2, MuJoCo, Isaac and the Trossen Data Collection SDK.
