Overview

The WidowX AI is Trossen Robotics' most advanced research manipulator, designed for embodied-AI and imitation-learning workflows. It is the arm used on all four Trossen AI platforms (ALOHA V2-compatible), functioning as both the leader arm for teleoperation and the follower arm for task execution. Sold in Base, Leader (ambidextrous pincher) and Follower (precision gripper + Intel RealSense D405 camera) configurations, it is a 6-degree-of-freedom arm with roughly 769 mm reach and a 1.5 kg payload, controlled over Ethernet by Trossen's iNerve controller. Its predecessor in this role was the Interbotix WidowX 250 S (6-DoF, ~650 mm reach, 250 g working payload). Software support spans LeRobot, Hugging Face, ROS 2, MuJoCo, Gazebo, NVIDIA Isaac and the Trossen Data Collection SDK.
