Why a Matched Leader Arm Set Changes Your Setup Workflow
Building a bimanual Aloha configuration from individual components requires sourcing, configuring, and calibrating each arm separately. The WidowX Aloha Set removes that step. As a pre-configured matched leader arm pair, it ships ready for direct integration into your bimanual teleoperation workflow — both arms pre-aligned to the same hardware specification, with consistent grip configurations and cable management already handled. This matters for research teams working under time pressure, where hours spent on hardware configuration are hours not spent collecting data or iterating on models. The matched pair format also removes a source of subtle inconsistency that can emerge when sourcing leader arms at different times or from different production batches. For labs that already have follower arms in place — or are building around an existing WidowX AI configuration — the WidowX Aloha Set is the fastest path to a complete, calibration-ready bimanual teleoperation setup. Every unit ships with startup documentation and lifetime U.S.-based engineering support from the Trossen team.

Gravity Compensation
Arms hold their positions even when you release your grip on them

Easily Repairable
The X-Series arms are made for the lab, our arms are intended to be worked on and we've made it as easy as possible to keep your manipulator up and running. Quickly and easily swap out motors that need to be replaced, lengthen or shorten the arm to your needs. Everything you need to repair your platform is kept in stock, making it easy to keep your equipment up and running with minimal downtime.
ROS 2 Support
Packages for ROS and ROS 2 make it easy to get started with the arm. These packages include full meshes and URDFs (including accurate inertial models for the links), a driver node to control the physical robot arm and publish joint states, as well as simulation (Gazebo) and motion planning (MoveIt) support. Several example packages are also included to demonstrate the potential uses of the core packages.

MoveIt Support
MoveIt is the most widely used software for manipulation and has been used on over 150 robots. It is released under the terms of the BSD license, and thus free for industrial, commercial, and research use. By incorporating the latest advances in motion planning, manipulation, 3D perception, kinematics, control and navigation, MoveIt is state of the art software for mobile manipulation.
Gazebo Support
Robot simulation is an essential tool in every roboticist's toolbox. A well-designed simulator makes it possible to rapidly test algorithms, design robots, perform regression testing, and train AI system using realistic scenarios. Gazebo offers the ability to accurately and efficiently simulate populations of robots in complex indoor and outdoor environments. At your fingertips is a robust physics engine, high-quality graphics, and convenient programmatic and graphical interfaces. Best of all, Gazebo is free with a vibrant community.
