Why Researchers Choose the ViperX Follower for Bimanual Aloha Setups
Not all bimanual Aloha configurations require the same follower arm. The ViperX Aloha is the choice for research teams whose tasks demand a longer working reach and higher payload capacity than the standard WidowX-based follower configuration provides. With a 750mm reach and 1500mm tip-to-tip span inherited from the ViperX platform, the ViperX Aloha follower arm covers a wider bimanual workspace — critical for tasks involving extended tool use, larger object manipulation, or experiments designed around a deeper working envelope. At 6 Degrees of Freedom with 1mm repeatability, it delivers the same joint-space precision and session-to-session consistency required for high-quality imitation learning datasets. The ViperX Aloha is Aloha V2-compatible and has been validated for use in research workflows that produce datasets compatible with Aloha, BiACT, OCTO, π0, and Aloha Unleashed. If your bimanual research tasks sit at the edge of what a standard follower arm can reach, the ViperX Aloha is purpose-built for that requirement.

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.
