Reference Price
Last listed at $6,742.95 on Trossen Robotics' own store before going out of stock — treat this as a historical rather than current price. The listing is marked sold out, with a notice that a "new generation" product line is available for pre-order as a replacement; no public specs or pricing for that successor were found, and Trossen directs interested buyers to contact sales directly.
Sensors & Hardware
The ViperX-300 6DOF runs on 9 DYNAMIXEL smart servos — seven XM540-W270 units for waist, shoulder, elbow, wrist-angle, and forearm-roll, plus two XM430-W350 units for wrist rotation and the parallel gripper — at 4096-position resolution over a 1Mbps bus. Trossen ships full URDFs, MoveIt configs, and Gazebo support; the same stack powers ALOHA's bimanual teleoperation arms.
Insights
The ViperX 300 6DOF ships with open CAD files and 3D-printable end-effectors, and Trossen documents its complete per-joint servo specs — a level of openness and repairability uncommon among comparable robotic arms. It also carries full ROS and ROS 2 support (MoveIt, Gazebo, Python API).
Firmware & Community
Interbotix/interbotix_ros_manipulators
Trossen Robotics' own official ROS/ROS 2 packages for the X-Series arm family, including the ViperX-300 — used as the follower-arm platform in Stanford's open-source ALOHA teleoperation system.
Specs sourced from Trossen Robotics' official product page (trossenrobotics.com/viperx-300) and its X-Series arm documentation (docs.trossenrobotics.com, vx300s specification page), including the full per-joint servo table. Moved from Featured to Under Review on a rechecked basis: Trossen's own store now lists the original 6DOF kit under SKU "KIT-VIPX300-6DOF-OLD" (sold out), and even its follow-on, the "ViperX 300 S," is itself now labeled a "legacy arm" and also shown sold out, with a further, still-unnamed new-generation line available only for pre-order. No public specs or pricing for that newest generation were found; Trossen directs interested buyers to contact sales directly. Pricing above reflects the last listed price for the (now doubly-superseded) unit this entry covers, not a current one. robotindex does not sell this product.
