Trossen Robotics WidowX 250

WidowX 250 机械臂Common

Trossen Robotics' low-cost 6-DoF research arm, the platform behind the BridgeData datasets.

The WidowX 250 is a desktop arm in Trossen Robotics' Interbotix X-series, driven by ROBOTIS Dynamixel X-series servos. The 6-DoF version, the 250s, has a reach of about 650 mm and a rated payload of 250 g, is priced far below an industrial arm, and supports ROS. It is common in the robot-learning community: Berkeley's BridgeData V2 dataset was collected on a WidowX 250, and that data is included in Open X-Embodiment, Octo, and OpenVLA; SimplerEnv also has a matching WidowX evaluation scene, and ALOHA's leader arms use the same WidowX. Its drawbacks are a small payload and only middling precision.

ExampleThe OpenVLA paper runs its real-robot evaluation on a WidowX 250 in BridgeData-style scenes.
